is femoral retroversion a disability

J Child Orthop. These methods differ regarding the definition of the second reference point to determine the proximal reference line (Table 2). However, in excessive cases, surgery may be needed to correct the rotation. Femoral retroversion | definition of femoral retroversion by Medical dictionary femoral retroversion Also found in: Dictionary, Thesaurus, Encyclopedia. SCFE: clinical aspects, diagnosis, and classification. The source of all of my pain was the retroversion of my femur. This condition can affect patients of all ages and leads to abnormal stress in the low back, hip and knee, as well as an abnormal gait (walking stance). [42] found higher mean femoral neck version of 9.3 in seven patients (five with obesity) with unilateral SCFE. After applying prespecified inclusion and exclusion criteria, we included 79 patients. Acetabular retroversion (AR) consists of a malorientation of the acetabulum in the sagittal plane. Int Orthop. Femoral retroversion is a positional deformity caused by contracture of the external rotator muscles of the hip. HHS Vulnerability Disclosure, Help In this regard, a routine assessment of femoral version can refine the indications for isolated offset correction versus femoral osteotomies with or without offset correction, depending on the severity of the slip and rotational malalignment. What is femoral anteversion? [19] method -19 16 [95% CI -25 to -12] versus -19 16 [95% CI -23 to -15]; p = 0.90, respectively) (Table 5). Elise struggled with femoral retroversion, also known as hip retroversion which is a condition related to hip dysplasia. [19]) compared with distal landmarks to define the femoral reference axis (47% for the method of Tomczak et al. coronary heart disease, and other diseases due to long-term disability, bringing economic and spiritual double blows to patients and families. This position keeps the femoral head within the socket which minimizes pain. An important mark of this deformity is the reduced or absent offset between the femoral head and the neck, which can be radiographically graded. In severe cases, however, surgery may be needed to correct the rotation. Surgical treatment of symptomatic post-slipped capital femoral epiphysis deformity: a comparative study between hip arthroscopy and surgical hip dislocation with or without intertrochanteric osteotomy. The state of being turned or tilted back. What are the causes of femoral retroversion? The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. 22. Recognizing this impairment and its impact on a patient's function is . The exact cause of femoral retroversion is unknown. The hip joint is where the femoral head (the top of the femur) meets the pelvis. Femoral impingement in maximal hip flexion is anterior-inferior distal to the cam deformity in femoroacetabular impingement patients with femoral retroversion : implications for hip arthroscopy Unlike in- toeing, out-toeing may lead to pain and disability as the child grows into adulthood. To the best of our knowledge, there are no normal reference values for CT-based femoral neck version measurements in children. The prevalence of femoral retroversion (< 0) was compared using a chi-square test. acetabulum - tends to be deformed in front, there may be eversion of the labrum, the bony + cartilaginous part of the acetabulum is broken, the dislocation is directed ventrally and proximally; neck of the femur - antetorsion associated with valgus, pressure change on the edge of the acetabulum 2002;2:8. 2016;98:127-134. retroversion, reduced thoracic kyphosis (TK), increased knee flexion, and increased pelvic shift to balance the SVA, indicat-ing that other sagittal parameters influence sagittal align-ment.9,10 Additionally, cervical sagittal parameters relate to HRQoL and disability, stressing the importance of considering is femoral anteversion a disability. Clin Orthop Relat Res. During the early childhood some degree of internal rotation is always present. We could show that assessing the femoral necks orientation alone underestimates the degree of external rotation subsequent to displacement of the epiphysis by 13 9 (Table 4). 2013 Jul;471(7):2163-72. doi: 10.1007/s11999-012-2715-7. 2017;11:284-288. Retroversion refers to an abnormal backward rotation of the hip relative to the knee. Femoral retroversion causes hip impingement, similar to the impingement and posterior instability that occurs in total hip arthroplasty. It is a structural adaptation that alters the shape of the thigh bonea point past sports medicine staff and physical therapists have failed to apply in Andrew's case. Because the lower part of the femur is connected to the knee, this also means that the knee is twisted outward relative to the hip. Persistent postoperative pain and/or stiffness, which may be diagnosed by a combination of a decrease in joint capacity and a decrease in global range of motion (ROM), is considered failed hip arthroscopy.. To assess the failure of a hip joint replacement, consider why the primary procedure failed in the first place.Patients over the age of 40 and those with acetabular dysplasia have a lower . The association of femoral retroversion with slipped capital femoral epiphysis. (3) What is the interobserver reliability and intraobserver reproducibility of these measurement methods? 3. Data is temporarily unavailable. J Bone Joint Surg Am. 1983;54:18-23. Despite this proposed association, little is known about femoral neck version in patients with SCFE. Thus, to assess the full extent of an SCFE deformity, femoral version measurements should consider the position of the displaced epiphysis. Femoral anteversion is a medical condition in which the neck of femur bone leans forward as compared to the rest of the femur. Femoral retroversion (also known as hip retroversion) is a rotational or torsional deformity in which the femur (thighbone) twists backward (outward) in relation to the knee. This yielded a mean side-by side difference of -8 11 (95% CI -11 to -6; p < 0.001) and a higher prevalence of femoral retroversion in hips with SCFE (58% [95% CI 47% to 69%]; p < 0.001) than on the contralateral side (29% [95% CI 19% to 39%]). J Pediatr Orthop. This surgery includes cutting and realigning the femur. Mechanical factors in slipped capital femoral epiphysis. Since the range of femoral version angles was wide, femoral version cannot be predicted in a given hip and must be assessed individually. Accordingly, the mean difference between these two measurement techniques was as high as -19 7 (Table 4). (91% [95% CI 85% to 97%] and 84% [95% CI 76% to 92%], respectively) than for the distal measurement methods of Tomczak et al. Therefore, quantifying femoral version in patients with SCFE should be based on a measurement technique that includes the femoral rotations center. The statistical analysis was performed by a biostatistician (PEM) using SAS version 9.4 (SAS Institute, Cary, NC, USA). Top-view illustrations of excessive femoral retroversion. 15 - 17 Furthermore, it can cause a decrease in the length of the abductor lever arm, 18 posterior extra-articular impingement, 9 and ischiofemoral impingement. Despite increasing evidence that SCFE reflects a rotation of the femoral epiphysis around the epiphyseal tubercle leading to femoral retroversion [23], femoral version has rarely been reported, and the prevalence and degree of femoral retroversion is currently unknown in this population. A turning or tilting backward. We reviewed our institutional database for patients who were treated for SCFE and had undergone pelvic CT scanning for surgical planning. 24. [19] and Reikers et al. However, an excessive femoral retroversion can place stress on hip and knee joints, often leading to joint pain and abnormal wear. (2) These formulae facilitate preparation of computer programs and tables for the routine clinical determination of the anteversion and cervico-diaphyseal angles. This number was chosen based on a power analysis showing that 46 hips would be needed to determine an intraclass correlation coefficient (ICC) greater than 0.80 with an alpha 0.05 and a power of 80%. We compared femoral version angles and the prevalence of femoral retroversion among all five measurement methods. A specialist will observe your . Interobserver reliability and intraobserver reproducibility were high (ICC values > 0.80) for all five measurement methods (Table 6). Isolated open or arthroscopic cam resection has been increasingly proposed as less-invasive options in patients with mild-to-moderate slips, yielding promising short-term results [6, 32, 46]. J Pediatr Orthop. Most proximally (Lee et al. The femoral vein is the major deep vein of the lower extremity. Femoral anteversion describes the inward rotation of the femur bone in the upper leg. 2) and hip ROM [ 32, 33 ]. The condition is usually congenital, meaning children are born with it. Therefore, we asked: (1) Do femoral version and the prevalence of femoral retroversion differ between hips with SCFE and the asymptomatic contralateral side? New York, NY 10021 (1) Do femoral version and the prevalence of femoral retroversion differ between hips with SCFE and the asymptomatic contralateral side? Some abnormalities may resolve spontaneously. Among 10 possible pairwise combinations, we detected differences for 8 pairwise comparisons in hips with SCFE (Table 4). These differences between hips with SCFE and the contralateral side were higher and ranged from -17 11 (95% CI -20 to -15; p < 0.001) based on the method of Tomczak et al. Thereby, we could confirm that leg position was neutral and symetrical (p = 0.29) between the SCFE hip (1 3) and the contralteral hip (1 3) in our study group. Femoral neck version was measured as the orientation of the femoral neck. Femoral neck version, the femoral version angles based on the measurement methods that include the femoral heads center (the methods of Lee et al. 2019;37:1571-1579. SELECTED PROCEEDINGS FROM THE 2020 BERNESE HIP SYMPOSIUM GUEST EDITOR: KLAUS-ARNO SIEBENROCK MD. This procedure may be done for children over age 10 and adults and has a quick and reliable recovery. SCFE and its complications may lead to lifelong disability encompassing pain, gait disturbances, degenerative changes, osteonecrosis and chondrolysis. It also appears to be related to the position of the baby as it grows in the womb. Second, we did not compare femoral version between different severity grades of SCFE because most patients had a severe slip. Various methods to measure femoral version have been described that differ regarding the selection of anatomic landmarks to define the proximal reference axis [19, 30, 35, 36, 44]. An excessive femoral retroversion can place stress on hip and knee joints, often leading to joint pain and abnormal wear. J Pediatr Orthop. The prevalence of femoral retroversion was higher in hips with SCFE for the proximal methods of Lee et al. and Murphy et al. Femoral retroversion may also occur after a physical trauma such as a femur fracture. Relative contribution of epiphyseal tubercle and peripheral cupping to capital femoral epiphysis stability during daily activities. Example Sentences: (1) The measurement mean for anteversion among these specimens was 7.4 degrees with a range from -10.8 degrees (retroversion) to 22.1 degrees. External Tibial Torsion Much like internal tibial torsion, this condition improves in most children before or around the age of 10. The hip joint and psoas muscle lie directly deep to the femoral . In hips with SCFE, we found excellent agreement (intraclass correlation coefficient [ICC] > 0.80) for intraobserver reproducibility (reader 1, ICC 0.93 to 0.96) and interobserver reliability (ICC 0.95 to 0.98) for all five measurement methods. The prevalence of femoral retroversion (< 0) was compared using a chi-square test. Diagnosing femoral retroversion can sometimes be difficult, as the common positioning used for X-ray imaging may not reveal a rotation in the femoral neck. In some cases, a minimally invasive version of a femoral osteotomy may be performed. Femoral retroversion can also occur after a physical trauma such as a femur fracture. J Child Orthop. 5 Femoral version, also referred to as femoral torsion, is another morphologic variable being investigated. My doctors would not treat me unless I had surgery to fix the retroversion. 3). Hip dysplasia. [35]. Thus, a normal rotation between the hip and the knee is established, correcting the torsional deformity. First, we included patients who had previous in situ fixation and presented with a symptomatic SCFE deformity as well as patients who had not undergone any surgical treatment for SCFE. Also called hip anteversion, femoral anteversion is a forward (inward) rotation in the femur (thighbone), which connects to the pelvis to form the hip joint. Osteotomy through the lesser trochanter for slipped capital femoral epiphysis. to -22 13 (95% CI -25 to -19; p < 0.001) according to the method of Murphy et al. 41. Femoral anteversion is an inward twisting of the thigh bone, also known as the femur (the bone that is located between the hip and the knee). and Reikers et al.) The classic radiographic parameters to characterize femoroacetabular impingement secondary to SCFE include the slip angle and alpha angle measured on radiographs [28]. Basheer SZ, Cooper AP, Maheshwari R, Balakumar B, Madan S. Arthroscopic treatment of femoroacetabular impingement following slipped capital femoral epiphysis. Kiapour AM, Kiapour A, Maranho DA, Kim Y-J, Novais EN. Retroversion refers to an abnormal backward rotation of the hip relative to the knee. 2019:47:3120-3132. POA Help "Present On Admission" is defined as present at the time the order for inpatient admission occurs conditions that develop during an outpatient encounter, including emergency department, observation, or outpatient surgery, are considered POA Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. Femoral version in acute slipped capital femoral epiphysis. Murphy SB, Simon SR, Kijewski PK, Wilkinson RH, Griscom NT. Hello friends, thankyou for watching my video, I am Physiotherapist with masters degree and working as Associate Professor in Mangalore.I love to teach and p. The condition is usually congenital, meaning children are born with it. 40. Hesper T, Bixby SD, Maranho DA, Miller P, Kim YJ, Novais EN. Please try again soon. 36. The mean femoral neck version was lower on the SCFE side than on the contralateral side (-2 13 versus 7 11; p < 0.001) (Table 3). Int J Numer Method Biomed Eng. For those who do not grow out of it, a mild femoral retroversion may not cause any significant issues. 27. However, future studies are needed to investigate the value of different measurement methods in predicting the surgical outcome in patients with SCFE undergoing different procedures. 2017;6:472-480. Wolters Kluwer Health The prevalence of femoral retroversion was high in patients with SCFE and increased when using proximal anatomic landmarks. Femoral neck version was measured as the orientation of the femoral neck. Femoral version angles did not differ between hips with and without previous in situ pinning for any of the five measurement methods (for example, Lee et al. 1973;55:1218-1224. The definition of the proximal reference axis differs among the five methods. The mean overall femoral version angles increased for hips with SCFE using more-distal landmarks compared with more-proximal landmarks. In our study, the prevalence of femoral retroversion was higher (60%) in hips with SCFE and the mean femoral version was decreased (-4 16) using the same method described by Murphy et al. Purpose. Femoral Retroversion. He may also order an X-ray or CT scan to look for possible deformities. 43. Lerch TD, Novais EN, Schmaranzer F, et al. At the time of CT, the femoral growth plate of the asymptomatic contralateral side was already closed in 42% (33 of 79) of patients. The institution of one or more of the authors (FS) has received, during the study period, funding from the Swiss National Science Foundation, Switzerland, Grant No. Fourth, although we compared our observations in SCFE hips with the unaffected contralateral side, we note that these hips may not reflect a normal population. Mechanical risk factors for SCFE include rapid growth spurts, femoral retroversion, and femoral neck shaft angle. 1986;68:1000-1007. Clin Orthop Relat Res. In addition, we observed increasing femoral version angles with selection of more-distal landmarks in SCFE hips regardless of whether or not previous in situ pinning had been performed (Table 5). This means thehip is twisted backward (posteriorly) in relation to the knee. Conclusion: This yielded a mean side-by side difference of -8 11 (95% CI -11 to -6; p < 0.001) and a higher prevalence of femoral retroversion in hips with SCFE (58% [95% CI 47% to 69%]; p < 0.001) than on the contralateral side (29% [95% CI 19% to 39%]). These differences ranged from -17 11 (95% CI -20 to -15; p < 0.001) based on Tomczak et al.s [44] method to -22 13 (95% CI -25 to -19; p < 0.001) when applying Murphy et al.s [30] method (Fig. Czech. For patients with SCFE deformity, this included the decision to perform isolated cam resection, intertrochanteric flexion-derotation osteotomy with or without cam resection, or a modified Dunn procedure in patients with an open femoral growth plate. For information on cookies and how you can disable them visit our Privacy and Cookie Policy. Thus, the hip possesses three degrees of freedom of motion with three correspondingly arranged, mutually . The exact cause of femoral retroversion is unknown. The prevalence of femoral retroversion was high in patients with SCFE and increased when using proximal anatomic landmarks. Femoral Retroversion. 3). In this position, the femoral head is not positioned normally in the hip joint. The physician may also order an X-ray or CT scan to look for possible deformities. Previous studies only included the femoral neck version and not the center of the femoral head as a reference [15, 42]. and most-distal methods (Tomczak et al. Dawes B, Jaremko JL, Balakumar J. Radiographic assessment of bone remodelling in slipped upper femoral epiphyses using Kleins line and the angle of femoral-acetabular impingement: a retrospective review. Doing so may better inform surgeons as they contemplate when to use isolated offset correction or perform an addional femoral osteotomy for SCFE correction based on the severity of the slip and the rotational deformity. 2019 May;477(5):1073-1083. doi: 10.1097/CORR.0000000000000610. Schmaranzer F, Lerch TD, Siebenrock KA, Tannast M, Steppacher SD. 2018;46:122-134. The right leg is 1.5 cm longer than normal. Eur Radiol. Clin Orthop Relat Res. The present study evaluated, using an integrated vascular approach, changes in structure and function of the common carotid and femoral arteries (CCA and CFA) after prolonged head-down tilt bed rest (HDTBR). All five methods were compared side-by-side (involved versus uninvolved hip), and comparisons among all five methods were performed using paired t-tests. Arthroscopy. The I-bars represent the corresponding 95% CI. The data table on the chart reports the mean SD. Combined Imhauser osteotomy and osteochondroplasty in slipped capital femoral epiphysis through surgical hip dislocation approach. [1] Femoral anteversion is the angle between the femoral neck and femoral shaft, indicating the degree of torsion of the femur. n. 1. The Lisbon agreement on femoroacetabular impingement imaging-part 1: overview. 23. Clin Orthop Relat Res. Fishkin Z, Armstrong DG, Shah H, Patra A, Mihalko WM. External tibial torsion. Femoral anteversion occurs in up to 10 percent of children. A labral tear, subspine and intertrochanteric impingement and femoral retroversion. to -22 13 (95% CI -25 to -19; p < 0.001) according to the method of Murphy et al. . Coxa valga and antetorta increases differences among different femoral version measurements : potential implications for derotational femoral osteotomy planning. The torsional deformity is corrected by re-establishing the normal rotation between the hip and the knee. During the period in question, the general indication for obtaining a CT scan was to define the surgical strategy based on the assessment of deformity severity in patients with newly diagnosed SCFE or with previous in situ fixation. Pain in the hip has been present for over 1 year, limiting activities. She was treated with an open reduction and bracing in infancy. However, in some cases, this may be difficult to identify, especially if femoral retroversion is combined with a separate rotation deformity such as tibial torsion. [30]; range, -39 to 61) using different measurement methods (Table 3). How Common Is Femoral Retroversion and How Is it Affected by Different Measurement Methods in Unilateral Slipped Capital Femoral Epiphysis? Please enable it to take advantage of the complete set of features! 8600 Rockville Pike This surgery includes cutting and realigning the femur. 2014;30:1314-1325. Femorln retroverze. [30] (47% [95% CI 36% to 58%] and 60% [95% CI 49% to 71%], respectively [all p < 0.001]) (Table 3). and most-distal methods (Tomczak et al. Symptoms of femoral retroversion may include: If femoral retroversion is suspected, a doctor will do a physical examination of the legs and hips in addition to a thorough medical, developmental and family history. This surgery includes cutting and realigning the femur. Galbraith RT, Gelberman RH, Hajek PC, et al. This condition can affect patients of all ages and leads to abnormal stress in the low back, hip and knee and abnormal gait. Bone Jt Open. 2015;31:247-253. January 31, 2022 . 4. 6. In these situations, a surgical procedure known as a femoral osteotomy may be used. This study has several limitations. The impingement is accentuated if there is concomitant acetabular retroversion, a cam or pincer lesion, coxa profunda, or protrusio. To date, the best treatment strategy in patients with symptomatic SCFE deformity is not known because of a lack of comparative studies with long-term follow-up [2, 47]. The ICC was graded as slight agreement for 0.20, 0.21 to 0.40 was graded as fair, 0.41 to 0.60 was graded as moderate, and more than 0.80 was graded as almost-perfect agreement [29]. Interrater reliability was assessed across raters using an ICC (2,2) model and intrarater reliability was assessed using an ICC (3,1) model [39]. J Child Orthop. Because there is a wide range of femoral anteversion values both in the healthy population and in patients with femoroacetabular impingement, it is recommended that femoral anteversion is assessed individually in all patients with suspected femoroacetabular impingement. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. We detected mean differences ranging from -19 to 4 (all p < 0.005) for 8 of 10 pairwise comparisons in hips with SCFE. Femoral version is a relevant measurement that affects hip range of motion and pathology. This is because opposite, incorrect rotations of the femur and tibia often leave the feet parallel during walking, which often makes the misalignment of the hips and knees go unnoticed. Tnnis D, Heinecke A. Acetabular and femoral anteversion: relationship with osteoarthritis of the hip. femoroacetabular impingement. Loder RT, Aronson DD, Greenfield ML. Several factors, including obesity and a decreased femoral anteversion angle, have been associated with the development of slipped capital femoral epiphysis (SCFE) [31]. The mean age at the time of CT was 15 4 years. Prevalence of femoral and acetabular version abnormalities in patients with symptomatic hip disease: a controlled study of 538 hips. Southwick WO. Is femoral Retroversion a disability? We showed that femoral neck version is asymmetrically decreased in unilateral SCFE, and that differences increase when including the femoral head's center. 519 East 72nd St., Suite 204 Historically, severe and moderate SCFE deformities leading to symptomatic femoroacetabular impingement have been treated with an extraarticular approach by means of an intertrochanteric osteotomy [16, 41]. Methods: If a thickened medial plica is suspected, this can be palpated over the medial femoral condyle with the knee at 30. [35] (91% [95% CI 85% to 97%] and 84% [95% CI 76% to 92%], respectively) than for the distal measurement methods of Tomczak et al. Limb Lengthening and Complex Reconstruction Service, out-toeing or "duck walk" walking with the foot pointed outward instead of straight ahead. All ICMJE Conflict of Interest Forms for authors and Clinical Orthopaedics and Related Research editors and board members are on file with the publication and can be viewed on request. Wylie JD, McClincy MP, Uppal N, et al. The ischiofemoral distance was evaluated for patients with increased FV on preoperative MRI and was lower (17 5 mm, range 12-25) compared to the reported normal ischiofemoral distance [ 46] of 30.6 mm. Novais EN, Hosseinzadeh S, Emami SA, Maranho DA, Kim YJ, Kiapour AM. If the individual also has a separate rotational bone deformity such as internal tibial torsion an inward rotation of the tibia (shinbone) then femoral retroversion becomes even more difficult to diagnose. Federal government websites often end in .gov or .mil. For more information, please refer to our Privacy Policy. Compression fixation after biplane intertrochanteric osteotomy for slipped capital femoral epiphysis. In many cases, the child may grow out of it. Common complications include secondary arthrosis and. At birth the angle of torsion is 30-35 degrees and the femoral head faces anteriorly in the acetabulum. femoral retroversion synonyms, femoral retroversion pronunciation, femoral retroversion translation, English dictionary definition of femoral retroversion. Based on these findings, we believe it is worthwhile to add evaluation of femoral version to the diagnostic workup of children with SCFE. Clin Orthop Relat Res. Further measurement methods included the femoral head's center and differed regarding the level of landmarks for the proximal femoral reference axis. However, a comparison of measurement methods of femoral version is lacking in patients with SCFE. A subset of patients was measured twice by two readers (FS, JRK) to assess intraobserver reproducibility and interobserver reliability. Clipboard, Search History, and several other advanced features are temporarily unavailable. 2). 2013;95:e341-348. This yielded a mean side-by-side difference of -8 11 (95% CI -11 to -6; p < 0.001) and a higher prevalence of femoral retroversion on the SCFE side of 58% (95% CI 47% to 69%) than on the contralateral side (29% [95% CI 19% to 39%]; p < 0.001) (Table 3). For the diagnosis of this condition, conventional AP pelvic radiographs may represent a reliable, easily available diagnostic modality as they can be obtained with a reproducible technique allowing the anterior and posterior acetabular rims to be visible for assessment. A Type I error rate of 5% was used. In patients with implant failure following in situ fixation, this included assessment of the femoral growth plate for planning of revision in situ fixation. and Murphy et al. J Bone Joint Surg Am. Am J Sports Med. The method of Murphy et al. J Pediatr Orthop B. From proximal to distal, this included Lee et al.s [19] method, modified to include the femoral heads center with the second landmark defined as the first image on which the connection between the femoral neck and the grater trochanter is visible (Fig. Torsional deformity can also occur after a fracture, if a broken bone heals with incorrectly (called malunion). This is the story of her diagnosis, operations and recovery to date: Hi I'm Elise and I live in Northern Ireland. 1988;8:385-388. Clin Orthop Relat Res. AJR Am J Roentgenol. Clinical features include an abnormal gait and pain with prolonged weight-bearing. Osteotomy to correct the alignment is rarely needed. In the axial HASTE images over the proximal and distal femur a femoral retroversion can be seen, i.e. 212-606-1415| 212-606-1550| 212-606-1637 | 212-606-1097. The retroversion was causing a minor curvature in my lumbar spine, tendinosis in my hamstring, and labral tears. Lee YS, Oh SH, Seon JK, Song EK, Yoon TR. This procedure may be done for children over age 10 and adults and has a quick and reliable recovery. This may also make the legs look bowed. The method of Reikers et al. The human hip is a modified spherical (ball-and-socket) joint. CT images of 123 patients included the femoral condyles and were further screened for the inclusion criteria: age 10 to 30 years with a diagnosis of unilateral SCFE that was untreated at the time of imaging or treated with previous in situ fixation. Because the epiphysis is displaced posteroinferiorly in patients with SCFE, such measurements may underestimate the severity of the deformity. He may also order an. This underlines the complex, multifactorial pathogenesis of SCFE, which further includes endocrine disorders [26] and altered epiphyseal orientation [24] and morphology [17, 23] and warrants further investigation. 2020:296:381-390. Femoral retroversion often runs in families, which may indicate that some children have a higher risk of being born with this condition. Femoral retroversion is often a congenital condition, meaning children are born with it. 2021 May 1;479(5):935-944. doi: 10.1097/CORR.0000000000001590. The Hip Disability and Osteoarthritis Outcome Score (HOOS) (Klassbo et al., 2003; Nilsdotter et al., 2003), was administered to determine level of hip-specific functional disability in the CHJP group. Femoral retroversion is a condition in which the femoral neck is rotated backward in relation to the femoral shaft. J Bone Joint Surg Am. What is femoral anteversion? Abstract Slipped capital femoral epiphysiolysis (SCFE) may result in femoroacetabular. Measurement on axial HASTE images (proximal and distal femur): [35]; range, -53 to 15) to 100 (Murphy et al. And if left untreated into adolescence, these abnormal femoral rotations can also contribute to the degeneration or arthritis of the hip. Out-toeing is the common name used for a condition known as femoral retroversion. 25. and Tomczak et al. MR imaging measurement of the femoral antetorsional angle as a new technique: comparison with CT in children and adults. Studies using this imaging modality to measure femoral version are limited by long acquisition times that are prone to patient malpositioning [15, 42]. Furthermore, the prevalence of actual femoral retroversion and the effect of different measurement methods on femoral version angles has yet to be studied in SCFE. Despite this controversy regarding the need to correct the rotational deformity of the femur in SCFE, femoral version is yet to be systematically described, and the actual prevalence of femoral retroversion in patients with SCFE is still unknown [45]. Right: Most patients with excessive hip retroversion compensate by walking out-toed. and Murphy et al.). Lerch TD, Boschung A, Todorski IAS, et al. Thus, to assess the full extent of an SCFE deformity, femoral version measurements should consider the position of the displaced epiphysis. Shrout PE, Fleiss JL. 20. We found that femoral neck version is asymmetrically decreased by -8 in unilateral hips with SCFE compared with contralateral hips. Most proximally (Lee et al. Initial diagnosis of unilateral SCFE was based on an absence of radiographic signs of SCFE and of pain at clinical examination. Femoral retroversion is common in early infancy and is caused by external rotation contracture of the hip secondary to intrauterine packing. Chadayammuri V, Garabekyan T, Bedi A, et al. Femoral anteversion causes the child's knees and feet to turn inward, or have what is also known as a "pigeon-toed" appearance. Schmaranzer F, Todorski IAS, Lerch TD, Schwab J, Cullmann-Bastian J, Tannast M. Intra-articular lesions: imaging and surgical correlation. Seventy-two percent of the patients in our cohort were overweight or obese. In hips with SCFE, we found excellent agreement (intraclass correlation coefficient [ICC] > 0.80) for intraobserver reproducibility (reader 1, ICC 0.93 to 0.96) and interobserver reliability (ICC 0.95 to 0.98) for all five measurement methods. Femoral anteversion can occur in one or both legs. 3). Clinical Orthopaedics and Related Research, Get new journal Tables of Contents sent right to your email inbox, The Association of Bone and Joint Surgeons, https://journals.lww.com/clinorthop/Fulltext/2019/05000/Differences_in_Femoral_Torsion_Among_Various.26.aspx. Many children born with femoral retroversion grow out of it. Furthermore, the sample sizes in these studies that compared femoral version between the affected and unaffected hip in patients with unilateral SCFE were small. Differences in Femoral Torsion Among Various Measurement Methods Increase in Hips With Excessive Femoral Torsion. Case reports: acetabular damage after mild slipped capital femoral epiphysis. The hip joint is where the femoral head (the top of the femur) meets the pelvis. grip" deformity) and relative retroversion of the femoral head were dened as the cause of cam-type FAI, with worse long-term clinical and radiographic results. 2013;27:308-311. 28. Causes of the Anteversion and Retroversion of the Hip Bali NS, Harrison JO, Bache CE. NCI CPTC Antibody Characterization Program. J Bone Joint Surg Am. 2009;467:724-731. A pathological increase in angle of torsion is called femoral anteversion, and a pathological decrease in the angle or reversal of torsion is known as femoral retroversion. Varus derotation intertrochanteric osteotomy with femoral retroversion. J Pediatr Orthop. Japanese. Bob & Brad 3.9M views 5 years ago. In other words the knee is excessively twisted inward relative to the hip. In some cases, hip/femoral retroversion may be combined with a separate torsional deformity, such as a rotation in the tibia. Based on these findings, we believe it is worthwhile to add evaluation of femoral version to the diagnostic workup of children with SCFE. To rule out this potential bias, we measured leg abduction angle on coronal scout CT views between a line connecting the femoral head with the center of the femoral condyle relative to the neutral line connecting the tip of the coccyx with the pubic symphysis. Since the range of femoral version angles was wide, femoral version cannot be predicted in a given hip and must be assessed individually. Remodelling of femoral head-neck junction in slipped capital femoral epiphysis: a multicentre study. Although external rotation of the proximal femur relative to the femoral condyles (that is, femoral retroversion) has been linked with the onset of SCFE and has been proposed to result from a rotation of the femoral epiphysis around the epiphyseal tubercle leading to femoral retroversion, femoral version has rarely been described in SCFE [24, 31]. More distally, the pes anserinus bursa should be palpated for tenderness typical of pes . Patellofemoral joint pain is a very common knee problem physical therapists see in the clinic. Madhuri V, Arora SK, Dutt V. Slipped capital femoral epiphysis associated with vitamin D deficiency: a series of 15 cases. Femoral Retroversion This condition rarely causes long-term problems, however, in some, it may predispose to slipped capital femoral epiphysis (SCFE). Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. Tomczak et al.s [44] method uses the center of the base of the greater trochanter as a landmark. 17. 8. . (1) Do femoral version and the prevalence of femoral retroversion differ between hips with SCFE and the asymptomatic contralateral side? The femur bone is cut through a portal and an intramedullary rod is inserted into the marrow cavity of the bone. This work was performed at the Department of Orthopaedic Surgery, Boston Childrens Hospital, Harvard Medical School, Boston, MA, USA. 2014;96:1441-1448. Request PDF | On Apr 6, 2015, Henry Knipe and others published Femoral retroversion | Find, read and cite all the research you need on ResearchGate Furthermore, we found that SCFE does not necessarily lead to femoral retroversion, and that femoral version angles differ widely, ranging from 68 (Reikers et al. The remaining four measurement methods use the femoral heads center as the most proximal reference. In this type of surgery, the femur bone is cut through a portal and an intramedullary rod is inserted into the marrow cavity of the bone. Clin Orthop Relat Res. Radiology. 18. This is comparable to the femoral neck version of the contralateral hips in our study population. 1956;88:3-41. A modified Imhuser osteotomy: an assessment of the addition of an open femoral neck osteoplasty. 2019;477:1073-1083. Since the range of femoral version angles is wide, no general prediction regarding the degree of rotational deformity can be made on an individual basis. This condition can affect patients of all ages and leads to abnormal stress in the low back, hip and knee, as well as an abnormal gait (walking stance). 2012;28:965-971. All CT scans including axial images covering the osseous pelvis and distal femoral condyles were used to measure femoral version. See this image and copyright information in PMC. [30] uses the center superior to the lesser trochanter at the base of the femoral neck as a landmark. Z Orthop Ihre Grenzgeb. "Of key note on the 3D studies," says Dr. Kamath "is the low femoral version 2.2 degrees, which is relative retroversion of the femur, when compared to normative female populations of this age." Her diagnosis? Proximal femoral physis shear in slipped capital femoral epiphysis--a finite element study. (2) How do the mean femoral version angles and the prevalence of femoral retroversion change depending on the measurement method used? Intraclass correlations: uses in assessing rater reliability. 13. 2006;26:291-294. Approach to the hip for SCFE: the North American perspective. This site needs JavaScript to work properly. However, in some cases, this may be difficult to identify, especially if femoral retroversion is combined with a separate rotation deformity such as tibial torsion. The effect of femoral and acetabular version on clinical outcomes after arthroscopic femoroacetabular impingement surgery. These differences increased when including the femoral heads center as a reference. (2) How do the mean femoral version angles and the prevalence of femoral retroversion change depending on the measurement method used? Femoral retroversion is common in newborns because of contracture of the hip from intrauterine positioning. 2. Clinical Orthopaedics and Related Research479(5):947-959, May 2021. Diagnosing femoral retroversion can sometimes be difficult, as the common positioning for X-ray imaging may not reveal a rotation in the femoral neck. Using the four alternative measurement techniques that are based on the center of the femoral head as a proximal reference, the mean differences between the affected and contralateral side were higher. Differences in femoral torsion among various measurement methods increase in hips with excessive femoral torsion. [30]) when including the femoral heads center as a reference to account for displacement of the epiphysis (Fig. Retroversion refers to an abnormal backward rotation of the hip relative to the knee. Paired t-tests including Bonferroni corrections for repeated measurements were performed for comparison between the mean femoral version angles. Furthermore, the prevalence of actual femoral retroversion and the effect of different measurement methods has yet to be studied in SCFE. Arthroscopy. [19] and Reikers et al. The first symptom of femoral retroversion is usually a visual recognition of the rotated femur. Exclusion criteria were bilateral SCFE in 31% (38 patients), any contralateral hip condition in 1% (one patient), and previous femoral osteotomies in 4% (five patients). Ethical approval for this study was obtained from the institutional review board of Boston Childrens Hospital (protocol number IRB-P00018761). 12. In many cases, the abnormal rotation of the femur develops while the fetus is growing in the womb. Fabricant PD, Bedi A, De La Torre K, Kelly BT. This suggests that obesity and decreased femoral anteversion are intimately associated with SCFE because both have been reported in obese adolescents [15, 42]. Clinical outcomes after arthroscopic psoas lengthening: the effect of femoral version. Bone Joint J. 1967;49:807-835. Femoral retroversion can occur in one or both legs. Clin Orthop Relat Res. 19. Acta Orthop Scand. Define femoral retroversion. In our institution, the method described by Murphy et al. It becomes apparent as the child starts to stand or cruise between 6 and 9 months. Clin Orthop Relat Res. What is the prevalence of cam deformity after prophylactic pinning of the contralateral asymptomatic hip in unilateral slipped capital femoral epiphysis? The mean age was 59.5 12 years and the . 2019;43:2375-2382. and Tomczak et al. Background: Although femoral retroversion has been linked to the onset of slipped capital femoral epiphysis (SCFE), and may result from a rotation of the femoral epiphysis around the epiphyseal tubercle leading to femoral retroversion, femoral version has rarely been described in patients with SCFE. All ICMJE Conflict of Interest Forms for authors and Clinical Orthopaedics and Related Research editors and board members are on file with the publication and can be viewed on request. 2013;95:851-854. The normal angle of neck of the femur and the transverse angle of the femoral condyles is 8-12 degrees anterior in the average adult. Subcapital osteotomy of the femoral neck for patients with healed slipped capital femoral epiphysis. 1979;86:420-428. 19 Finally, excessive femoral anteversion may [30], a recent study reported a prevalence of femoral retroversion (< 0) of 5% and a mean femoral version of 19 14 in a cohort of 538 hips with femoroacetabular impingement, developmental dysplasia of the hip, and Perthes disease [22]. Based on these findings, we believe it is worthwhile to add evaluation of femoral version to the diagnostic workup of children with SCFE. Schmaranzer F, Lerch TD, Siebenrock KA, Tannast M, Steppacher SD. Left: Position of a retroverted femoral head with the foot facing straight forward. However, an excessive femoral retroversion can place stress on hip and knee joints, often leading to joint pain and abnormal wear. Femoroacetabular impingement patients with decreased femoral version have different impingement locations and intra- and extraarticular anterior subspine FAI on 3D-CT-based impingement simulation: implications for hip arthroscopy. Doing so may better inform surgeons as they contemplate when to use isolated offset correction or to perform an additional femoral osteotomy for SCFE correction based on the severity of the slip and the rotational deformity. We also compared isolated femoral neck version with aligning the orientation of the femoral neck with the femoral head center to define the proximal reference, as described by Reikers et al. Significantly increased femoral anteversion affects the rotational profile of the lower extremity, leading to increased internal rotation. This graph shows a comparison of the different methods to measure femoral version, MeSH Of the 754 patients diagnosed with SCFE between 2000 and 2017, 172 patients had undergone pelvic CT scans. 2012;470:3432-3438. A study of children in Michigan. A preoperative 3D-CT-scan was performed for 3D simulation of hip impingement ( Fig. Depending on the measurement method, femoral version angles vary considerably in hips with high femoral anteversion [37]. Balakumar B, Flatt E, Madan S. Moderate and severe SCFE (slipped capital femoral epiphysis) arthroscopic osteoplasty vs open neck osteotomy-a retrospective analysis of results. [] reported an association of SCFE and femoral retroversion.More recently, many studies have shown an association . CORR Insights: How Common Is Femoral Retroversion and How Is it Affected by Different Measurement Methods in Unilateral Slipped Capital Femoral Epiphysis? [44]) (Table 3). From proximal to distal, this included the most-proximal methods (Lee et al. Accordingly, there was a mean difference of -16 6 (95% CI -17 to -15; p < 0.001) between the methods of Lee et al. Symptoms of femoral retroversion usually begin with the visual recognition of the rotated femur. BMC Health Serv Res. 30. The prevalence of femoral retroversion (< 0) was compared using a chi-square test. [30] (Table 3). CORR Insights: How Common Is Femoral Retroversion and How Is it Affected by Different Measurement Methods in Unilateral Slipped Capital Femoral Epiphysis? However, Koerner et al. 2013;37:2331-2336. Out-toeing or duck walk walking with the foot pointed outward instead of straight ahead, If the doctor suspects a femoral retroversion, he will conduct a physical examination of the legs and hips in addition to a thorough medical, developmental and family history. 2018;38(suppl 1):S5-S12. A subset of patients was measured twice by the first observer and by a second orthopaedic resident (2 years of experience) to assess intraobserver reproducibility and interobserver reliability; for this assessment, we used intraclass correlation coefficients. and Reikers et al. Femoral antetorsion was significantly higher in patients with pincer-type FAI than in those with cam-type FAI for reader 1 (18.3 9.8 vs 10.0 9.1, P = .02) and reader 2 (18.7 10.5 vs 11.6 8.8, P = .04). Please try after some time. Before imaging analyses, both observers were trained using a different sample of 20 CT scans with SCFE by a senior orthopaedic hip surgeon (ENN, 17 years of experience). 6 It is the angular From birth to 6 yrs. 2019;477:1111-1122. We performed a retrospective, controlled, single-center study at a tertiary pediatric care center and included patients with SCFE treated between 2000 and 2017. Craig's test is a passive test that is used to measure femoral anteversion or forward torsion of the femoral neck. The condition is usually congenital, meaning children are born with it. Imhauser G. Pathogenesis and therapy of hip dislocation in youth [in German]. Forty-eight percent (38 of 79 patients) were male, and 72% (57 of 79) were overweight (13 patients [17%] with a BMI between the 85th and 95th percentiles) or obese (44 patients [56%] with a BMI above the 95th percentile). The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. (47% [95% CI 36% to 58%] and 60% [95% CI 49% to 71%], respectively [all p < 0.001]). To facilitate communication among physicians and for the design of future studies, we recommend consistently reporting the applied measurement technique. A 10-year minimum followup study. 38. In our cohort, femoral neck version was asymmetrically decreased (-2 13 versus 7 11) and the prevalence of femoral retroversion was higher (58% versus 29%) in hips with SCFE than in the healthy contralateral side (Table 3). Time from SCFE diagnosis to CT was 1.8 2.5 years (Table 1). Accordingly, the methods of Lee et al. 2021 May 1;479(5):960-961. doi: 10.1097/CORR.0000000000001704. In hips with SCFE, we found excellent agreement (ICC > 0.80) for intraobserver reproducibility for reader 1 (ICC range 0.93 to 0.96), for reader 2 (ICC range 0.97 to 0.99), and interobserver reliability (ICC range 0.95 to 0.98) for all five measurement methods (Table 6). [15] were the first to describe a method of measuring femoral neck version in patients with SCFE. This website uses cookies. J Orthop Res. 2012 Dec;470(12):3432-8. doi: 10.1007/s11999-012-2452-y. 1993;75:1141-1147. Arthroscopic treatment of mild to moderate deformity after slipped capital femoral epiphysis: intra-operative findings and functional outcomes. However, among the remaining measurement methods, it is not possible to recommend one measurement method over another based on our findings. may email you for journal alerts and information, but is committed 44. (3) What is the interobserver reliability and intraobserver reproducibility of these measurement methods? In anatomy, the word "version" refers to the angle or rotation of all or part of an organ, bone or other structure in the body, relative to other structures in the body. The data table on the chart reports the mean SD. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. [19] and Tomczak et al. During the period in question, the general indication for obtaining a CT scan was to define the surgical strategy based on the assessment of deformity severity in patients with newly diagnosed SCFE or with previous in situ fixation. The minimum slice thickness was 2 mm. Conclusion Femoral antetorsion can be measured rapidly and with good reproducibility with MR imaging. Femoral version of the general population: does normal vary by gender or ethnicity? The doctor will also observe the patients gait (manner of walking) to look for signs of out-toeing or gait compensation. Femoral anteversion is usually most noticeable in children between the ages of 4 and 6. Retrotorsion is a pathologic decrease in the torsion angle; ie it is less than 8 degrees. (47% [95% CI 36% to 58%] and 60% [95% CI 49% to 71%], respectively [all p < 0.001]). When comparing hips with SCFE with the unaffected contralateral side, we found higher differences (range of mean differences -22 to -17) with measurements that consider the femoral heads center than for the method of femoral neck version (mean difference -8) (Fig. It has been reported that some degree of remodeling of the femoral head-neck junction can be expected after fixation of the epiphysis over time [1, 9]. Schmaranzer, Florian MD, PhD; Kallini, Jennifer R. MD; Ferrer, Mariana G. MD; Miller, Patricia E. MSc; Wylie, James D. MD; Kim, Young-Jo MD, PhD; Novais, Eduardo N. MD, F. Schmaranzer, J. R. Kallini, M. G. Ferrer, P. E. Miller, J. D. Wylie, Y-J. Femoral version by measurement method and by side (affected versus contralateral) was summarized using the mean, SD, and 95% confidence interval. 34. The mean femoral neck version was lower in hips with SCFE than in the contralateral side (-2 13 versus 7 11; p < 0.001). However, severe cases require surgical correction. Retroversion refers to an abnormal backward rotation of the hip relative to the knee. In anatomy, the word version refers to the angle or rotation of all or part of an organ, bone or other structure in the body, relative to other structures in the body. 2. To facilitate communication among physicians and for the design of future studies, we recommend consistently reporting the applied measurement technique. Background: Faldini C, Brunello M, Pilla F, Geraci G, Stefanini N, Tassinari L, Di Martino A. Femoral Head Autograft to Manage Acetabular Bone Loss Defects in THA for Crowe III Hips by DAA: Retrospective Study and Surgical Technique. Symptoms of femoral retroversion may include: If the doctor suspects a femoral retroversion, he will conduct a physical examination of the legs and hips in addition to a thorough medical, developmental and family history. Any treatment of my symptoms was going to be ineffective due to the alignment still being off. Contact Dr. Jarman, DPM Phoenix Podiatrist. , and. The articular cartilage is intact. Among these, the greatest differences were between the most-proximal methods and the more-distal methods, with a mean difference of -19 7 (95% CI -21 to -18; p < 0.001), comparing the methods of Lee et al. Novais EN, Millis MB. 3). A subset of patients was measured twice by the first obsever as well as by a second orthopaedic resident (JRK, 2 years of experience) to assess intraobserver reproducibility and interobserver reliability. 2020;14:190-200. Because the lower part of the femur is connected to the knee, this also means that the knee is twisted outward relative to the hip. The aim of the current study was to obtain precise normal values of the femoral anteversion angle using computed tomography on cadavers of mature dogs with normal hip joints of . I've recently turned 18 and I want to share my experience of femoral retroversion. Measurement of femoral version has been recommended in patients eligible for hip preservation surgery [27, 38] because of the high prevalence of abnormal femoral version in patients with hip pain [21, 22] and its effect on ROM [8, 20] and the outcome of surgery for femoroacetabular impingement [11, 12]. Thus, this should not jeopardize the results of our study to a relevant degree. Reduced femoral neck version is more common in adolescents with obesity than in those without obesity [14]. In these situations, a surgical procedure known as a. may be used. 5, 9, 11 It is diagnosed when the feet of a prewalking child are . If the individual also has a separate rotational bone deformity such as internal tibial torsion an inward rotation of the tibia (shinbone) then femoral retroversion becomes even more difficult to diagnose. This can cause pain and abnormal force in the hip and can lead to degeneration and arthritis. Liu RW, Fraley SM, Morris WZ, Cooperman DR. Validity and clinical consequences of a rotational mechanism for slipped capital femoral epiphysis. Bone Joint Res. 2017;21:487-506. Clin Orthop Relat Res. the axis of the femoral neck is oriented more posteriorly than the distal reference line connecting the dorsal border of the femoral condyles. [18] reported normal femoral neck version of 8.8 9.7 in 328 hips without radiographic signs of osteoarthritis. Bethesda, MD 20894, Web Policies After applying prespecified inclusion and exclusion criteria, we included 79 patients. Liu RW, Armstrong DG, Levine AD, Gilmore A, Thompson GH, Cooperman DR. An anatomic study of the epiphyseal tubercle and its importance in the pathogenesis of slipped capital femoral epiphysis. Routinely measuring femoral version might help surgeons better identify which part of an abnormal femur (cam deformity and/or externally rotated femur) should be corrected. We performed further subgroup analysis between hips with and without previous in situ fixation to assess whether femoral version measurements might be affected by postoperative remodeling or potential previous partial reduction. and Murphy et al.). Further measurement methods included the femoral heads center and differed regarding the level of landmarks for the proximal femoral reference axis. 37. Because the lower part of the femur is connected to the knee, this also means that the knee is twisted outward relative to the hip. Pritchett JW, Perdue KD. Acetabular retroversion has been proposed to contribute to the development of osteoarthritis of the hip. Disclaimer, National Library of Medicine FOIA Stanitski CL, Woo R, Stanitski DF. Using the method of Murphy et al. femoral anteversion decreases on average 25 degrees during this time as well Presentation Symptoms anterior knee pain caused by patellofemoral malalignment Physical Exam thigh-foot axis measurement best way to evaluate tibial torsion average during infancy is 5 degrees internal rotation, that slowly derotates In some cases, hip/femoral retroversion may be combined with a separate torsional deformity, such as a rotation in the tibia. They reported femoral neck angles of -0.7 7.4 in 13 patients (10 with obesity) with acute SCFE compared with angles of 6.3 8.2 in the uninvolved side [15]. External rotation contracture of the hip. To rule out any subsequent SCFE of the contralateral hip, we further assessed the status of the femoral growth plate at the time of CT and at latest follow-up. More specifically, the prevalence of femoral retroversion was higher in hips with SCFE for the proximal methods of Lee et al. The I-bars represent the corresponding 95% CI. Femoral anteversion. Schmaranzer F, Meier MK, Lerch TD, Hecker A, Steppacher SD, Novais EN, Kiapour AM. The doctor will also observe the patients gait (manner of walking) to look for signs of out-toeing or gait compensation. A random sample of CT images (46 hips) was selected, and femoral version was independently measured twice by two residents with 6 years (FS) and 2 years (JRK) of experience to assess intraobserver reproducibility and interobserver reliability. to call, please leave a message and we will return your call. An official website of the United States government. The epidemiology of bilateral slipped capital femoral epiphysis. FEMORAL VEIN ANATOMY. 26. During this time period, 754 patients were diagnosed with SCFE.
