2019;43:2375-2382. 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. 1987;5:523-528. AJR Am J Roentgenol. 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. 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. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. 17. This procedure may be done for children over age 10 and adults and has a quick and reliable recovery. to call, please leave a message and we will return your call. Oduwole KO, de SA D, Kay J, et al. Hip dysplasia. Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. Femoral version of the general population: does normal vary by gender or ethnicity? Define femoral retroversion. Retrotorsion is a pathologic decrease in the torsion angle; ie it is less than 8 degrees. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. Top-view illustrations of excessive femoral retroversion. 2011;31:153-158. Copyright 2020 by the Association of Bone and Joint Surgeons. The impingement is accentuated if there is concomitant acetabular retroversion, a cam or pincer lesion, coxa profunda, or protrusio. Slipped capital femoral epiphysis: prevalence, pathogenesis, and natural history. [19] and Reikers et al. BMC Health Serv Res. J Orthop Trauma. method), we used the most cephalic junction of the greater trochanter as the landmark and, most distally, we used the center base of the femoral neck superior to the lesser trochanter (Murphy et al.). More recently, femoral osteochondroplasty sometimes has been performed first to correct a secondary cam deformity, followed by intraoperative ROM testing to determine whether an additional proximal femoral osteotomy is needed [4, 34, 43]. One radiology resident (6 years of experience) measured femoral version of the entire study group using five different methods. The overall mean femoral version angles increased for hips with SCFE (range of means -19 to 0) and the contralateral side (range of means 2 to 19) using distal landmarks compared with more proximal landmarks (Fig. The articular cartilage is intact. 2002;2:8. Clipboard, Search History, and several other advanced features are temporarily unavailable. Femoral retroversion is a condition in which the femoral neck is rotated backward on the femoral shaft. 1988;8:385-388. The prevalence of femoral retroversion was high in patients with SCFE and increased when using proximal anatomic landmarks. [30] (47% [95% CI 36% to 58%] and 60% [95% CI 49% to 71%], respectively [all p < 0.001]) (Table 3). Stanitski CL, Woo R, Stanitski DF. This can cause pain and abnormal force in the hip and can lead to degeneration and arthritis. Novais EN, Millis MB. River Terrace
Millis MB. 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. Mascarenhas VV, Castro MO, Rego PA, et al. Prevalence of femoral and acetabular version abnormalities in patients with symptomatic hip disease: a controlled study of 538 hips. Seventy-one percent (56 of 79) of patients in whom previous in situ pinning had been performed as the initial treatment of SCFE presented with a symptomatic SCFE deformity. 479(5):960-961, May 2021. The data table on the chart reports the mean SD. Berryman F, Pynsent P, McBryde C. A semi-automated method for measuring femoral shape to derive version and its comparison with existing methods.

Baraka MM, Hefny HM, Thakeb MF, et al. Kiapour AM, Kiapour A, Maranho DA, Kim Y-J, Novais EN. We detected mean differences ranging from -19 to 4 (all p < 0.005) for 8 of 10 pairwise comparisons in hips with SCFE. to maintaining your privacy and will not share your personal information without
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). The https:// ensures that you are connecting to the We showed that femoral neck version is asymmetrically decreased in unilateral SCFE, and that differences increase when including the femoral heads center. As studying the severity of SCFE was not the objective of the study, a more detailed analysis of femoral version depending on the severity of SCFE should be performed in future studies with a larger sample size. 212-606-1415| 212-606-1550| 212-606-1637 | 212-606-1097. A modified Imhuser osteotomy: an assessment of the addition of an open femoral neck osteoplasty. Therefore, quantifying femoral version in patients with SCFE should be based on a measurement technique that includes the femoral rotations center. 2009;467:724-731. The remaining four measurement methods use the femoral heads center as the most proximal reference. may email you for journal alerts and information, but is committed
Disclaimer, National Library of Medicine 47. This graph shows a comparison of the different methods to measure femoral version, MeSH (3) What is the interobserver reliability and intraobserver reproducibility of these measurement methods? For the definition of femoral neck version, the midpoint of the femoral neck axis is determined at the level where the cortices run parallel and serves as the proximal reference axis (Fig. Common complications include secondary arthrosis and. . 2006;44:895-906. Recognizing this impairment and its impact on a patient's function is . Reduced femoral neck version is more common in adolescents with obesity than in those without obesity [14]. 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. 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. and Murphy et al. is femoral anteversion a disability. Based on these findings, we believe it is worthwhile to add evaluation of femoral version to the diagnostic workup of children with SCFE. 3D femoral neck anteversion measurements based on the posterior femoral plane in ORTHODOC system. This condition is diagnosed in childhood, and is characterized by the unusual "duck feet" posture and walk that the child develops. (2) How do the mean femoral version angles and the prevalence of femoral retroversion change depending on the measurement method used? Medial joint line: medial meniscus, medial femoral condyle, and tibial and femoral insertions of the medial collateral ligament (MCL). . During the early childhood some degree of internal rotation is always present. We reviewed our institutional database for patients who were treated for SCFE and had undergone pelvic CT scanning for surgical planning. A turning or tilting backward. (3) What is the interobserver reliability and intraobserver reproducibility of these measurement methods? 2017;21:487-506. Email is the best way to reach out for an appointment. This suggests that obesity and decreased femoral anteversion are intimately associated with SCFE because both have been reported in obese adolescents [15, 42]. official website and that any information you provide is encrypted The prevalence of femoral retroversion was high in patients with SCFE and increased when using proximal anatomic landmarks. 1999;81:1747-1770. The mean femoral neck version was lower in hips with SCFE than in the contralateral side (-2 13 versus 7 11; p < 0.001). Clin Orthop Relat Res. Video case study 42. 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. It also appears to be related to the position of the baby as it grows in the womb. The prevalence of femoral retroversion (< 0) was compared using a chi-square test. In some cases, hip/femoral retroversion may be combined with a separate torsional deformity, such as a rotation in the tibia. [19]) compared with distal landmarks to define the femoral reference axis (47% for the method of Tomczak et al. Fabricant PD, Bedi A, De La Torre K, Kelly BT. Approach to the hip for SCFE: the North American perspective. The classic radiographic parameters to characterize femoroacetabular impingement secondary to SCFE include the slip angle and alpha angle measured on radiographs [28]. Retroversion refers to an abnormal backward rotation of the hip relative to the knee. J Bone Joint Surg Am. 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 . 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 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). 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. Femoral malversion (excessive femoral anteversion or femoral retroversion) is increasingly recognised as an important factor that may influence mechanical loads around the hip and development of both intra-articular and extra-articular pathologies. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. To the best of our knowledge, there are no normal reference values for CT-based femoral neck version measurements in children. The mean age was 15 4 years, 48% (38 of 79) of the patients were male, and 56% (44 of 79) were obese (defined as a BMI > 95th percentile (mean BMI 34 9 kg/m2). government site. Level III, prognostic study. For this retrospective, controlled, single-center study, we reviewed our institutional database for patients who were treated for unilateral SCFE and who had undergone a pelvic CT scan. J Child Orthop. For those who do not, a mild case may not cause significant health problems. 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. Differences in femoral torsion among various measurement methods increase in hips with excessive femoral torsion. The I-bars represent the corresponding 95% CI. The method of Murphy et al. Femoral anteversion occurs in up to 10 percent of children. To promote the development of an optimally functional total hip prosthesis for medium and large dog breeds, accurate measurements of the normal anatomy of the proximal femur and acetabular retroversion are essential. Congenital right femoral retroversion; Congenital right hip dysplasia; Present On Admission. External tibial torsion. Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. Abnormalities in hip joint morphology, such as developmental dysplasia of the hip (DDH) and femoroacetabular impingement, have been shown to alter hip mechanics and promote the development of end-stage hip OA. SCFE: clinical aspects, diagnosis, and classification. The hip joint is where the femoral head (the top of the femur) meets the pelvis. n. 1. 1983;54:18-23. Symptoms, Causes, Treatment for Out-Toeing, the common name used for a condition known as femoral retroversion. We performed a retrospective, controlled, single-center study at a tertiary pediatric care center and included patients with SCFE treated between 2000 and 2017. 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]. From proximal to distal, this included the most-proximal methods (Lee et al. Cartilage is a semi-rigid but flexible avascular connective tissue found at various sites within the body. 8600 Rockville Pike Femoral anteversion is a medical condition in which the neck of femur bone leans forward as compared to the rest of the femur. Slipped capital femoral epiphysis: prevalence, pathogenesis, and natural history. 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. Imhauser G. Pathogenesis and therapy of hip dislocation in youth [in German]. However, Koerner et al. 6 It is the angular 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. Relative contribution of epiphyseal tubercle and peripheral cupping to capital femoral epiphysis stability during daily activities. Depending on the measurement method, femoral version angles vary considerably in hips with high femoral anteversion [37]. Definition of the distal femoral reference: the medial and lateral posterior condyles are connected. [19] and Reikers et al. Novais EN, Hosseinzadeh S, Emami SA, Maranho DA, Kim YJ, Kiapour AM. "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? [44]) (Table 3). [30] uses the center superior to the lesser trochanter at the base of the femoral neck as a landmark. Although our findings support the association among obesity, femoral retroversion, and SCFE, it remains unclear how an increase in body weight can lead to asymmetric reduction in femoral neck version. 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. Since the range of femoral version angles was wide, femoral version cannot be predicted in a given hip and must be assessed individually. Femoral anteversion. 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. Results: From proximal to distal, this included the most-proximal methods (Lee et al. The definition of the proximal reference axis differs among the five methods. 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. A subset of patients was measured twice by two readers (FS, JRK) to assess intraobserver reproducibility and interobserver reliability. 2013;27:308-311. 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. Furthermore, the sample sizes in these studies that compared femoral version between the affected and unaffected hip in patients with unilateral SCFE were small. femoral anteversion. The role of cartilage in joints is to protect bone, smooth the friction between bones, and prevent Erickson JB, Samora WP, Klingele KE. Thus, we compared femoral version angles and the prevalence of femoral retroversion in hips with SCFE with the unaffected contralateral side and among different measurement techniques. Retroversion of the femur may cause anterior femoroacetabular impingement. Based on these findings, we believe it is worthwhile to add evaluation of femoral version to the diagnostic workup of children with SCFE. External Tibial Torsion Much like internal tibial torsion, this condition improves in most children before or around the age of 10. Is femoral Retroversion a disability? 2020;14:98-105. 30. It is typically detected when the child is 4 years to 6 years old. 2012 Dec;470(12):3432-8. doi: 10.1007/s11999-012-2452-y. [19] method -19 16 [95% CI -25 to -12] versus -19 16 [95% CI -23 to -15]; p = 0.90, respectively) (Table 5). It is also known as 'Trochanteric Prominence Angle Test (TPAT)'. The exact cause of femoral retroversion is unknown. 14. Among these, the greatest differences were between the most-proximal methods and the more-distal methods. In these situations, a surgical procedure known as a femoral osteotomy may be used. This graph shows a comparison of the different methods to measure femoral version for hips with SCFE and contralateral hips. Clin Orthop Relat Res. 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]. Femoral retroversion could result from developmental conditions such as focal femoral deficiency, and dysplasia or be acquired secondary to malunited subtrochanteric, intertrochanteric or femoral neck fracture, varus derotational osteotomies and slipped capital femoral epiphysis (SCFE). In patients with implant failure following in situ fixation, this included assessment of the femoral growth plate for planning of revision in situ fixation. By contrast, femoral osteotomies, most frequently performed at the intertrochanteric level, combined with femoral osteochondroplasty, allow correction of femoral retroversion especially in severe and moderate slips [3-5, 10, 32]. The data table on the chart reports the mean SD. The vessel traverses the thigh and takes a superficial course at the femoral triangle before passing beneath the inguinal ligament into the pelvis as the external iliac vein (figure 1A-B). 39. Case reports: acetabular damage after mild slipped capital femoral epiphysis. Bone Joint Res. J Bone Joint Surg Am. J Orthop Res. Abduction of the forefoot associated with pes planovalgus. femoral retroversion synonyms, femoral retroversion pronunciation, femoral retroversion translation, English dictionary definition of femoral retroversion. Out-toeing may be caused by: Femoral retroversion. The state of being turned or tilted back. 2) and hip ROM [ 32, 33 ]. American Heritage Dictionary of the English Language, Fifth Edition.. Femoral retroversion can also occur after a physical trauma such as a femur fracture. Am J Sports Med. Questions/purposes: [19] and Tomczak et al. 2017;11:284-288. Children with femoral anteversion may trip and fall more than their peers, but the condition is rarely painful. Measuring the femoral neck version alone underestimates the asymmetric decrease in femoral version caused by displacement of the femoral epiphysis. Elise struggled with femoral retroversion, also known as hip retroversion which is a condition related to hip dysplasia. While both femoral anteversion and retroversion do not always cause discomfort, they can eventually bring about pain in the lower back, hip, and knee. 1997;168:791-794. 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. sharing sensitive information, make sure youre on a federal 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. and Reikers et al. 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. CORR Insights: How Common Is Femoral Retroversion and How Is it Affected by Different Measurement Methods in Unilateral Slipped Capital Femoral Epiphysis? We retrospectively examined 35 patients with unilateral PHF, who were treated with double plating for PHF between 2013 and 2019. [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]. Basheer SZ, Cooper AP, Maheshwari R, Balakumar B, Madan S. Arthroscopic treatment of femoroacetabular impingement following slipped capital femoral epiphysis. [30]; range, -39 to 61) using different measurement methods (Table 3). 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. 43. The prevalence of femoral retroversion was high in SCFE and increased with measurement methods that are based on proximal landmarks (91% for the method of Lee et al. You may be trying to access this site from a secured browser on the server. Chadayammuri V, Garabekyan T, Bedi A, et al. However, an excessive femoral retroversion can place stress on hip and knee joints, often leading to joint pain and abnormal wear. 38. 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. Ethical approval for this study was obtained from the institutional review board of Boston Childrens Hospital (protocol number IRB-P00018761). 1). Time from SCFE diagnosis to CT was 1.8 2.5 years (Table 1). We found that femoral neck version is asymmetrically decreased by -8 in unilateral hips with SCFE compared with contralateral hips. References 1 article features images from this case The hip joint and psoas muscle lie directly deep to the femoral . Femoral retroversion is common in early infancy and is caused by external rotation contracture of the hip secondary to intrauterine packing. Bookshelf A patient with femoral retroversion and thus decreased hip internal rotation, will experience this mechanical abutment earlier in the limb . 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. J Pediatr Orthop. We showed that femoral neck version is asymmetrically decreased in unilateral SCFE, and that differences increase when including the femoral head's center. 2. A preoperative 3D-CT-scan was performed for 3D simulation of hip impingement ( Fig. and Murphy et al.). 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. 8. [19], Reikers et al. SCFE and its complications may lead to lifelong disability encompassing pain, gait disturbances, degenerative changes, osteonecrosis and chondrolysis. The orientation of the distal femoral condyles served as the distal reference axis for all five measurement methods. Lerch TD, Todorski IAS, Steppacher SD, et al. 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. femoroacetabular impingement. In the axial HASTE images over the proximal and distal femur a femoral retroversion can be seen, i.e. [1] Femoral anteversion is the angle between the femoral neck and femoral shaft, indicating the degree of torsion of the femur. Many children born with femoral retroversion grow out of it. If a thickened medial plica is suspected, this can be palpated over the medial femoral condyle with the knee at 30. 20. Femoral anteversion causes the child's knees and feet to turn inward, or have what is also known as a "pigeon-toed" appearance. The prevalence of femoral retroversion (< 0) was compared using a chi-square test. Said differently, the knee is excessively twisted inward relative to the hip. 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). Surgical dislocation in the management of pediatric and adolescent hip deformity. Conclusion Femoral antetorsion can be measured rapidly and with good reproducibility with MR imaging. 22. In hips with SCFE, there was a mean difference of -13 9 (95% CI -15 to -12; p < 0.001) between femoral neck version and Reikers et al.s [35] method, which reflects femoral neck orientation relative to the femoral heads center (Table 4). The effect of modality and landmark selection on MRI and CT femoral torsion angles. At the time of CT, the femoral growth plate of the asymptomatic contralateral side was already closed in 42% (33 of 79) of patients. How Common Is Femoral Retroversion and How Is it Affected by Different Measurement Methods in Unilateral Slipped Capital Femoral Epiphysis? 2020:296:381-390.

Causes of the Anteversion and Retroversion of the Hip Methods: femoral retroversion (___ degrees), femoral retroversion (physical finding), femoral retroversion, Femoral retroversion. Thus, to assess the full extent of an SCFE deformity, femoral version measurements should consider the position of the displaced epiphysis. Double plating for proximal humeral fractures (PHF) is an option to increase the primary fixation stability. Retroversin femoral. 12. This is comparable to the femoral neck version of the contralateral hips in our study population. Gelberman et al. Osteotomy to correct the alignment is rarely needed. Third, because of the studys retrospective design, we cannot rule out a selection bias since the decision to perform a CT was not standardized and evolved over time in the practices of the different surgeons. Based on these findings, we believe it is worthwhile to add evaluation of femoral version to the diagnostic workup of children with SCFE. J Bone Joint Surg Am. 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. Among the remaining methods, the prevalence of femoral retroversion was higher for hips with SCFE (all p < 0.001), which ranged from 47% (Tomczak et al.s [44] method) to 91% (Lee et al.s [19] method) compared with 4% (Murphy et al.s [30] method) to 42% (Lee et al.s [19] method) for the contralateral side (Table 3).
