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 showed that femoral neck version is asymmetrically decreased in unilateral SCFE, and that differences increase when including the femoral head's center. 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. and Tomczak et al. What is femoral anteversion? Obesity and decreased femoral anteversion in adolescence. This means thehip is twisted backward (posteriorly) in relation to the knee. The mean age was 59.5 12 years and the . 15. 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). [44] (Table 4). He may also order an. 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 anteversion. coronary heart disease, and other diseases due to long-term disability, bringing economic and spiritual double blows to patients and families. femoroacetabular impingement. A subset of patients was measured twice by two readers (FS, JRK) to assess intraobserver reproducibility and interobserver reliability. Femoral Retroversion.

Email is the best way to reach out for an appointment. This website uses cookies. 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. 46. The state of being turned or tilted back. 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. Limb Lengthening and Complex Reconstruction Service, out-toeing or "duck walk" walking with the foot pointed outward instead of straight ahead. Femoral version by measurement method and by side (affected versus contralateral) was summarized using the mean, SD, and 95% confidence interval. 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. References 1 article features images from this case 3). This surgery includes cutting and realigning the femur. The impingement is accentuated if there is concomitant acetabular retroversion, a cam or pincer lesion, coxa profunda, or protrusio. Clin Orthop Relat Res. 11. For those who do not grow out of it, a mild femoral retroversion may not cause any significant issues. 1997;168:791-794. If you prefer The prevalence of femoral retroversion (< 0) was compared using a chi-square test. 18. Journal of Clinical Medicine. Int J Numer Method Biomed Eng. Femoral neck version was measured as the orientation of the femoral neck. Bone Joint J. Among these, the greatest differences were between the most-proximal methods and the more-distal methods. All CT scans including axial images covering the osseous pelvis and distal femoral condyles were used to measure femoral version. 2021 May 1;479(5):960-961. doi: 10.1097/CORR.0000000000001704. 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]. 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. Thus, a normal rotation between the hip and the knee is established, correcting the torsional deformity. Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. AR is associated with changes in load transmission across the hip, being a risk factor for early. Limb Lengthening and Complex Reconstruction Service [19] and Reikers et al. (3) What is the interobserver reliability and intraobserver reproducibility of these measurement methods? 22. This study has several limitations. [44]) (Table 3). and Murphy et al. (2) How do the mean femoral version angles and the prevalence of femoral retroversion change depending on the measurement method used? 3D femoral neck anteversion measurements based on the posterior femoral plane in ORTHODOC system. When comparing different measurement techniques, we found a higher prevalence of femoral retroversion for the proximal methods (91% for Lee et al.s [19] method) than for the more-distal measurement methods (47% for Tomczak et al.s [44] method) (Table 3). 3. The definition of the proximal reference axis differs among the five methods. Time from SCFE diagnosis to CT was 1.8 2.5 years (Table 1). SCFE and its complications may lead to lifelong disability encompassing pain, gait disturbances, degenerative changes, osteonecrosis and chondrolysis. Lerch TD, Novais EN, Schmaranzer F, et al. In these situations, a surgical procedure known as a femoral osteotomy may be used. 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]. and Murphy et al. 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. The right leg is 1.5 cm longer than normal. The association of femoral retroversion with slipped capital femoral epiphysis. Compression fixation after biplane intertrochanteric osteotomy for slipped capital femoral epiphysis. In cases where the child does not grow out of femoral retroversion, the condition may be mild enough not to cause any significant health challenges. All measurement methods are based on true axial images and a line connecting the femoral condyles as the distal reference axis.

Retroversin femoral. An official website of the United States government. 10. The hip joint is where the femoral head (the top of the femur) meets the pelvis. In some cases, hip/femoral retroversion may be combined with a separate torsional deformity, such as a rotation in the tibia. 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. 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). Level of evidence: Lerch TD, Todorski IAS, Steppacher SD, et al. Gelberman RH, Cohen MS, Shaw BA, Kasser JR, Griffin PP, Wilkinson RH. Clin Orthop Relat Res. 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. and Reikers et al.) Mascarenhas VV, Castro MO, Rego PA, et al. 2018 Apr;476(4):890-899. doi: 10.1007/s11999.0000000000000127. 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. 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. Request PDF | On Apr 6, 2015, Henry Knipe and others published Femoral retroversion | Find, read and cite all the research you need on ResearchGate 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]. 45. [30] (Table 3). Novais EN, Hosseinzadeh S, Emami SA, Maranho DA, Kim YJ, Kiapour AM. 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). Schmaranzer F, Meier MK, Lerch TD, Hecker A, Steppacher SD, Novais EN, Kiapour AM. Clin Orthop Relat Res. 6 It is the angular 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]. During the early childhood some degree of internal rotation is always present. These side-by-side differences increased up to -22 (according to the method of Murphy et al. This position keeps the femoral head within the socket which minimizes pain. 2017;11:93-98. The hip joint is where the femoral head (the top of the femur) meets the pelvis. 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. (2) How do the mean femoral version angles and the prevalence of femoral retroversion change depending on the measurement method used? 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. Despite this proposed association, little is known about femoral neck version in patients with SCFE. Tightness of the muscles of the hip that cause the hip to rotate excessively to the outside. Please enable it to take advantage of the complete set of features! 1973;55:1218-1224. However, among the remaining measurement methods, it is not possible to recommend one measurement method over another based on our findings. 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. Berryman F, Pynsent P, McBryde C. A semi-automated method for measuring femoral shape to derive version and its comparison with existing methods. What is the prevalence of cam deformity after prophylactic pinning of the contralateral asymptomatic hip in unilateral slipped capital femoral epiphysis? An excessive femoral retroversion can place stress on hip and knee joints, often leading to joint pain and abnormal wear. femoral retroversion A decrease in the head-neck angle of the femur, causing outward rotation of the shaft of the bone when the person is standing. Therefore, we asked: (1) Do femoral version and the prevalence of femoral retroversion differ between hips with SCFE and the asymptomatic contralateral side? Interobserver reliability and intraobserver reproducibility were high (ICC values > 0.80) for all five measurement methods (Table 6). and most-distal methods (Tomczak et al. Femoral retroversion is often a congenital condition, meaning children are born with it. During this time period, 754 patients were diagnosed with SCFE. Future studies should compare femoral version in SCFE hips to age-matched volunteers without a history of hip disease. 2011;31:153-158. Abduction of the forefoot associated with pes planovalgus. Define femoral retroversion. 36. 2019;477:1111-1122. The classic radiographic parameters to characterize femoroacetabular impingement secondary to SCFE include the slip angle and alpha angle measured on radiographs [28]. The human hip is a modified spherical (ball-and-socket) joint. 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). 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. (1) Do femoral version and the prevalence of femoral retroversion differ between hips with SCFE and the asymptomatic contralateral side? Galbraith RT, Gelberman RH, Hajek PC, et al. Acetabular retroversion (AR) consists of a malorientation of the acetabulum in the sagittal plane. , . Femoral Retroversion This condition rarely causes long-term problems, however, in some, it may predispose to slipped capital femoral epiphysis (SCFE). Femoral retroversion is common in early infancy and is caused by external rotation contracture of the hip secondary to intrauterine packing. is femoral anteversion a disability. and transmitted securely. 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. CORR Insights: How Common Is Femoral Retroversion and How Is it Affected by Different Measurement Methods in Unilateral Slipped Capital Femoral Epiphysis? Radiology. All five methods were compared side-by-side (involved versus uninvolved hip), and comparisons among all five methods were performed using paired t-tests. Previous studies only included the femoral neck version and not the center of the femoral head as a reference [15, 42]. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. Sucato DJ. 1987;69:1169-1176. [30] (47% [95% CI 36% to 58%] and 60% [95% CI 49% to 71%], respectively [all p < 0.001]) (Table 3). In this position, the femoral head is not positioned normally in the hip joint. Several factors, including obesity and a decreased femoral anteversion angle, have been associated with the development of slipped capital femoral epiphysis (SCFE) [31]. 37. Prevalence of femoral and acetabular version abnormalities in patients with symptomatic hip disease: a controlled study of 538 hips. 1979;86:420-428. 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. From proximal to distal, this included the most-proximal methods (Lee et al. Slipped capital femoral epiphysis: prevalence, pathogenesis, and natural history. Arthroscopic treatment of mild to moderate deformity after slipped capital femoral epiphysis: intra-operative findings and functional outcomes. [30] uses the center superior to the lesser trochanter at the base of the femoral neck as a landmark. In many cases, the abnormal rotation of the femur develops while the fetus is growing in the womb. Torsional deformity can also occur after a fracture, if a broken bone heals with incorrectly (called malunion). 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). 12. Some abnormalities may resolve spontaneously. [19], Reikers et al. Children with femoral anteversion may trip and fall more than their peers, but the condition is rarely painful. To facilitate communication among physicians and for the design of future studies, we recommend consistently reporting the applied measurement technique. . We performed a subgroup analysis, and with the numbers available, we observed any differences in femoral version angles between patients with and without previous in situ fixation (Table 5). 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. 1956;88:3-41. 43. 2017;6:472-480. A modified Imhuser osteotomy: an assessment of the addition of an open femoral neck osteoplasty. Femoral anteversion is a medical condition in which the neck of femur bone leans forward as compared to the rest of the femur. This condition can affect patients of all ages and leads to abnormal stress in the low back, hip and knee and abnormal gait. A technical improvement. 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. Please try again soon. 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. 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. 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). 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. Lerch TD, Boschung A, Todorski IAS, et al. Furthermore, the sample sizes in these studies that compared femoral version between the affected and unaffected hip in patients with unilateral SCFE were small. 2006;26:291-294. In healthy contralateral hips, we found differences for 9 of 10 pairwise comparisons (Table 4). The effect of femoral and acetabular version on clinical outcomes after arthroscopic femoroacetabular impingement surgery. 2019;43:2375-2382. 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. J Pediatr Orthop. For both the SCFE side and contralateral side, we found an increasing prevalence of femoral retroversion when the more-proximal landmarks were selected (Table 3). CLINICAL FEATURES Symptoms Will cause out-toeing and may lead to disability and decrease physical performance. Purpose. Based on these findings, we believe it is worthwhile to add evaluation of femoral version to the diagnostic workup of children with SCFE. Femoral anteversion occurs in up to 10 percent of children; 99 percent of cases resolve over time without the need for surgery. The doctor will also observe the patients gait (manner of walking) to look for signs of out-toeing or gait compensation. J Bone Joint Surg Am. 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. 26. Femorln retroverze. 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. 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. Acetabular retroversion has been proposed to contribute to the development of osteoarthritis of the hip. [35]. A 10-year minimum followup study. It also appears to be related to the position of the baby as it grows in the womb. 41. 2016;98:21-27. J Pediatr Orthop. At times, pure femoral retroversion may be the only source of hip impingement. In some cases, hip/femoral retroversion may be combined with a separate torsional deformity, such as a rotation in the tibia. J Child Orthop. Clin Orthop Relat Res. Arthroscopy. 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. In severe cases, however, surgery may be needed to correct the rotation. Int Orthop. The method of Reikers et al. Data is temporarily unavailable. Bali K, Railton P, Kiefer GN, Powell JN. Bone Joint J. 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). Femoral Retroversion. However, an excessive femoral retroversion can place stress on hip and knee joints, often leading to joint pain and abnormal wear. 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. Tnnis D, Heinecke A. Acetabular and femoral anteversion: relationship with osteoarthritis of the hip. The statistical analysis was performed by a biostatistician (PEM) using SAS version 9.4 (SAS Institute, Cary, NC, USA). A preoperative 3D-CT-scan was performed for 3D simulation of hip impingement ( Fig. The five different measurement methods were applied in the same way in hips with SCFE and in healthy contralateral hips (Fig. Clipboard, Search History, and several other advanced features are temporarily unavailable. [35]; range, -53 to 15) to 100 (Murphy et al. We detected mean differences ranging from -19 to 4 (all p < 0.005) for 8 of 10 pairwise comparisons in hips with SCFE. For more information, please refer to our Privacy Policy. 16. Pain in the hip has been present for over 1 year, limiting activities. It becomes apparent as the child starts to stand or cruise between 6 and 9 months. Differences in Femoral Torsion Among Various Measurement Methods Increase in Hips With Excessive Femoral Torsion. We found that femoral neck version is asymmetrically decreased in unilateral SCFE compared with the contralateral hip. What Is the Association Among Epiphyseal Rotation, Translation, and the Morphology of the Epiphysis and Metaphysis in Slipped Capital Femoral Epiphysis? 2017;21:487-506. 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. Clin Orthop Relat Res. The first symptom of femoral retroversion is usually a visual recognition of the rotated femur. Chadayammuri V, Garabekyan T, Bedi A, et al. Surgical dislocation in the management of pediatric and adolescent hip deformity. External Tibial Torsion Much like internal tibial torsion, this condition improves in most children before or around the age of 10. Femoral retroversion can result in the crushing of the labrum. 29. 2002;2:8. 2020:296:381-390. 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). (91% [95% CI 85% to 97%] and 84% [95% CI 76% to 92%], respectively) than for the distal measurement methods of Tomczak et al. Accordingly, differences in femoral version angles between proximal and distal measurement methods were as high as -19 (Table 4). 5, 9, 11 It is diagnosed when the feet of a prewalking child are . 47. . Three-dimensional CT was performed with all patients supine in the neutral position. Is femoral Retroversion a disability? To facilitate communication among physicians and for the design of future studies, we recommend consistently reporting the applied measurement technique.

HHS Vulnerability Disclosure, Help 2016;98:127-134. The prevalence of femoral retroversion (< 0) was compared using a chi-square test. 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. This condition is diagnosed in childhood, and is characterized by the unusual "duck feet" posture and walk that the child develops. Right: Most patients with excessive hip retroversion compensate by walking out-toed. 40. 9. Based on these findings, we believe it is worthwhile to add evaluation of femoral version to the diagnostic workup of children with SCFE. 5 Femoral version, also referred to as femoral torsion, is another morphologic variable being investigated. 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. Osteotomy to correct the alignment is rarely needed. To the best of our knowledge, there are no normal reference values for CT-based femoral neck version measurements in children. However, an excessive femoral retroversion can place stress on hip and knee joints, often leading to joint pain and abnormal wear. Femoral anteversion is diagnosed through observation and examination. 2013;37:2331-2336. 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. Video case study A comprehensive analysis of femoral version may provide valuable baseline information to optimize surgical planning in hips with sequalae of SCFE and to allow standardization of studies investigating surgical correction of SCFE deformities. Depending on the measurement method, femoral version angles vary considerably in hips with high femoral anteversion [37]. From birth to 6 yrs. 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.).
