Murphy SB, Simon SR, Kijewski PK, Wilkinson RH, Griscom NT. (2) These formulae facilitate preparation of computer programs and tables for the routine clinical determination of the anteversion and cervico-diaphyseal angles. External Tibial Torsion Much like internal tibial torsion, this condition improves in most children before or around the age of 10. 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. In healthy contralateral hips, we found differences for 9 of 10 pairwise comparisons (Table 4). 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). Bone Joint J. In some cases, a minimally invasive version of a femoral osteotomy may be performed. Femoral version by measurement method and by side (affected versus contralateral) was summarized using the mean, SD, and 95% confidence interval. The prevalence of femoral retroversion was higher in hips with SCFE for the proximal methods of Lee et al. [19] method -19 16 [95% CI -25 to -12] versus -19 16 [95% CI -23 to -15]; p = 0.90, respectively) (Table 5). Mechanical factors in slipped capital femoral epiphysis. Clinical data is missing for assessment of clinical and radiological outcome, as well as complications. 2021 May 1;479(5):960-961. doi: 10.1097/CORR.0000000000001704. The orientation of the distal femoral condyles served as the distal reference axis for all five measurement methods. Femorln retroverze.

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. These differences increased when including the femoral heads center as a reference. 1999;81:1747-1770. [35]; range, -53 to 15) to 100 (Murphy et al. Elise struggled with femoral retroversion, also known as hip retroversion which is a condition related to hip dysplasia. This work was performed at the Department of Orthopaedic Surgery, Boston Childrens Hospital, Harvard Medical School, Boston, MA, USA. Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. 2014;96:1441-1448. 2018 Apr;476(4):890-899. doi: 10.1007/s11999.0000000000000127. Chadayammuri V, Garabekyan T, Bedi A, et al. SELECTED PROCEEDINGS FROM THE 2020 BERNESE HIP SYMPOSIUM GUEST EDITOR: KLAUS-ARNO SIEBENROCK MD. 5, 9, 11 It is diagnosed when the feet of a prewalking child are . [30]: -4 16) (Fig. Tightness of the muscles of the hip that cause the hip to rotate excessively to the outside. 2) and hip ROM [ 32, 33 ]. 28. Conclusion Femoral antetorsion can be measured rapidly and with good reproducibility with MR imaging. Clin Orthop Relat Res. 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). J Bone Joint Surg Am. Top-view illustrations of excessive femoral retroversion. Retrotorsion is a pathologic decrease in the torsion angle; ie it is less than 8 degrees. 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.). The mean age at the time of CT was 15 4 years. The remaining four measurement methods use the femoral heads center as the most proximal reference. 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. Questions/purposes: Montgomery AA, Graham A, Evans PH, Fahey T. Inter-rater agreement in the scoring of abstracts submitted to a primary care research conference. 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 retroversion is often a congenital condition, meaning children are born with it. Seventy-two percent of the patients in our cohort were overweight or obese. The mean overall femoral version angles increased for hips with SCFE using more-distal landmarks compared with more-proximal landmarks. 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. Among 10 possible pairwise combinations, we detected differences for 8 pairwise comparisons in hips with SCFE (Table 4). 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. This website uses cookies. Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. This condition can affect patients of all ages and leads to abnormal stress in the low back, hip and knee and abnormal gait. 5. For more information, please refer to our Privacy Policy. Schmaranzer F, Todorski IAS, Lerch TD, Schwab J, Cullmann-Bastian J, Tannast M. Intra-articular lesions: imaging and surgical correlation. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. 1956;88:3-41. Femoral anteversion is a medical condition in which the neck of femur bone leans forward as compared to the rest of the femur. If a thickened medial plica is suspected, this can be palpated over the medial femoral condyle with the knee at 30. This procedure may be done for children over age 10 and adults and has a quick and reliable recovery. To facilitate communication among physicians and for the design of future studies, we recommend consistently reporting the applied measurement technique. The effect of femoral and acetabular version on clinical outcomes after arthroscopic femoroacetabular impingement surgery. Wolters Kluwer Health
This can cause pain and abnormal force in the hip and can lead to degeneration and arthritis. 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. Most proximally (Lee et al. 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). [30] is the preferred routine measurement because it most closely reflects the true anatomic femoral version [7, 30] and does not underestimate excessively high femoral version [37]. Stanitski CL, Woo R, Stanitski DF. 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. Fabricant PD, Fields KG, Taylor SA, Magennis E, Bedi A, Kelly BT. However, in excessive cases, surgery may be needed to correct the rotation. Craig's test is a passive test that is used to measure femoral anteversion or forward torsion of the femoral neck. Slipped capital femoral epiphysis: prevalence, pathogenesis, and natural history. Would you like email updates of new search results? I've recently turned 18 and I want to share my experience of femoral retroversion. The I-bars represent the corresponding 95% CI. 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. Retroversion refers to an abnormal backward rotation of the hip relative to the knee. 3D femoral neck anteversion measurements based on the posterior femoral plane in ORTHODOC system. Pain in the hip has been present for over 1 year, limiting activities. (47% [95% CI 36% to 58%] and 60% [95% CI 49% to 71%], respectively [all p < 0.001]). Left: Position of a retroverted femoral head with the foot facing straight forward. More specifically, the prevalence of femoral retroversion was higher in hips with SCFE for the proximal methods of Lee et al. 27. Thus, to assess the full extent of an SCFE deformity, femoral version measurements should consider the position of the displaced epiphysis. 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). My doctors would not treat me unless I had surgery to fix the retroversion. 14. Coxa valga and antetorta increases differences among different femoral version measurements : potential implications for derotational femoral osteotomy planning. 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. 2019;37:1571-1579. Analogously, we found excellent agreement (ICC > 0.80) for intraobserver reproducibility (reader 1, range 0.91 to 0.96) and interobserver reliability (range 0.89 to 0.98) for all five measurement methods in healthy contralateral hips. 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]. The prevalence of femoral retroversion (< 0) was compared using a chi-square test. 2016;98:21-27. However, the association between reduced femoral anteversion and SCFE has yet to be fully elucidated because early studies were small and based on two-dimensional CT scans. The hip joint is where the femoral head (the top of the femur) meets the pelvis. Double plating for proximal humeral fractures (PHF) is an option to increase the primary fixation stability. 2020;14:190-200. 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]. Oduwole KO, de SA D, Kay J, et al. Remodelling of femoral head-neck junction in slipped capital femoral epiphysis: a multicentre study. Schmaranzer F, Kallini JR, Miller PE, Kim Y-J, Bixby SD, Novais EN. This could theoretically affect anatomic landmark selection for femoral version measurements and corresponding femoral version angles. Based on these findings, we believe it is worthwhile to add evaluation of femoral version to the diagnostic workup of children with SCFE. 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.

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. official website and that any information you provide is encrypted 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). Clin Orthop Relat Res. 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. One radiology resident (6 years of experience) measured femoral version of the entire study group using five different methods.

By contrast, Stanitski et al. However, among the remaining measurement methods, it is not possible to recommend one measurement method over another based on our findings. Femoral Retroversion This condition rarely causes long-term problems, however, in some, it may predispose to slipped capital femoral epiphysis (SCFE). government site. Treatment of chronic, stable slipped capital femoral epiphysis via surgical hip dislocation with combined osteochondroplasty and Imhauser osteotomy. 2018;46:122-134. 2020;30:5281-5297. Furthermore, the sample sizes in these studies that compared femoral version between the affected and unaffected hip in patients with unilateral SCFE were small. This highlights the need for an individual analysis of femoral version and precludes any generalized recommendation about surgical correction of femoral version when a femoral osteotomy is planned. Kiapour AM, Kiapour A, Maranho DA, Kim Y-J, Novais EN. This study has several limitations. Three-dimensional CT was performed with all patients supine in the neutral position. femoral retroversion (___ degrees), femoral retroversion (physical finding), femoral retroversion, Femoral retroversion. The doctor will also observe the patients gait (manner of walking) to look for signs of out-toeing or gait compensation. Femoral retroversion is a positional deformity caused by contracture of the external rotator muscles of the hip. 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. Furthermore, the reliability and reproducibility of these measurements in patients with SCFE is unknown. Relative contribution of epiphyseal tubercle and peripheral cupping to capital femoral epiphysis stability during daily activities. 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. The minimum slice thickness was 2 mm. 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. 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. 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). Measurement on axial HASTE images (proximal and distal femur): Lerch TD, Boschung A, Todorski IAS, et al. 2006;44:895-906. , and. Cartilage is a semi-rigid but flexible avascular connective tissue found at various sites within the body. Loder RT, Aronson DD, Greenfield ML. Novais EN, Hosseinzadeh S, Emami SA, Maranho DA, Kim YJ, Kiapour AM. We found that femoral neck version is asymmetrically decreased by -8 in unilateral hips with SCFE compared with contralateral hips. [19] and Reikers et al. Congenital right femoral retroversion; Congenital right hip dysplasia; Present On Admission. 39. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. In the remaining four patients with an open femoral growth plate at last clinical visit, radiographic follow-up was longer than 18 months (median 22 months, range 21 to 25), an observation period by which more than 90% of the subsequent contralateral SCFE reportedly occur [25]. Many children born with femoral retroversion grow out it. 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. One radiology resident (6 years of experience) measured femoral version of the entire study group using five different methods. J Bone Joint Surg Am. Femoral retroversion can also occur after a physical trauma such as a femur fracture. 41. 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. In some cases, hip/femoral retroversion may be combined with a separate torsional deformity, such as a rotation in the tibia. Many children are born with femoral anteversions that they eventually grow out of. We detected mean differences ranging from -19 to 4 (all p < 0.005) for 8 of 10 pairwise comparisons in hips with SCFE. Level III, prognostic study. Bethesda, MD 20894, Web Policies 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. Said differently, the knee is excessively twisted inward relative to the hip. What is the prevalence of cam deformity after prophylactic pinning of the contralateral asymptomatic hip in unilateral slipped capital femoral epiphysis? (2) How do the mean femoral version angles and the prevalence of femoral retroversion change depending on the measurement method used? Therefore, we asked: (1) Do femoral version and the prevalence of femoral retroversion differ between hips with SCFE and the asymptomatic contralateral side? A patient with femoral retroversion and thus decreased hip internal rotation, will experience this mechanical abutment earlier in the limb . (1) Do femoral version and the prevalence of femoral retroversion differ between hips with SCFE and the asymptomatic contralateral side? Approach to the hip for SCFE: the North American perspective. Finally, we could show that the different measurement methods are comparable in terms of interobserver reliability and reproducibility (Table 6). and most-distal methods (Tomczak et al. Therefore, quantifying femoral version in patients with SCFE should be based on a measurement technique that includes the femoral rotations center. 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]. Retroversion refers to an abnormal backward rotation of the hip relative to the knee. 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. and Tomczak et al. 2019 May;477(5):1073-1083. doi: 10.1097/CORR.0000000000000610. Baraka MM, Hefny HM, Thakeb MF, et al. Of the 754 patients diagnosed with SCFE between 2000 and 2017, 172 patients had undergone pelvic CT scans. Novais EN, Millis MB. 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. 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. Wylie JD, Beckmann JT, Maak TG, Aoki SK. Bone Jt Open. 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. 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. Berryman F, Pynsent P, McBryde C. A semi-automated method for measuring femoral shape to derive version and its comparison with existing methods. 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 Eur Radiol. Depending on the measurement method, femoral version angles vary considerably in hips with high femoral anteversion [37]. What are the symptoms of femoral retroversion? 44. Conclusion: 8600 Rockville Pike [35]. Femoral anteversion causes the child's knees and feet to turn inward, or have what is also known as a "pigeon-toed" appearance. [44], and Murphy 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. Unable to load your collection due to an error, Unable to load your delegates due to an error. 2015;97:537-543. Am J Sports Med. And if left untreated into adolescence, these abnormal femoral rotations can also contribute to the degeneration or arthritis of the hip. The most significant clinical implication of femoral retroversion is that it is not soft tissue-related. [30]), and the corresponding prevalence of femoral retroversion were compared between hips with SCFE and the unaffected contralateral side. 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. Thus, the hip possesses three degrees of freedom of motion with three correspondingly arranged, mutually . Out-toeing is the common name used for a condition known as femoral retroversion. FEMORAL VEIN ANATOMY. In some cases, hip/femoral retroversion may be combined with a separate torsional deformity, such as a rotation in the tibia. 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. This is comparable to the femoral neck version of the contralateral hips in our study population. Please enable it to take advantage of the complete set of features! A study of children in Michigan. 3). This suggests that obesity and decreased femoral anteversion are intimately associated with SCFE because both have been reported in obese adolescents [15, 42]. 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. Femoral retroversion causes hip impingement, similar to the impingement and posterior instability that occurs in total hip arthroplasty. January 31, 2022 . Accordingly, the methods of Lee et al. 19 Finally, excessive femoral anteversion may This yielded a mean difference of -19 7 (95% CI -21 to -18; p < 0.001) between the methods of Lee et al. 1996;5:74-76. What are the causes of femoral retroversion? 2017;6:472-480. Also called hip anteversion, femoral anteversion refers to a forward (inward) rotation in the femur (thigh bone and knee) which connects to the pelvis to form the hip joint. 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. 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. 21. to call, please leave a message and we will return your call. 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). to maintaining your privacy and will not share your personal information without
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).
