Many children are born with femoral anteversions that they eventually grow out of. After applying prespecified inclusion and exclusion criteria, we included 79 patients. Acetabular retroversion has been proposed to contribute to the development of osteoarthritis of the hip. Wolters Kluwer Health 2019;37:1571-1579. The hip joint is where the femoral head (the top of the femur) meets the pelvis. [44] and Murphy et al. . Purpose. 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. Psychol Bull. 2017;11:93-98. PMC Passive hip range of motion predicts femoral torsion and acetabular version. Background: 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. 28. J Bone Joint Surg Am. What are the causes of femoral retroversion? The human hip is a modified spherical (ball-and-socket) joint. The data table on the chart reports the mean SD. Proximal femoral physis shear in slipped capital femoral epiphysis--a finite element study. (1) Do femoral version and the prevalence of femoral retroversion differ between hips with SCFE and the asymptomatic contralateral side? 2006;44:895-906. Causes of the Anteversion and Retroversion of the Hip The mean femoral neck version was lower in hips with SCFE than in the contralateral side (-2 13 versus 7 11; p < 0.001). Theoretically, hip flexion/abduction could affect femoral version measurements. The condition is usually congenital, meaning children are born with it. Femoral retroversion can result in the crushing of the labrum. Czech. 15. Femoral version of the general population: does normal vary by gender or ethnicity? The effects of simulated microgravity on the static and dynamic properties of large arteries are still mostly unknown. Femoral Retroversion. Liu RW, Fraley SM, Morris WZ, Cooperman DR. Validity and clinical consequences of a rotational mechanism for slipped capital femoral epiphysis. Out-toeing may be caused by: Femoral retroversion. See also: retroversion J Orthop Trauma. External Tibial Torsion Much like internal tibial torsion, this condition improves in most children before or around the age of 10. 2. Femoral neck version, the femoral version angles based on the measurement methods that include the femoral heads center (the methods of Lee et al. and Reikers et al.) 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. Akiyama M, Nakashima Y, Kitano T, et al. Some error has occurred while processing your request. 2014;96:1441-1448. 2023; 12(3):751. https: . The site is secure. The condition is somewhat more common in girls than boys. 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. He may also order an. Three-dimensional CT was performed with all patients supine in the neutral position. Case reports: acetabular damage after mild slipped capital femoral epiphysis. Imhauser G. Pathogenesis and therapy of hip dislocation in youth [in German]. Slipped capital femoral epiphysis: prevalence, pathogenesis, and natural history. "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? 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. J Bone Joint Surg Am. Compression fixation after biplane intertrochanteric osteotomy for slipped capital femoral epiphysis. Med Biol Eng Comput. Femoral anteversion is diagnosed through observation and examination. Femoral version by measurement method and by side (affected versus contralateral) was summarized using the mean, SD, and 95% confidence interval. In the axial HASTE images over the proximal and distal femur a femoral retroversion can be seen, i.e. Mascarenhas VV, Castro MO, Rego PA, et al. Mechanical risk factors for SCFE include rapid growth spurts, femoral retroversion, and femoral neck shaft angle. Following exclusion of a total of 36% (44 patients), the final cohort consisted of 79 patients (Table 1). Coxa vara. This work was performed at the Department of Orthopaedic Surgery, Boston Childrens Hospital, Harvard Medical School, Boston, MA, USA. [30] (47% [95% CI 36% to 58%] and 60% [95% CI 49% to 71%], respectively [all p < 0.001]) (Table 3). Please try again soon. 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. and Murphy et al.). 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. Because the epiphysis is displaced posteroinferiorly in patients with SCFE, such measurements may underestimate the severity of the deformity. January 31, 2022 . She was treated with an open reduction and bracing in infancy. Surgical treatment of femoroacetabular impingement following slipped capital femoral epiphysis: a systematic review. Femoral version is a relevant measurement that affects hip range of motion and pathology. Many children born with femoral retroversion grow out of it. Sucato DJ. to -22 13 (95% CI -25 to -19; p < 0.001) according to the method of Murphy et al. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. 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). [19] and Reikers et al. 3). 5, 9, 11 It is diagnosed when the feet of a prewalking child are . Accessibility J Bone Joint Surg Am. The Lisbon agreement on femoroacetabular impingement imaging-part 1: overview. [44] (Table 4). 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. All CT scans including axial images covering the osseous pelvis and distal femoral condyles were used to measure femoral version. References 1 article features images from this case At the time of CT, the femoral growth plate of the asymptomatic contralateral side was already closed in 42% (33 of 79) of patients. 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. J Child Orthop. 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. Retroversion of the femur may cause anterior femoroacetabular impingement. 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 2015;97:537-543. Conclusion: This website uses cookies. This procedure may be done for children over age 10 and adults and has a quick and reliable recovery. This surgery includes cutting and realigning the femur. Definition of the distal femoral reference: the medial and lateral posterior condyles are connected. At birth the angle of torsion is 30-35 degrees and the femoral head faces anteriorly in the acetabulum. 2013;95:851-854. 1973;55:1218-1224. 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. Contact Dr. Jarman, DPM Phoenix Podiatrist. 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. 2020:296:381-390. (2) How do the mean femoral version angles and the prevalence of femoral retroversion change depending on the measurement method used? may email you for journal alerts and information, but is committed Thus, this should not jeopardize the results of our study to a relevant degree. The association of femoral retroversion with slipped capital femoral epiphysis. SCFE and its complications may lead to lifelong disability encompassing pain, gait disturbances, degenerative changes, osteonecrosis and chondrolysis. [30] uses the center superior to the lesser trochanter at the base of the femoral neck as a landmark. Femoral retroversion is common in newborns because of contracture of the hip from intrauterine positioning. [30]; range, -39 to 61) using different measurement methods (Table 3). 24. Schmaranzer F, Lerch TD, Siebenrock KA, Tannast M, Steppacher SD. 46. 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. Top-view illustrations of excessive femoral retroversion. Femoral retroversion is also often called hip retroversion. Novais EN, Hosseinzadeh S, Emami SA, Maranho DA, Kim YJ, Kiapour AM. Most proximally (Lee et al. 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. 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. Femoral retroversion is often a congenital condition, meaning children are born with it. 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. The mean age was 59.5 12 years and the . [42] found higher mean femoral neck version of 9.3 in seven patients (five with obesity) with unilateral SCFE. In these situations, a surgical procedure known as a femoral osteotomy may be used. 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. Kim, E. N. Novais, Department of Orthopaedic Surgery, Boston Childrens Hospital, Harvard Medical School, Boston, MA, USA, F. Schmaranzer, Department of Diagnostic, Interventional and Pediatric Radiology, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland, J. D. Wylie, The Orthopedic Specialty Hospital, Intermountain Healthcare, Murray, UT, USA, F. Schmaranzer, Department of Diagnostic, Interventional and Pediatric Radiology, Inselspital, Bern University Hospital, University of Bern, Freiburgstrasse, 3010 Bern, Switzerland, Email: [emailprotected]. Femoral anteversion is a medical condition in which the neck of femur bone leans forward as compared to the rest of the femur. J Bone Joint Surg Am. To facilitate communication among physicians and for the design of future studies, we recommend consistently reporting the applied measurement technique. Clin Orthop Relat Res. Thus, to assess the full extent of an SCFE deformity, femoral version measurements should consider the position of the displaced epiphysis. Since the range of femoral version angles was wide, femoral version cannot be predicted in a given hip and must be assessed individually. and Murphy et al.). Data is temporarily unavailable. 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. FOIA All five methods were compared side-by-side (involved versus uninvolved hip), and comparisons among all five methods were performed using paired t-tests. It becomes apparent as the child starts to stand or cruise between 6 and 9 months. Kiapour AM, Kiapour A, Maranho DA, Kim Y-J, Novais EN. , and. 23. 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. A preoperative 3D-CT-scan was performed for 3D simulation of hip impingement ( Fig. 2020;30:5281-5297. Interrater reliability was assessed across raters using an ICC (2,2) model and intrarater reliability was assessed using an ICC (3,1) model [39]. One radiology resident (6 years of experience) measured femoral version of the entire study group using five different methods. HHS Vulnerability Disclosure, Help 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. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. 1956;88:3-41. 519 East 72nd St., Suite 204 Bali NS, Harrison JO, Bache CE. Tomczak RJ, Guenther KP, Rieber A, Mergo P, Ros PR, Brambs HJ. Intraclass correlations: uses in assessing rater reliability. 2012 Dec;470(12):3432-8. doi: 10.1007/s11999-012-2452-y. Wylie JD, Beckmann JT, Maak TG, Aoki SK. Please enable scripts and reload this page. 18. 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. Level III, prognostic study. 2018 Apr;476(4):890-899. doi: 10.1007/s11999.0000000000000127. 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). FEMORAL VEIN ANATOMY. Femoral anteversion describes the inward rotation of the femur bone in the upper leg. The prevalence of femoral retroversion (< 0) was compared using a chi-square test. [30] (Table 3). Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. Galbraith RT, Gelberman RH, Hajek PC, et al. We showed that femoral neck version is asymmetrically decreased in unilateral SCFE, and that differences increase when including the femoral heads center. 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. Coxa valga and antetorta increases differences among different femoral version measurements : potential implications for derotational femoral osteotomy planning. 5. is femoral anteversion a disability. 1. Pritchett JW, Perdue KD. This yielded a mean difference of -19 7 (95% CI -21 to -18; p < 0.001) between the methods of Lee et al. Bone Joint J. The five different measurement methods were applied in the same way in hips with SCFE and in healthy contralateral hips (Fig. 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. Furthermore, the prevalence of actual femoral retroversion and the effect of different measurement methods has yet to be studied in SCFE. 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. Time from SCFE diagnosis to CT was 1.8 2.5 years (Table 1). Clinical outcomes after arthroscopic psoas lengthening: the effect of femoral version. 2021 May 1;479(5):960-961. doi: 10.1097/CORR.0000000000001704. The data table on the chart reports the mean SD. 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. Southwick WO. 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. The role of cartilage in joints is to protect bone, smooth the friction between bones, and prevent At times, pure femoral retroversion may be the only source of hip impingement.
