The hip joint is where the femoral head (the top of the femur) meets the pelvis. SELECTED PROCEEDINGS FROM THE 2020 BERNESE HIP SYMPOSIUM GUEST EDITOR: KLAUS-ARNO SIEBENROCK MD. 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). Femoral anteversion occurs in up to 10 percent of children; 99 percent of cases resolve over time without the need for surgery. However, in excessive cases, surgery may be needed to correct the rotation. Bob & Brad 3.9M views 5 years ago. 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]. Femoral antetorsion was significantly higher in patients with pincer-type FAI than in those with cam-type FAI for reader 1 (18.3 9.8 vs 10.0 9.1, P = .02) and reader 2 (18.7 10.5 vs 11.6 8.8, P = .04). Fishkin Z, Armstrong DG, Shah H, Patra A, Mihalko WM. Clin Orthop Relat Res. 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). 2023; 12(3):751. https: . Furthermore, the prevalence of actual femoral retroversion and the effect of different measurement methods has yet to be studied in SCFE. He may also order an. Femoral Anteversion Angle (Clinical Hip Anatomy) The Anatomist Elif Craig's Test The Student Physical Therapist 7 Exercises You Should Do Absolutely Every Day. 26. [30]), and the corresponding prevalence of femoral retroversion were compared between hips with SCFE and the unaffected contralateral side. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. We found that femoral neck version is asymmetrically decreased by -8 in unilateral hips with SCFE compared with contralateral hips. and Reikers et al.) 212-606-1415, About Limb Lengthening & Deformity Correction, Bone Tumors: Symptoms, Treatments and Outcomes, Femoral Anteversion: Causes, Symptoms and Treatment, Femoral Retroversion: Causes, Symptoms and Treatments. The prevalence of femoral retroversion (< 0) was compared using a chi-square test. 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 . My doctors would not treat me unless I had surgery to fix the retroversion. 29. This condition can affect patients of all ages and leads to abnormal stress in the low back, hip and knee and abnormal gait. Madhuri V, Arora SK, Dutt V. Slipped capital femoral epiphysis associated with vitamin D deficiency: a series of 15 cases. Femoral impingement in maximal hip flexion is anterior-inferior distal to the cam deformity in femoroacetabular impingement patients with femoral retroversion : implications for hip arthroscopy However, an excessive femoral retroversion can place stress on hip and knee joints, often leading to joint pain and abnormal wear. Causes of the Anteversion and Retroversion of the Hip 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. The data table on the chart reports the mean SD. Femoral retroversion is common in newborns because of contracture of the hip from intrauterine positioning. A study of children in Michigan. official website and that any information you provide is encrypted Case reports: acetabular damage after mild slipped capital femoral epiphysis. 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. 15 - 17 Furthermore, it can cause a decrease in the length of the abductor lever arm, 18 posterior extra-articular impingement, 9 and ischiofemoral impingement. The aim of the current study was to obtain precise normal values of the femoral anteversion angle using computed tomography on cadavers of mature dogs with normal hip joints of . After applying prespecified inclusion and exclusion criteria, we included 79 patients. Since the range of femoral version angles was wide, femoral version cannot be predicted in a given hip and must be assessed individually. 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. Elise struggled with femoral retroversion, also known as hip retroversion which is a condition related to hip dysplasia. 35. She was treated with an open reduction and bracing in infancy. This procedure may be done for children over age 10 and adults and has a quick and reliable recovery. Femoral retroversion is often a congenital condition, meaning it is present from birth and develops in the womb. Clinical Orthopaedics and Related Research479(5):947-959, May 2021. In this type of surgery, the femur bone is cut through a portal and an intramedullary rod is inserted into the marrow cavity of the bone. All five methods were compared side-by-side (involved versus uninvolved hip), and comparisons among all five methods were performed using paired t-tests. (2) How do the mean femoral version angles and the prevalence of femoral retroversion change depending on the measurement method used? The method of Reikers et al. 1993;75:1141-1147. J Child Orthop. The effect of modality and landmark selection on MRI and CT femoral torsion angles. Clinical data is missing for assessment of clinical and radiological outcome, as well as complications. 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). Lee YS, Oh SH, Seon JK, Song EK, Yoon TR. Femoral Retroversion This condition rarely causes long-term problems, however, in some, it may predispose to slipped capital femoral epiphysis (SCFE). However, severe cases require surgical correction. The institution of one or more of the authors (FS) has received, during the study period, funding from the Swiss National Science Foundation, Switzerland, Grant No. 2014;96:1441-1448. (1) Do femoral version and the prevalence of femoral retroversion differ between hips with SCFE and the asymptomatic contralateral side? We reviewed our institutional database for patients who were treated for SCFE and had undergone pelvic CT scanning for surgical planning. 1956;88:3-41. 36. 5 Femoral version, also referred to as femoral torsion, is another morphologic variable being investigated. A turning or tilting backward. Femoral retroversion often runs in families, which may indicate that some children have a higher risk of being born with this condition. In our cohort, femoral neck version was asymmetrically decreased (-2 13 versus 7 11) and the prevalence of femoral retroversion was higher (58% versus 29%) in hips with SCFE than in the healthy contralateral side (Table 3). 2013;95:e341-348. Fourth, although we compared our observations in SCFE hips with the unaffected contralateral side, we note that these hips may not reflect a normal population. The impingement is accentuated if there is concomitant acetabular retroversion, a cam or pincer lesion, coxa profunda, or protrusio. Level of evidence: Twenty-nine percent (23 of 79) of patients had no previous surgical treatment for SCFE. Combined Imhauser osteotomy and osteochondroplasty in slipped capital femoral epiphysis through surgical hip dislocation approach. Medial joint line: medial meniscus, medial femoral condyle, and tibial and femoral insertions of the medial collateral ligament (MCL). Femoral retroversion | definition of femoral retroversion by Medical dictionary femoral retroversion Also found in: Dictionary, Thesaurus, Encyclopedia. Disclaimer, National Library of Medicine [30]: -4 16) (Fig. The orientation of the distal femoral condyles served as the distal reference axis for all five measurement methods. 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]. Femoral version of the general population: does normal vary by gender or ethnicity? 2006;26:291-294. [44]) (Table 3). 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). Top-view illustrations of excessive femoral retroversion. Erickson JB, Samora WP, Klingele KE. Finite-element studies have demonstrated that shear forces across the capital femoral physis increase with reduced femoral anteversion and increased BMI [13, 33]. Arthroscopy. What is the prevalence of cam deformity after prophylactic pinning of the contralateral asymptomatic hip in unilateral slipped capital femoral epiphysis? In some cases, a minimally invasive version of a femoral osteotomy may be performed. (47% [95% CI 36% to 58%] and 60% [95% CI 49% to 71%], respectively [all p < 0.001]). 2021 May 1;479(5):935-944. doi: 10.1097/CORR.0000000000001590. (2) How do the mean femoral version angles and the prevalence of femoral retroversion change depending on the measurement method used? The mean age at the time of CT was 15 4 years. Further measurement methods included the femoral heads center and differed regarding the level of landmarks for the proximal femoral reference axis. This can cause pain and abnormal force in the hip and can lead to degeneration and arthritis. 34. 28. The effect of femoral and acetabular version on clinical outcomes after arthroscopic femoroacetabular impingement surgery. J Orthop Res. Wylie JD, McClincy MP, Uppal N, et al. This causes rotation of the legs inwards leading to twisting of the knee and foot towards the midline of the body (center of the body). 9. 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. Conclusion Femoral antetorsion can be measured rapidly and with good reproducibility with MR imaging. 1979;86:420-428. 4. 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. Clin Orthop Relat Res. Abduction of the forefoot associated with pes planovalgus. Copyright 2020 by the Association of Bone and Joint Surgeons. 18. and most-distal methods (Tomczak et al. SCFE and its complications may lead to lifelong disability encompassing pain, gait disturbances, degenerative changes, osteonecrosis and chondrolysis. 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. Proximal femoral physis shear in slipped capital femoral epiphysis--a finite element study. Symptoms, Causes, Treatment for Out-Toeing, the common name used for a condition known as femoral retroversion. 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. Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. The I-bars represent the corresponding 95% CI. The site is secure. Morphologic Features of the Contralateral Femur in Patients With Unilateral Slipped Capital Femoral Epiphysis Resembles Mild Slip Deformity: A Matched Cohort Study. 1, 7, 9 It becomes apparent when the prewalking. Montgomery AA, Graham A, Evans PH, Fahey T. Inter-rater agreement in the scoring of abstracts submitted to a primary care research conference. In patients with implant failure following in situ fixation, this included assessment of the femoral growth plate for planning of revision in situ fixation. 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. [19] and Reikers et al. 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). Femoral retroversion often runs in families, which may indicate that some children have a higher risk of being born with this condition. To facilitate communication among physicians and for the design of future studies, we recommend consistently reporting the applied measurement technique. Retroversion of the femur may cause anterior femoroacetabular impingement. 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. The condition is usually congenital, meaning children are born with it. 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. The remaining four measurement methods use the femoral heads center as the most proximal reference. Please try after some time. Right: Most patients with excessive hip retroversion compensate by walking out-toed. Femoral neck version, the femoral version angles based on the measurement methods that include the femoral heads center (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. Many children are born with femoral anteversions that they eventually grow out of. Reduced femoral neck version is more common in adolescents with obesity than in those without obesity [14].
