[30]) when including the femoral heads center as a reference to account for displacement of the epiphysis (Fig. 2013;95:851-854. retroversion, reduced thoracic kyphosis (TK), increased knee flexion, and increased pelvic shift to balance the SVA, indicat-ing that other sagittal parameters influence sagittal align-ment.9,10 Additionally, cervical sagittal parameters relate to HRQoL and disability, stressing the importance of considering 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). The first symptom of femoral retroversion is usually a visual recognition of the rotated femur. Unlike in- toeing, out-toeing may lead to pain and disability as the child grows into adulthood. 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. Request PDF | On Apr 6, 2015, Henry Knipe and others published Femoral retroversion | Find, read and cite all the research you need on ResearchGate Most proximally (Lee et al. acetabulum - tends to be deformed in front, there may be eversion of the labrum, the bony + cartilaginous part of the acetabulum is broken, the dislocation is directed ventrally and proximally; neck of the femur - antetorsion associated with valgus, pressure change on the edge of the acetabulum J Bone Joint Surg Am. Journal of Clinical Medicine. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. Clin Orthop Relat Res. femoral retroversion synonyms, femoral retroversion pronunciation, femoral retroversion translation, English dictionary definition of femoral retroversion. 47. (3) What is the interobserver reliability and intraobserver reproducibility of these measurement methods? and Tomczak et al. A modified Imhuser osteotomy: an assessment of the addition of an open femoral neck osteoplasty. The mean femoral neck version was lower in hips with SCFE than in the contralateral side (-2 13 versus 7 11; p < 0.001). 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. Z Orthop Ihre Grenzgeb. 19. This is also called in-toeing. 2) and hip ROM [ 32, 33 ]. Therefore, we asked: (1) Do femoral version and the prevalence of femoral retroversion differ between hips with SCFE and the asymptomatic contralateral side? 2014;30:1314-1325. The site is secure. The human hip is a modified spherical (ball-and-socket) joint. Thus, to assess the full extent of an SCFE deformity, femoral version measurements should consider the position of the displaced epiphysis. and most-distal methods (Tomczak et al. The femur bone is cut through a portal and an intramedullary rod is inserted into the marrow cavity of the bone. Double plating for proximal humeral fractures (PHF) is an option to increase the primary fixation stability. 2020:296:381-390. Osteotomy to correct the alignment is rarely needed. Results: Clin Orthop Relat Res. [18] reported normal femoral neck version of 8.8 9.7 in 328 hips without radiographic signs of osteoarthritis. 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. 26. Slipped capital femoral epiphysis: prevalence, pathogenesis, and natural history. Intraclass correlations: uses in assessing rater reliability. From proximal to distal, this included the most-proximal methods (Lee et al. The hip joint is where the femoral head (the top of the femur) meets the pelvis. At times, pure femoral retroversion may be the only source of hip impingement. 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). A subset of patients was measured twice by two readers (FS, JRK) to assess intraobserver reproducibility and interobserver reliability. 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. Based on these findings, we believe it is worthwhile to add evaluation of femoral version to the diagnostic workup of children with SCFE. The prevalence of femoral retroversion was higher in hips with SCFE for the proximal methods of Lee et al. In this position, the femoral head is not positioned normally in the hip joint. 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. 2014;96:1119-1123. Clinical Orthopaedics and Related Research, Get new journal Tables of Contents sent right to your email inbox, The Association of Bone and Joint Surgeons, https://journals.lww.com/clinorthop/Fulltext/2019/05000/Differences_in_Femoral_Torsion_Among_Various.26.aspx. 37. 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. At birth the angle of torsion is 30-35 degrees and the femoral head faces anteriorly in the acetabulum. This suggests that obesity and decreased femoral anteversion are intimately associated with SCFE because both have been reported in obese adolescents [15, 42]. What is the prevalence of cam deformity after prophylactic pinning of the contralateral asymptomatic hip in unilateral slipped capital femoral epiphysis? Approach to the hip for SCFE: the North American perspective. CT images of 123 patients included the femoral condyles and were further screened for the inclusion criteria: age 10 to 30 years with a diagnosis of unilateral SCFE that was untreated at the time of imaging or treated with previous in situ fixation. From proximal to distal, this included the most-proximal methods (Lee et al. The state of being turned or tilted back. Femoral retroversion | definition of femoral retroversion by Medical dictionary femoral retroversion Also found in: Dictionary, Thesaurus, Encyclopedia. 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. 39. 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. River Terrace Wolters Kluwer Health The effect of modality and landmark selection on MRI and CT femoral torsion angles. Definition of the distal femoral reference: the medial and lateral posterior condyles are connected. These methods differ regarding the definition of the second reference point to determine the proximal reference line (Table 2). Pain in the hip has been present for over 1 year, limiting activities. Tnnis D, Heinecke A. Acetabular and femoral anteversion: relationship with osteoarthritis of the hip. Retrotorsion is a pathologic decrease in the torsion angle; ie it is less than 8 degrees. The prevalence of femoral retroversion was high in patients with SCFE and increased when using proximal anatomic landmarks. The right leg is 1.5 cm longer than normal. 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). 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. Bone Joint J. 3D femoral neck anteversion measurements based on the posterior femoral plane in ORTHODOC system. This surgery includes cutting and realigning the femur. [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]. J Child Orthop. [42] found higher mean femoral neck version of 9.3 in seven patients (five with obesity) with unilateral SCFE. 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. 17. At a mean follow-up of 58 46 months, the femoral growth plate was closed in 95% (75 of 79) of patients. Remodelling of femoral head-neck junction in slipped capital femoral epiphysis: a multicentre study. A specialist will observe your . Bethesda, MD 20894, Web Policies 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. 33. 2016;98:127-134. 2. This yielded a mean side-by side difference of -8 11 (95% CI -11 to -6; p < 0.001) and a higher prevalence of femoral retroversion in hips with SCFE (58% [95% CI 47% to 69%]; p < 0.001) than on the contralateral side (29% [95% CI 19% to 39%]). Several factors, including obesity and a decreased femoral anteversion angle, have been associated with the development of slipped capital femoral epiphysis (SCFE) [31]. The effects of simulated microgravity on the static and dynamic properties of large arteries are still mostly unknown. 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. 2014;96:1441-1448. government site. 2023; 12(3):751. https: . Diagnosing femoral retroversion can sometimes be difficult, as the common positioning for X-ray imaging may not reveal a rotation in the femoral neck. 2012;28:965-971. [35]. Femoral Anteversion Angle (Clinical Hip Anatomy) The Anatomist Elif Craig's Test The Student Physical Therapist 7 Exercises You Should Do Absolutely Every Day. A subset of patients was measured twice by the first observer and by a second orthopaedic resident (2 years of experience) to assess intraobserver reproducibility and interobserver reliability; for this assessment, we used intraclass correlation coefficients. 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. AR is associated with changes in load transmission across the hip, being a risk factor for early. J Bone Joint Surg Am. 35. The Lisbon agreement on femoroacetabular impingement imaging-part 1: overview. He may also order an. 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). (2) These formulae facilitate preparation of computer programs and tables for the routine clinical determination of the anteversion and cervico-diaphyseal angles. Acetabular retroversion has been proposed to contribute to the development of osteoarthritis of the hip. 12. In other words the knee is excessively twisted inward relative to the hip. 2019:47:3120-3132. Abduction of the forefoot associated with pes planovalgus. [30] (47% [95% CI 36% to 58%] and 60% [95% CI 49% to 71%], respectively [all p < 0.001]) (Table 3). In severe cases, however, surgery may be needed to correct the rotation. Questions/purposes: Furthermore, the sample sizes in these studies that compared femoral version between the affected and unaffected hip in patients with unilateral SCFE were small. Case reports: acetabular damage after mild slipped capital femoral epiphysis. The association of femoral retroversion with slipped capital femoral epiphysis. Furthermore, the prevalence of actual femoral retroversion and the effect of different measurement methods has yet to be studied in SCFE. 2018;38(suppl 1):S5-S12. This graph shows a comparison of the different methods to measure femoral version for hips with SCFE and contralateral hips. 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. 3). Clin Orthop Relat Res. Please try after some time. This graph shows a comparison of the different methods to measure femoral version, MeSH Coxa valga and antetorta increases differences among different femoral version measurements : potential implications for derotational femoral osteotomy planning. The method of Reikers et al. The prevalence of femoral retroversion (< 0) was compared using a chi-square test. 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). 1987;69:1169-1176. In some cases, a minimally invasive version of a femoral osteotomy may be performed. The hip joint is where the femoral head (the top of the femur) meets the pelvis. and Reikers et al.) femoroacetabular impingement. Symptoms of femoral retroversion usually begin with the visual recognition of the rotated femur. Retroversion of the femur may cause anterior femoroacetabular impingement. 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. The greatest differences were between measurement methods that are based on the most-proximal landmarks and those based on the more-distal landmarks. Thus, a normal rotation between the hip and the knee is established, correcting the torsional deformity. Differences in Femoral Torsion Among Various Measurement Methods Increase in Hips With Excessive Femoral Torsion. Fifty-one percent (40 of 79) of patients presented with severe SCFE based on the head-shaft angle described by Southwick [40] (< 30 mild, 30 to 60 moderate, and > 60 severe) measured on preoperative frog-leg lateral views. 2013 Jul;471(7):2163-72. doi: 10.1007/s11999-012-2715-7. J Orthop Trauma. 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. to -22 13 (95% CI -25 to -19; p < 0.001) according to the method of Murphy et al. The classic radiographic parameters to characterize femoroacetabular impingement secondary to SCFE include the slip angle and alpha angle measured on radiographs [28]. 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. This procedure may be done for children over age 10 and adults and has a quick and reliable recovery. Hip/Femoral Anteversion: Causes, Symptoms, Treatment There are 2 types of femoral version: Femoral Anteversion; Femoral Retroversion AR is associated with changes in load transmission across the hip, being a risk factor for early osteoarthrosis. 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. 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. Recognizing this impairment and its impact on a patient's function is . Southwick WO. The prevalence of femoral retroversion was high in patients with SCFE, and even higher when retroversion was defined and diagnosed using proximal anatomic landmarks. Bali NS, Harrison JO, Bache CE. [30]; range, -39 to 61) using different measurement methods (Table 3). The condition is usually congenital, meaning children are born with it. To facilitate communication among physicians and for the design of future studies, we recommend consistently reporting the applied measurement technique. J Child Orthop. Among 10 possible pairwise combinations, we detected differences for 8 pairwise comparisons in hips with SCFE (Table 4). 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). She was treated with an open reduction and bracing in infancy. Contact Dr. Jarman, DPM Phoenix Podiatrist. Femoral neck version was measured as the orientation of the femoral neck. Clipboard, Search History, and several other advanced features are temporarily unavailable. We found that femoral neck version is asymmetrically decreased in unilateral SCFE compared with the contralateral hip. Disclaimer, National Library of Medicine The condition is usually congenital, meaning children are born with it. 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. By continuing to use this website you are giving consent to cookies being used. Arthroscopy. Femoral retroversion causes hip impingement, similar to the impingement and posterior instability that occurs in total hip arthroplasty. An important mark of this deformity is the reduced or absent offset between the femoral head and the neck, which can be radiographically graded. Accordingly, differences in femoral version angles between proximal and distal measurement methods were as high as -19 (Table 4). A Type I error rate of 5% was used. 6. [44], and Murphy 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). Passive hip range of motion predicts femoral torsion and acetabular version. The hip joint is where the femoral head (the top of the femur) meets the pelvis. Femoral anteversion. 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. 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. We could show that assessing the femoral necks orientation alone underestimates the degree of external rotation subsequent to displacement of the epiphysis by 13 9 (Table 4). For the diagnosis of this condition, conventional AP pelvic radiographs may represent a reliable, easily available diagnostic modality as they can be obtained with a reproducible technique allowing the anterior and posterior acetabular rims to be visible for assessment. This study has several limitations. 45. Initial diagnosis of unilateral SCFE was based on an absence of radiographic signs of SCFE and of pain at clinical examination. Montgomery AA, Graham A, Evans PH, Fahey T. Inter-rater agreement in the scoring of abstracts submitted to a primary care research conference. All measurement methods are based on true axial images and a line connecting the femoral condyles as the distal reference axis. 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]. 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. However, Koerner et al. . The mean age was 59.5 12 years and the . Arthroscopy. This site needs JavaScript to work properly. 38. Mechanical risk factors for SCFE include rapid growth spurts, femoral retroversion, and femoral neck shaft angle. This yielded a mean side-by-side difference of -8 11 (95% CI -11 to -6; p < 0.001) and a higher prevalence of femoral retroversion on the SCFE side of 58% (95% CI 47% to 69%) than on the contralateral side (29% [95% CI 19% to 39%]; p < 0.001) (Table 3). The I-bars represent the corresponding 95% CI. 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. Common complications include secondary arthrosis and. to call, please leave a message and we will return your call. (91% [95% CI 85% to 97%] and 84% [95% CI 76% to 92%], respectively) than for the distal measurement methods of Tomczak et al. Paired t-tests including Bonferroni corrections for repeated measurements were performed for comparison between the mean femoral version angles. and most-distal methods (Tomczak et al. A subset of patients was measured twice by the first observer and by a second orthopaedic resident (2 years of experience) to assess intraobserver reproducibility and interobserver reliability; for this assessment, we used intraclass correlation coefficients. Mechanical factors in slipped capital femoral epiphysis. 29. We detected mean differences ranging from -19 to 4 (all p < 0.005) for 8 of 10 pairwise comparisons in hips with SCFE. 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]. Abstract Slipped capital femoral epiphysiolysis (SCFE) may result in femoroacetabular. 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. femoral retroversion. This could theoretically affect anatomic landmark selection for femoral version measurements and corresponding femoral version angles. [19] and Tomczak et al. The exact cause of femoral retroversion is unknown. However, in excessive cases, surgery may be needed to correct the rotation. (2) How do the mean femoral version angles and the prevalence of femoral retroversion change depending on the measurement method used? 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). 2017;11:93-98. 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). 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.

Schmaranzer, Department of Diagnostic, Interventional and Pediatric Radiology, Inselspital, Bern University Hospital, University of Bern, Freiburgstrasse, 3010 Bern, Switzerland, Email: [emailprotected]. Femoral anteversion describes the inward rotation of the femur bone in the upper leg. Femoral anteversion occurs in up to 10 percent of children. and Reikers et al. NCI CPTC Antibody Characterization Program. 2019;477:1073-1083. SCFE and its complications may lead to lifelong disability encompassing pain, gait disturbances, degenerative changes, osteonecrosis and chondrolysis. Lerch TD, Todorski IAS, Steppacher SD, et al. 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. [44]: 0 13 and Murphy et al. Previous studies only included the femoral neck version and not the center of the femoral head as a reference [15, 42]. This is the story of her diagnosis, operations and recovery to date: Hi I'm Elise and I live in Northern Ireland. It has been reported that some degree of remodeling of the femoral head-neck junction can be expected after fixation of the epiphysis over time [1, 9]. Among these, the greatest differences were between the most-proximal methods and the more-distal methods. 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). Video case study [30]), and the corresponding prevalence of femoral retroversion were compared between hips with SCFE and the unaffected contralateral side. This means thehip is twisted backward (posteriorly) in relation to the knee. What is femoral anteversion? Out-toeing is the common name used for a condition known as femoral retroversion. This is comparable to the femoral neck version of the contralateral hips in our study population. BMC Health Serv Res. 3). The I-bars represent the corresponding 95% CI. 2002;2:8. 1993;75:1141-1147. Isolated open or arthroscopic cam resection has been increasingly proposed as less-invasive options in patients with mild-to-moderate slips, yielding promising short-term results [6, 32, 46].
