Schmaranzer, Florian MD, PhD; Kallini, Jennifer R. MD; Ferrer, Mariana G. MD; Miller, Patricia E. MSc; Wylie, James D. MD; Kim, Young-Jo MD, PhD; Novais, Eduardo N. MD, F. Schmaranzer, J. R. Kallini, M. G. Ferrer, P. E. Miller, J. D. Wylie, Y-J. 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. femoral anteversion. 42. The mean femoral neck version was lower in hips with SCFE than in the contralateral side (-2 13 versus 7 11; p < 0.001). Symptoms of Out-Toeing - Femoral Retroversion It is easily recognizable because the child develops an unusual walk. Femoral Retroversion. J Bone Joint Surg Am. Although external rotation of the proximal femur relative to the femoral condyles (that is, femoral retroversion) has been linked with the onset of SCFE and has been proposed to result from a rotation of the femoral epiphysis around the epiphyseal tubercle leading to femoral retroversion, femoral version has rarely been described in SCFE [24, 31]. Previous studies only included the femoral neck version and not the center of the femoral head as a reference [15, 42]. [30] uses the center superior to the lesser trochanter at the base of the femoral neck as a landmark. Disclaimer, National Library of Medicine The most significant clinical implication of femoral retroversion is that it is not soft tissue-related. Define femoral retroversion. Tightness of the muscles of the hip that cause the hip to rotate excessively to the outside. Arthroscopic treatment of mild to moderate deformity after slipped capital femoral epiphysis: intra-operative findings and functional outcomes. Right: Most patients with excessive hip retroversion compensate by walking out-toed. 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. 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 . [19] and Reikers et al. 22. "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? 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. English. Before Lerch TD, Boschung A, Todorski IAS, et al. J Orthop Res. 13. Abduction of the forefoot associated with pes planovalgus. Thus, to assess the full extent of an SCFE deformity, femoral version measurements should consider the position of the displaced epiphysis. J Child Orthop. In some cases, hip/femoral retroversion may be combined with a separate torsional deformity, such as a rotation in the tibia. What is femoral anteversion? The remaining four measurement methods use the femoral heads center as the most proximal reference. femoral retroversion. Osteotomy through the lesser trochanter for slipped capital femoral epiphysis. To facilitate communication among physicians and for the design of future studies, we recommend consistently reporting the applied measurement technique. 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). J Orthop Trauma. SCFE: clinical aspects, diagnosis, and classification. 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. 2015;31:247-253. The condition is usually congenital, meaning children are born with it. J Bone Joint Surg Am. 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. official website and that any information you provide is encrypted The role of cartilage in joints is to protect bone, smooth the friction between bones, and prevent Schmaranzer F, Kallini JR, Miller PE, Kim Y-J, Bixby SD, Novais EN. In this position, the femoral head is not positioned normally in the hip joint. 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]. American Heritage Dictionary of the English Language, Fifth Edition.. 2019 May;477(5):1073-1083. doi: 10.1097/CORR.0000000000000610. 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). The prevalence of femoral retroversion was high in our study and ranged from 47% to 91%, depending on the applied measurement method (Table 3). 2016;98:21-27. 30. 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. To the best of our knowledge, there are no normal reference values for CT-based femoral neck version measurements in children. A modified Imhuser osteotomy: an assessment of the addition of an open femoral neck osteoplasty. grip" deformity) and relative retroversion of the femoral head were dened as the cause of cam-type FAI, with worse long-term clinical and radiographic results. In these situations, a surgical procedure known as a femoral osteotomy may be used. and Tomczak et al. 31. Clin Orthop Relat Res. We performed a retrospective, controlled, single-center study at a tertiary pediatric care center and included patients with SCFE treated between 2000 and 2017. In many cases, the abnormal rotation of the femur develops while the fetus is growing in the womb. To facilitate communication among physicians and for the design of future studies, we recommend consistently reporting the applied measurement technique. The femur bone is cut through a portal and an intramedullary rod is inserted into the marrow cavity of the bone. 29. 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. Femoral version of the general population: does normal vary by gender or ethnicity? 47. (91% [95% CI 85% to 97%] and 84% [95% CI 76% to 92%], respectively) than for the distal measurement methods of Tomczak et al. Retroversion refers to an abnormal backward rotation of the hip relative to the knee. The condition is somewhat more common in girls than boys. In the axial HASTE images over the proximal and distal femur a femoral retroversion can be seen, i.e. 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]. 2017;6:472-480. Bali K, Railton P, Kiefer GN, Powell JN. 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. The method of Reikers et al. Novais EN, Hosseinzadeh S, Emami SA, Maranho DA, Kim YJ, Kiapour AM. Contact Dr. Jarman, DPM Phoenix Podiatrist. Femoral Retroversion This condition rarely causes long-term problems, however, in some, it may predispose to slipped capital femoral epiphysis (SCFE). External Tibial Torsion Much like internal tibial torsion, this condition improves in most children before or around the age of 10. Wylie JD, McClincy MP, Uppal N, et al. Abstract Slipped capital femoral epiphysiolysis (SCFE) may result in femoroacetabular. Acetabular retroversion (AR) consists of a malorientation of the acetabulum in the sagittal plane. Therefore, quantifying femoral version in patients with SCFE should be based on a measurement technique that includes the femoral rotations center. Mechanical factors in slipped capital femoral epiphysis. The exact cause of femoral retroversion is unknown. 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). The retroversion was causing a minor curvature in my lumbar spine, tendinosis in my hamstring, and labral tears. These differences increased when including the femoral heads center as a reference. The state of being turned or tilted back. 2018 Apr;476(4):890-899. doi: 10.1007/s11999.0000000000000127. 1988;8:385-388. Schmaranzer F, Todorski IAS, Lerch TD, Schwab J, Cullmann-Bastian J, Tannast M. Intra-articular lesions: imaging and surgical correlation. Methods: 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. 26. Depending on the measurement method, femoral version angles vary considerably in hips with high femoral anteversion [37]. More recently, femoral osteochondroplasty sometimes has been performed first to correct a secondary cam deformity, followed by intraoperative ROM testing to determine whether an additional proximal femoral osteotomy is needed [4, 34, 43]. Clin Orthop Relat Res. Based on these findings, we believe it is worthwhile to add evaluation of femoral version to the diagnostic workup of children with SCFE. 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). [] reported an association of SCFE and femoral retroversion.More recently, many studies have shown an association . Loder RT, Aronson DD, Greenfield ML. 18. 7. Request PDF | On Apr 6, 2015, Henry Knipe and others published Femoral retroversion | Find, read and cite all the research you need on ResearchGate 5 Femoral version, also referred to as femoral torsion, is another morphologic variable being investigated. 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. (1) Do femoral version and the prevalence of femoral retroversion differ between hips with SCFE and the asymptomatic contralateral side? [30]) when including the femoral heads center as a reference to account for displacement of the epiphysis (Fig. 2016;36:239-246. (91% [95% CI 85% to 97%] and 84% [95% CI 76% to 92%], respectively) than for the distal measurement methods of Tomczak et al. Journal of Clinical Medicine. However, an excessive femoral retroversion can place stress on hip and knee joints, often leading to joint pain and abnormal wear. What are the causes of femoral retroversion? Combined Imhauser osteotomy and osteochondroplasty in slipped capital femoral epiphysis through surgical hip dislocation approach. femoral anteversion decreases on average 25 degrees during this time as well Presentation Symptoms anterior knee pain caused by patellofemoral malalignment Physical Exam thigh-foot axis measurement best way to evaluate tibial torsion average during infancy is 5 degrees internal rotation, that slowly derotates Femoral anteversion occurs in up to 10 percent of children. 2020:296:381-390. Femoral retroversion can also occur after a physical trauma such as a femur fracture. femoral retroversion synonyms, femoral retroversion pronunciation, femoral retroversion translation, English dictionary definition of femoral retroversion. All measurement methods are based on true axial images and a line connecting the femoral condyles as the distal reference axis. 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]. Int Orthop. If a thickened medial plica is suspected, this can be palpated over the medial femoral condyle with the knee at 30. The mean overall femoral version angles increased for hips with SCFE using more-distal landmarks compared with more-proximal landmarks. 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). 2013;37:2331-2336. J Bone Joint Surg Am. 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. Several factors, including obesity and a decreased femoral anteversion angle, have been associated with the development of slipped capital femoral epiphysis (SCFE) [31]. Fabricant PD, Bedi A, De La Torre K, Kelly BT. 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. Reikers O, Bjerkreim I, Kolbenstvedt A. Anteversion of the acetabulum and femoral neck in normals and in patients with osteoarthritis of the hip. 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%. Femoral neck version, the femoral version angles based on the measurement methods that include the femoral heads center (the methods of Lee et al. 1993;75:1141-1147. 3). The method of Murphy et al. 40. [19]) compared with distal landmarks to define the femoral reference axis (47% for the method of Tomczak et al. Please try again soon. 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 and Murphy et al. This study has several limitations. It is also known as 'Trochanteric Prominence Angle Test (TPAT)'. She was treated with an open reduction and bracing in infancy.
