An important mark of this deformity is the reduced or absent offset between the femoral head and the neck, which can be radiographically graded. This graph shows a comparison of the different methods to measure femoral version for hips with SCFE and contralateral hips. We detected mean differences ranging from -19 to 4 (all p < 0.005) for 8 of 10 pairwise comparisons in hips with SCFE. Thus, to assess the full extent of an SCFE deformity, femoral version measurements should consider the position of the displaced epiphysis. 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. The mean age at the time of CT was 15 4 years. Femoral anteversion is a medical condition in which the neck of femur bone leans forward as compared to the rest of the femur. 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]. 35. Elise struggled with femoral retroversion, also known as hip retroversion which is a condition related to hip dysplasia. Recognizing this impairment and its impact on a patient's function is . We reviewed our institutional database for patients who were treated for SCFE and had undergone pelvic CT scanning for surgical planning. Femoral retroversion causes hip impingement, similar to the impingement and posterior instability that occurs in total hip arthroplasty. 2013;95:e341-348. Schmaranzer F, Lerch TD, Siebenrock KA, Tannast M, Steppacher SD. 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 . Previous studies only included the femoral neck version and not the center of the femoral head as a reference [15, 42]. Any treatment of my symptoms was going to be ineffective due to the alignment still being off. femoral retroversion (___ degrees), femoral retroversion (physical finding), femoral retroversion, Femoral retroversion. Diagnosing femoral retroversion can sometimes be difficult, as the common positioning for X-ray imaging may not reveal a rotation in the femoral neck. 19. Clin Orthop Relat Res. A turning or tilting backward. 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). Based on these findings, we believe it is worthwhile to add evaluation of femoral version to the diagnostic workup of children with SCFE. It is a structural adaptation that alters the shape of the thigh bonea point past sports medicine staff and physical therapists have failed to apply in Andrew's case. FOIA and Reikers et al. 2016;98:127-134. The site is secure. We found that femoral neck version is asymmetrically decreased by -8 in unilateral hips with SCFE compared with contralateral hips. External Tibial Torsion Much like internal tibial torsion, this condition improves in most children before or around the age of 10. 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. It is typically detected when the child is 4 years to 6 years old. The femur bone is cut through a portal and an intramedullary rod is inserted into the marrow cavity of the bone. 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. [44] (Table 4). Various methods to measure femoral version have been described that differ regarding the selection of anatomic landmarks to define the proximal reference axis [19, 30, 35, 36, 44]. 2017;21:487-506. Is femoral Retroversion a disability? . My doctors would not treat me unless I had surgery to fix the retroversion. Despite this proposed association, little is known about femoral neck version in patients with SCFE. 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). 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. 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). Accordingly, there was a mean difference of -16 6 (95% CI -17 to -15; p < 0.001) between the methods of Lee et al. 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. (2) How do the mean femoral version angles and the prevalence of femoral retroversion change depending on the measurement method used? Retroversion of the femur may cause anterior femoroacetabular impingement. Thus, to assess the full extent of an SCFE deformity, femoral version measurements should consider the position of the displaced epiphysis. femoroacetabular impingement. 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. In our institution, the method described by Murphy et al. In other words the knee is excessively twisted inward relative to the hip. 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]. Fabricant PD, Fields KG, Taylor SA, Magennis E, Bedi A, Kelly BT. Level III, prognostic study. 3). (3) What is the interobserver reliability and intraobserver reproducibility of these measurement methods? Depending on the measurement method, femoral version angles vary considerably in hips with high femoral anteversion [37]. 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. Subcapital osteotomy of the femoral neck for patients with healed slipped capital femoral epiphysis. [30]; range, -39 to 61) using different measurement methods (Table 3). Femoral neck version was measured as the orientation of the femoral neck. More specifically, the prevalence of femoral retroversion was higher in hips with SCFE for the proximal methods of Lee et al. Femoral retroversion can occur in one or both legs. The association of femoral retroversion with slipped capital femoral epiphysis. Femoral retroversion is often a congenital condition, meaning children are born with it. What is femoral anteversion? [35], Tomczak et al. It also appears to be related to the position of the baby as it grows in the womb. 2013;95:851-854. Femoral version in acute slipped capital femoral epiphysis. 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). Federal government websites often end in .gov or .mil. The greatest differences were between measurement methods that are based on the most-proximal landmarks and those based on the more-distal landmarks. Results: The prevalence of femoral retroversion (< 0) was compared using a chi-square test. It also appears to be related to the position of the baby as it grows in the womb. 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). Compression fixation after biplane intertrochanteric osteotomy for slipped capital femoral epiphysis. 20. official website and that any information you provide is encrypted Pain in the hip has been present for over 1 year, limiting activities. Lerch TD, Novais EN, Schmaranzer F, et al. Congenital right femoral retroversion; Congenital right hip dysplasia; Present On Admission. 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. coronary heart disease, and other diseases due to long-term disability, bringing economic and spiritual double blows to patients and families. . 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. To rule out any subsequent SCFE of the contralateral hip, we further assessed the status of the femoral growth plate at the time of CT and at latest follow-up. In some cases, the doctor may perform a less invasive version of a femoral osteotomy. Bone Jt Open. This position keeps the femoral head within the socket which minimizes pain. 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). 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. 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. Seventy-two percent of the patients in our cohort were overweight or obese. In hips with SCFE, there was a mean difference of -13 9 (95% CI -15 to -12; p < 0.001) between femoral neck version and Reikers et al.s [35] method, which reflects femoral neck orientation relative to the femoral heads center (Table 4). [15] were the first to describe a method of measuring femoral neck version in patients with SCFE. Furthermore, the sample sizes in these studies that compared femoral version between the affected and unaffected hip in patients with unilateral SCFE were small. 519 East 72nd St., Suite 204 [42] found higher mean femoral neck version of 9.3 in seven patients (five with obesity) with unilateral SCFE. Define femoral retroversion. CLINICAL FEATURES Symptoms Will cause out-toeing and may lead to disability and decrease physical performance. 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%]). Pritchett JW, Perdue KD. 2006;26:291-294. From proximal to distal, this included the most-proximal methods (Lee et al. Slipped capital femoral epiphysis: prevalence, pathogenesis, and natural history. Kiapour AM, Kiapour A, Maranho DA, Kim Y-J, Novais EN. References 1 article features images from this case This yielded a mean difference of -19 7 (95% CI -21 to -18; p < 0.001) between the methods of Lee et al. 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. Wylie JD, Beckmann JT, Maak TG, Aoki SK. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. This procedure may be done for children over age 10 and adults and has a quick and reliable recovery. This condition can affect patients of all ages and leads to abnormal stress in the low back, hip and knee and abnormal gait. 1996;5:74-76. Bookshelf the axis of the femoral neck is oriented more posteriorly than the distal reference line connecting the dorsal border of the femoral condyles. 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 . The most significant clinical implication of femoral retroversion is that it is not soft tissue-related. Japanese. 38. AJR Am J Roentgenol. A 10-year minimum followup study. and Murphy et al.). Femoral retroversion | definition of femoral retroversion by Medical dictionary femoral retroversion Also found in: Dictionary, Thesaurus, Encyclopedia. River Terrace 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 [19], Reikers et al. Conclusion Femoral antetorsion can be measured rapidly and with good reproducibility with MR imaging. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. The mean overall femoral version angles increased for hips with SCFE using more-distal landmarks compared with more-proximal landmarks. The data table on the chart reports the mean SD. This is the story of her diagnosis, operations and recovery to date: Hi I'm Elise and I live in Northern Ireland. Double plating for proximal humeral fractures (PHF) is an option to increase the primary fixation stability. Further measurement methods included the femoral head's center and differed regarding the level of landmarks for the proximal femoral reference axis. To rule out this potential bias, we measured leg abduction angle on coronal scout CT views between a line connecting the femoral head with the center of the femoral condyle relative to the neutral line connecting the tip of the coccyx with the pubic symphysis. 1956;88:3-41. 3). One radiology resident (6 years of experience) measured femoral version of the entire study group using five different methods. Femoral retroversion is often a congenital condition, meaning it is present from birth and develops in the womb. 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. Femoral retroversion is common in newborns because of contracture of the hip from intrauterine positioning. 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 2022 Oct;3(10):759-766. doi: 10.1302/2633-1462.310.BJO-2022-0102.R1. Murphy SB, Simon SR, Kijewski PK, Wilkinson RH, Griscom NT. Several factors, including obesity and a decreased femoral anteversion angle, have been associated with the development of slipped capital femoral epiphysis (SCFE) [31]. Out-toeing is the common name used for a condition known as femoral retroversion. J Bone Joint Surg Am. Definition of the distal femoral reference: the medial and lateral posterior condyles are connected. Children with femoral anteversion may trip and fall more than their peers, but the condition is rarely painful. 32. The .gov means its official. 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%]). government site. Gelberman RH, Cohen MS, Shaw BA, Kasser JR, Griffin PP, Wilkinson RH. For the definition of femoral neck version, the midpoint of the femoral neck axis is determined at the level where the cortices run parallel and serves as the proximal reference axis (Fig. J Pediatr Orthop. In some cases, hip/femoral retroversion may be combined with a separate torsional deformity, such as a rotation in the tibia. This may also make the legs look bowed. Liu RW, Armstrong DG, Levine AD, Gilmore A, Thompson GH, Cooperman DR. An anatomic study of the epiphyseal tubercle and its importance in the pathogenesis of slipped capital femoral epiphysis. Czech. Femoral retroversion is common in early infancy and is caused by external rotation contracture of the hip secondary to intrauterine packing. Level of evidence: 2017;11:284-288. [30] uses the center superior to the lesser trochanter at the base of the femoral neck as a landmark. Questions/purposes: 2012;470:3432-3438. J Bone Joint Surg Am. 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. 2015;31:247-253. 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. Further measurement methods included the femoral heads center and differed regarding the level of landmarks for the proximal femoral reference axis. Disclaimer, National Library of Medicine Akiyama M, Nakashima Y, Kitano T, et al. Request PDF | On Apr 6, 2015, Henry Knipe and others published Femoral retroversion | Find, read and cite all the research you need on ResearchGate The mean femoral neck version was lower in hips with SCFE than in the contralateral side (-2 13 versus 7 11; p < 0.001). Increasing femoral version angles with more-distal landmarks were observed in SCFE hips with and without previous in situ pinning alike (Table 5). All measurement methods are based on true axial images and a line connecting the femoral condyles as the distal reference axis. A modified Imhuser osteotomy: an assessment of the addition of an open femoral neck osteoplasty. Femoral anteversion causes the child's knees and feet to turn inward, or have what is also known as a "pigeon-toed" appearance. Femoral neck version was measured as the orientation of the femoral neck. Symptoms of femoral retroversion may include: If the doctor suspects a femoral retroversion, he will conduct a physical examination of the legs and hips in addition to a thorough medical, developmental and family history. For more information, please refer to our Privacy Policy. and Reikers et al.) After applying prespecified inclusion and exclusion criteria, we included 79 patients. 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). 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). 1979;86:420-428. SCFE and its complications may lead to lifelong disability encompassing pain, gait disturbances, degenerative changes, osteonecrosis and chondrolysis. 31. Future studies should compare femoral version in SCFE hips to age-matched volunteers without a history of hip disease. The orientation of the distal femoral condyles served as the distal reference axis for all five measurement methods. and most-distal methods (Tomczak et al. Coxa vara. Schmaranzer F, Lerch TD, Siebenrock KA, Tannast M, Steppacher SD. What are the causes of femoral retroversion? It is also known as 'Trochanteric Prominence Angle Test (TPAT)'. Most proximally (Lee et al. The condition is usually congenital, meaning children are born with it. The method of Reikers et al. Prevalence of femoral and acetabular version abnormalities in patients with symptomatic hip disease: a controlled study of 538 hips. 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. Surgical treatment of femoroacetabular impingement following slipped capital femoral epiphysis: a systematic review. This surgery includes cutting and realigning the femur. The effect of modality and landmark selection on MRI and CT femoral torsion angles. Oduwole KO, de SA D, Kay J, et al. This can cause pain and abnormal force in the hip and can lead to degeneration and arthritis. Hello friends, thankyou for watching my video, I am Physiotherapist with masters degree and working as Associate Professor in Mangalore.I love to teach and p. Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. (91% [95% CI 85% to 97%] and 84% [95% CI 76% to 92%], respectively) than for the distal measurement methods of Tomczak et al. Stanitski CL, Woo R, Stanitski DF. (47% [95% CI 36% to 58%] and 60% [95% CI 49% to 71%], respectively [all p < 0.001]). 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. 2020;14:98-105. J Bone Joint Surg Am. Background: 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. Please try after some time. Combined Imhauser osteotomy and osteochondroplasty in slipped capital femoral epiphysis through surgical hip dislocation approach. 29. 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]. . 2021 May 1;479(5):935-944. doi: 10.1097/CORR.0000000000001590. The retroversion was causing a minor curvature in my lumbar spine, tendinosis in my hamstring, and labral tears. Data is temporarily unavailable. 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. [30]: -4 16) (Fig. femoral retroversion synonyms, femoral retroversion pronunciation, femoral retroversion translation, English dictionary definition of femoral retroversion. , and. Fabricant PD, Bedi A, De La Torre K, Kelly BT. In patients with implant failure following in situ fixation, this included assessment of the femoral growth plate for planning of revision in situ fixation. In these situations, a surgical procedure known as a femoral osteotomy may be used. [30], a recent study reported a prevalence of femoral retroversion (< 0) of 5% and a mean femoral version of 19 14 in a cohort of 538 hips with femoroacetabular impingement, developmental dysplasia of the hip, and Perthes disease [22]. Patellofemoral joint pain is a very common knee problem physical therapists see in the clinic. Imhauser G. Pathogenesis and therapy of hip dislocation in youth [in German]. Unable to load your collection due to an error, Unable to load your delegates due to an error. Thus, this should not jeopardize the results of our study to a relevant degree. Femoral anteversion can occur in one or both legs. (3) What is the interobserver reliability and intraobserver reproducibility of these measurement methods? These side-by-side differences increased up to -22 (according to the method of Murphy et al. Limb Lengthening and Complex Reconstruction Service, out-toeing or "duck walk" walking with the foot pointed outward instead of straight ahead. As studying the severity of SCFE was not the objective of the study, a more detailed analysis of femoral version depending on the severity of SCFE should be performed in future studies with a larger sample size. Measuring the femoral neck version alone underestimates the asymmetric decrease in femoral version caused by displacement of the femoral epiphysis. and Murphy et al.). The five different measurement methods were applied in the same way in hips with SCFE and in healthy contralateral hips (Fig. All five methods were compared side-by-side (involved versus uninvolved hip), and comparisons among all five methods were performed using paired t-tests. Osteotomy to correct the alignment is rarely needed. 11. However, Koerner et al. 1987;69:1169-1176. Additionally, can femoral anteversion cause pain? femoral anteversion.
