This condition is diagnosed in childhood, and is characterized by the unusual "duck feet" posture and walk that the child develops. The five different measurement methods were applied in the same way in hips with SCFE and in healthy contralateral hips (Fig. This graph shows a comparison of the different methods to measure femoral version for hips with SCFE and contralateral hips. After applying prespecified inclusion and exclusion criteria, we included 79 patients. J Child Orthop. 1997;168:791-794. 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). 12. Results: The mean age at the time of CT was 15 4 years. Chadayammuri V, Garabekyan T, Bedi A, et al. 2020;30:5281-5297. 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). and Murphy et al.). Akiyama M, Nakashima Y, Kitano T, et al. To facilitate communication among physicians and for the design of future studies, we recommend consistently reporting the applied measurement technique. Diagnosing femoral retroversion can sometimes be difficult, as the common positioning for X-ray imaging may not reveal a rotation in the femoral neck. Using the four alternative measurement techniques that are based on the center of the femoral head as a proximal reference, the mean differences between the affected and contralateral side were higher. 19. 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. More specifically, the prevalence of femoral retroversion was higher in hips with SCFE for the proximal methods of Lee et al. 2019;43:2375-2382. A comprehensive analysis of femoral version may provide valuable baseline information to optimize surgical planning in hips with sequalae of SCFE and to allow standardization of studies investigating surgical correction of SCFE deformities. Mechanical risk factors for SCFE include rapid growth spurts, femoral retroversion, and femoral neck shaft angle. Combined Imhauser osteotomy and osteochondroplasty in slipped capital femoral epiphysis through surgical hip dislocation approach. Arthroscopy. Femoral retroversion causes hip impingement, similar to the impingement and posterior instability that occurs in total hip arthroplasty. , . (1) Do femoral version and the prevalence of femoral retroversion differ between hips with SCFE and the asymptomatic contralateral side? A 10-year minimum followup study. 2014;96:1119-1123. The hip joint and psoas muscle lie directly deep to the femoral . Of the 754 patients diagnosed with SCFE between 2000 and 2017, 172 patients had undergone pelvic CT scans. American Heritage Dictionary of the English Language, Fifth Edition.. FOIA J Orthop Res. Acetabular retroversion has been proposed to contribute to the development of osteoarthritis of the hip. A turning or tilting backward. 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). Congenital right femoral retroversion; Congenital right hip dysplasia; Present On Admission. And if left untreated into adolescence, these abnormal femoral rotations can also contribute to the degeneration or arthritis of the hip. [44] and Murphy et al. FEMORAL VEIN ANATOMY. Femoral version by measurement method and by side (affected versus contralateral) was summarized using the mean, SD, and 95% confidence interval. n. 1. We detected mean differences ranging from -19 to 4 (all p < 0.005) for 8 of 10 pairwise comparisons in hips with SCFE. femoral retroversion (___ degrees), femoral retroversion (physical finding), femoral retroversion, Femoral retroversion. Femoral anteversion causes the child's knees and feet to turn inward, or have what is also known as a "pigeon-toed" appearance. J Orthop Trauma. Torsional deformity can also occur after a fracture where the bone heals with deformity or malunion. 18. [35]. 32. [35] (91% [95% CI 85% to 97%] and 84% [95% CI 76% to 92%], respectively) than for the distal measurement methods of Tomczak et al. We also compared isolated femoral neck version with aligning the orientation of the femoral neck with the femoral head center to define the proximal reference, as described by Reikers et al. 2019:47:3120-3132. Thus, a normal rotation between the hip and the knee is established, correcting the torsional deformity. Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. The effects of simulated microgravity on the static and dynamic properties of large arteries are still mostly unknown. Femoral anteversion is an inward twisting of the thigh bone (femur). Femoral Retroversion. (3) What is the interobserver reliability and intraobserver reproducibility of these measurement methods? External tibial torsion. [19]) compared with distal landmarks to define the femoral reference axis (47% for the method of Tomczak et al. Osteotomy through the lesser trochanter for slipped capital femoral epiphysis. (47% [95% CI 36% to 58%] and 60% [95% CI 49% to 71%], respectively [all p < 0.001]). 2017;11:93-98. 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. Additionally, can femoral anteversion cause pain? to -22 13 (95% CI -25 to -19; p < 0.001) according to the method of Murphy et al. Copyright 2020 by the Association of Bone and Joint Surgeons. In many cases, the abnormal rotation of the femur develops while the fetus is growing in the womb. 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. The most significant clinical implication of femoral retroversion is that it is not soft tissue-related. The physician may also order an X-ray or CT scan to look for possible deformities. One radiology resident (6 years of experience) measured femoral version of the entire study group using five different methods. Doing so may better inform surgeons as they contemplate when to use isolated offset correction or perform an addional femoral osteotomy for SCFE correction based on the severity of the slip and the rotational deformity. English. 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). We detected mean differences ranging from -19 to 4 (all p < 0.005) for 8 of 10 pairwise comparisons in hips with SCFE. Disclaimer, National Library of Medicine A preoperative 3D-CT-scan was performed for 3D simulation of hip impingement ( Fig. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. 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. and Reikers et al. By contrast, Stanitski et al. Tnnis D, Heinecke A. Acetabular and femoral anteversion: relationship with osteoarthritis of the hip. [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]. The torsional deformity is corrected by re-establishing the normal rotation between the hip and the knee. Wolters Kluwer Health The articular cartilage is intact. Among 10 possible pairwise combinations, we detected differences for 8 pairwise comparisons in hips with SCFE (Table 4). Furthermore, the prevalence of actual femoral retroversion and the effect of different measurement methods has yet to be studied in SCFE. Southwick WO. This means thehip is twisted backward (posteriorly) in relation to the knee. These differences ranged from -17 11 (95% CI -20 to -15; p < 0.001) based on Tomczak et al.s [44] method to -22 13 (95% CI -25 to -19; p < 0.001) when applying Murphy et al.s [30] method (Fig. 39. Thus, to assess the full extent of an SCFE deformity, femoral version measurements should consider the position of the displaced epiphysis. 7. The condition is usually congenital, meaning children are born with it. method), we used the most cephalic junction of the greater trochanter as the landmark and, most distally, we used the center base of the femoral neck superior to the lesser trochanter (Murphy et al.). 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). 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). Unable to load your collection due to an error, Unable to load your delegates due to an error. 1988;8:385-388. The site is secure. [18] reported normal femoral neck version of 8.8 9.7 in 328 hips without radiographic signs of osteoarthritis. Some abnormalities may resolve spontaneously. . Out-toeing is the common name used for a condition known as femoral retroversion. Time from SCFE diagnosis to CT was 1.8 2.5 years (Table 1). [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]. 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. 1956;88:3-41. Twenty-nine percent (23 of 79) of patients had no previous surgical treatment for SCFE. 22. This is also called in-toeing. J Bone Joint Surg Am. At a mean follow-up of 58 46 months, the femoral growth plate was closed in 95% (75 of 79) of patients. 2017;21:487-506. Initial diagnosis of unilateral SCFE was based on an absence of radiographic signs of SCFE and of pain at clinical examination. In these situations, a surgical procedure known as a. may be used. 3). 2016;98:127-134. J Bone Joint Surg Am. Erickson JB, Samora WP, Klingele KE. Accordingly, the methods of Lee et al. Doing so may better inform surgeons as they contemplate when to use isolated offset correction or to perform an additional femoral osteotomy for SCFE correction based on the severity of the slip and the rotational deformity. 46. 8600 Rockville Pike Fabricant PD, Fields KG, Taylor SA, Magennis E, Bedi A, Kelly BT. The retroversion was causing a minor curvature in my lumbar spine, tendinosis in my hamstring, and labral tears. Some error has occurred while processing your request. 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. Increased BMI leads to an increase in simulated loads across the physis [33] and may be further aggravated by retroversion of the femoral neck, which has been associated with obesity [14]. The minimum slice thickness was 2 mm. . While both femoral anteversion and retroversion do not always cause discomfort, they can eventually bring about pain in the lower back, hip, and knee. Federal government websites often end in .gov or .mil. Gelberman et al. Bali NS, Harrison JO, Bache CE. Unlike in- toeing, out-toeing may lead to pain and disability as the child grows into adulthood. (2) These formulae facilitate preparation of computer programs and tables for the routine clinical determination of the anteversion and cervico-diaphyseal angles. This surgery includes cutting and realigning the femur. In healthy contralateral hips, we found differences for 9 of 10 pairwise comparisons (Table 4). Bone Joint J. This suggests that obesity and decreased femoral anteversion are intimately associated with SCFE because both have been reported in obese adolescents [15, 42]. Medial joint line: medial meniscus, medial femoral condyle, and tibial and femoral insertions of the medial collateral ligament (MCL). 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 retroversion synonyms, femoral retroversion pronunciation, femoral retroversion translation, English dictionary definition of femoral retroversion. Rebello G, Spencer S, Millis MB, Kim Y-J. 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. , and. Femoral anteversion is usually most noticeable in children between the ages of 4 and 6. 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. A pathological increase in angle of torsion is called femoral anteversion, and a pathological decrease in the angle or reversal of torsion is known as femoral retroversion. 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). femoral anteversion. . An important mark of this deformity is the reduced or absent offset between the femoral head and the neck, which can be radiographically graded. Loder RT, Aronson DD, Greenfield ML. The I-bars represent the corresponding 95% CI. 36. 9. [30] uses the center superior to the lesser trochanter at the base of the femoral neck as a landmark. Double plating for proximal humeral fractures (PHF) is an option to increase the primary fixation stability. In the axial HASTE images over the proximal and distal femur a femoral retroversion can be seen, i.e. 2) and hip ROM [ 32, 33 ]. 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. The data table on the chart reports the mean SD. This surgery includes cutting and realigning the femur. Femoral retroversion can occur in one or both legs. Femoral retroversion is common in early infancy and is caused by external rotation contracture of the hip secondary to intrauterine packing. Out-toeing may be caused by: Femoral retroversion. Bali K, Railton P, Kiefer GN, Powell JN. 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. 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]. (47% [95% CI 36% to 58%] and 60% [95% CI 49% to 71%], respectively [all p < 0.001]). 2). Questions/purposes: J Child Orthop. 2021 May 1;479(5):935-944. doi: 10.1097/CORR.0000000000001590. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. Bone Joint J. femoroacetabular impingement. Femoral anteversion can occur in one or both legs. Ethical approval for this study was obtained from the institutional review board of Boston Childrens Hospital (protocol number IRB-P00018761). Tomczak et al.s [44] method uses the center of the base of the greater trochanter as a landmark. Tomczak RJ, Guenther KP, Rieber A, Mergo P, Ros PR, Brambs HJ. Any treatment of my symptoms was going to be ineffective due to the alignment still being off. Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. J Child Orthop. Future studies should compare femoral version in SCFE hips to age-matched volunteers without a history of hip disease. To facilitate communication among physicians and for the design of future studies, we recommend consistently reporting the applied measurement technique. During this time period, 754 patients were diagnosed with SCFE. "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? Liu RW, Fraley SM, Morris WZ, Cooperman DR. Validity and clinical consequences of a rotational mechanism for slipped capital femoral epiphysis. The condition is usually congenital, meaning children are born with it. . 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). The condition is usually congenital, meaning children are born with it. Furthermore, the reliability and reproducibility of these measurements in patients with SCFE is unknown. What Is the Association Among Epiphyseal Rotation, Translation, and the Morphology of the Epiphysis and Metaphysis in Slipped Capital Femoral Epiphysis? 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. Femoral neck version was measured as the orientation of the femoral neck. Schmaranzer F, Kallini JR, Miller PE, Kim Y-J, Bixby SD, Novais EN. Accordingly, the mean difference between these two measurement techniques was as high as -19 7 (Table 4). Femoral version of the general population: does normal vary by gender or ethnicity? SELECTED PROCEEDINGS FROM THE 2020 BERNESE HIP SYMPOSIUM GUEST EDITOR: KLAUS-ARNO SIEBENROCK MD. 44. 13. The greatest differences were between measurement methods that are based on the most-proximal landmarks and those based on the more-distal landmarks. 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 . 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. We found that femoral neck version is asymmetrically decreased by -8 in unilateral hips with SCFE compared with contralateral hips. Arthroscopy. The femur bone is cut through a portal and an intramedullary rod is inserted into the marrow cavity of the bone. 20. [19] method -19 16 [95% CI -25 to -12] versus -19 16 [95% CI -23 to -15]; p = 0.90, respectively) (Table 5). Request PDF | On Apr 6, 2015, Henry Knipe and others published Femoral retroversion | Find, read and cite all the research you need on ResearchGate 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). 35. 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). These side-by-side differences increased up to -22 (according to the method of Murphy et al. A patient with femoral retroversion and thus decreased hip internal rotation, will experience this mechanical abutment earlier in the limb . Therefore, quantifying femoral version in patients with SCFE should be based on a measurement technique that includes the femoral rotations center. official website and that any information you provide is encrypted Coxa valga and antetorta increases differences among different femoral version measurements : potential implications for derotational femoral osteotomy planning. 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. Routinely measuring femoral version might help surgeons better identify which part of an abnormal femur (cam deformity and/or externally rotated femur) should be corrected. Approach to the hip for SCFE: the North American perspective. Please try after some time. 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%]). 15. 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. A specialist will observe your . Symptoms of femoral retroversion may include: If femoral retroversion is suspected, a doctor will do a physical examination of the legs and hips in addition to a thorough medical, developmental and family history. MR imaging measurement of the femoral antetorsional angle as a new technique: comparison with CT in children and adults. Femoral version in acute slipped capital femoral epiphysis. to maintaining your privacy and will not share your personal information without Lerch TD, Novais EN, Schmaranzer F, et al. Retroversion refers to an abnormal backward rotation of the hip relative to the knee. In some cases, hip/femoral retroversion may be combined with a separate torsional deformity, such as a rotation in the tibia. External rotation contracture of the hip. Am J Sports Med. It is also known as 'Trochanteric Prominence Angle Test (TPAT)'. 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. 2006;44:895-906. 2020;14:98-105. CORR Insights: How Common Is Femoral Retroversion and How Is it Affected by Different Measurement Methods in Unilateral Slipped Capital Femoral Epiphysis? For those who do not, a mild case may not cause significant health problems. We performed a subgroup analysis, and with the numbers available, we observed any differences in femoral version angles between patients with and without previous in situ fixation (Table 5). 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. The doctor will also observe the patients gait (manner of walking) to look for signs of out-toeing or gait compensation. and Reikers et al.) The mean overall femoral version angles increased for hips with SCFE using more-distal landmarks compared with more-proximal landmarks. Many children born with femoral retroversion grow out it. 2013;27:308-311. Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. The Lisbon agreement on femoroacetabular impingement imaging-part 1: overview. (2) How do the mean femoral version angles and the prevalence of femoral retroversion change depending on the measurement method used? Femoral retroversion often runs in families, which may indicate that some children have a higher risk of being born with this condition. She was treated with an open reduction and bracing in infancy. Differences in femoral torsion among various measurement methods increase in hips with excessive femoral torsion. 2019;477:1111-1122. 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. 1967;49:807-835. More distally, the pes anserinus bursa should be palpated for tenderness typical of pes . The .gov means its official. 1987;69:1169-1176. You may notice that your child is walking with the toes turned inward. Berryman F, Pynsent P, McBryde C. A semi-automated method for measuring femoral shape to derive version and its comparison with existing methods. Prevalence of femoral and acetabular version abnormalities in patients with symptomatic hip disease: a controlled study of 538 hips. An official website of the United States government. Mechanical factors in slipped capital femoral epiphysis. Children with femoral anteversion may trip and fall more than their peers, but the condition is rarely painful. It becomes apparent as the child starts to stand or cruise between 6 and 9 months. 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 Please enable it to take advantage of the complete set of features! 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. 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. [42] found higher mean femoral neck version of 9.3 in seven patients (five with obesity) with unilateral SCFE. 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
