However, different measurement methods for FV and different normal values are confusing. The study aimed to investigate differences in FV measurement methods and to review normal FV. This retrospective comparative study investigated a total of 84 hips for FV measurement: 48 hips (asymptomatic patients) and 36 hips (asymptomatic volunteers) without hip pain. The 48 patients underwent computed tomography (CT) for another reason (mean age 63 ± 11 years) and most (39 hips, 81%) were male patients. The 36 hips reported no hip pain at the time of magnetic resonance imaging (MRI) (mean age 27 ± 7 years, 20 female patients, 56%). FV was measured on CT or MRI included pelvis and knee) and with the Murphy method. Mean FV for 48 hips was 22° (range 5-34°), and for 36 hips, it was 24° (7-44°). No significant differences were found between the two groups. For 39 male patients with CT scans, the mean FV was 21° (6-34°) and was significantly (P = 0.041) decreased compared to female patients (FV of 26°). For the review, 18 studies were compared that evaluated normal FV (total of 2275 hips) in the literature. Increasing values for normal FV were found for measurement methods with a more distal definition of the femoral neck axis: Normal values were reported for the Lee method (most proximal definition; 8-11°), Reikeras method (9-20°), Oblique/Jarrett method (9-15°), Tomczak method (22-24°), and Murphy method (most distal: 18-23°). Reported normal range of FV differs between measurement methods. This is important for patients with FAI/hip dysplasia undergoing hip preservation surgery (hip arthroscopy/femoral derotation osteotomy).","PeriodicalId":48583,"journal":{"name":"Journal of Hip Preservation Surgery","volume":"12 3","pages":"157-163"},"PeriodicalIF":1.1,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12461209/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145187327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to use finite element analysis to assess LT stress during hip movements, which included external rotation with flexion. A 3D model of the hip joint, including the femoral head and LT, was constructed from magnetic resonance imaging data using 3D Slicer. The models were imported into Ansys SpaceClaim 2022R1 for refinement and assembly. The von Mises stress in the LT was extracted during six hip movements: external rotation, internal rotation, abduction, adduction, flexion, and extension. LT stress response was also extracted during external rotation at hip flexion angles of 0°, 30°, 60°, and 90°. The results found there was a sharper increase in LT stress during movements involving hip external rotation, internal rotation, abduction, and adduction when compared to movements in flexion and extension. External rotation in larger hip flexion angles resulted in greater LT stress, with the highest stress observed at 90° flexion. These findings help to support the LT's role as a rotational stabilizer in the frontal and transverse planes wrapping around the femoral head to act as a sling. Additionally, the increased stress during external rotation at greater degrees of hip flexion suggests an enhanced role for the LT in hip stability as flexion increases. These results add as a proof of concept in that the LT is under stress during hip movements and has a potential role in stabilizing the hip joint.","PeriodicalId":48583,"journal":{"name":"Journal of Hip Preservation Surgery","volume":"12 3","pages":"181-185"},"PeriodicalIF":1.1,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12461197/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145187396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developmental dysplasia of the hip (DDH) and femoroacetabular impingement (FAI) represent key pathologies, resulting from insufficient or excessive femoral head coverage, respectively. These abnormalities alter hip biomechanics, leading to structural damage, pain, and accelerated joint degeneration. Advances in genetic research have illuminated the interplay between genetics and mechanical loading in shaping hip morphology. Genes associated with osteoarthritis, DDH, and FAI include COL1A1, MMP13, and IL-6. Genes associated with FAI and osteoarthritis include ADAMTS4. Genes associated with DDH and osteoarthritis include FRZB, CX3CR1, ASPN, DKK1, PDRG1, GDF5, UQCC1, and TGF-β1. The mechanisms linking morphological derangements to symptomatic osteoarthritis remain incompletely understood. Multimodal approaches integrating imaging, biomechanics, and genetics may uncover distinct disease subtypes, enabling personalized interventions. Early detection of MHAs is critical in preventing early-onset osteoarthritis. Incorporating advanced imaging techniques, such as statistical shape modelling, can enhance the understanding of complex 3D hip morphologies and their progression to osteoarthritis. Future research should explore the genetic underpinnings of other morphologic hip conditions, including Slipped Capital Femoral Epiphysis and Legg-Calvé-Perthes disease, to refine preventive and therapeutic strategies. A comprehensive approach combining genetics, imaging, and clinical insights holds promise for mitigating the lifelong impact of MHAs.","PeriodicalId":48583,"journal":{"name":"Journal of Hip Preservation Surgery","volume":"12 3","pages":"202-216"},"PeriodicalIF":1.1,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12461200/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145187351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Femoral anteversion varies among patients; however, the osteotomy design on the axial plane in CVO has not been well investigated. This study evaluated the variation in the osteotomy angle on the axial plane in a CVO and its effect on the postoperative intact ratio, which determines the postoperative outcome. This study included 10 patients with Type C1 ONFH who underwent CVO according to the Japanese Investigation Committee classification. The osteotomy angles relative to the posterior condylar and femoral neck axes on the axial plane were measured on postoperative computed tomography images. The progression of collapse and osteoarthritic change were reviewed on serial radiographs. The mean osteotomy angles to the posterior condylar axis and the femoral neck axis were 0.2° and 15.3°, respectively. The mean postoperative intact ratio was 45.6% (range: 28.0-62.8%). The osteotomy angle to the femoral neck axis was significantly and negatively correlated with the postoperative intact ratio (ρ = -0.782, P = .008). In three cases, the osteotomy line was directed >25° anteromedial to the femoral neck axis, and the postoperative intact ratio was less than the target (34%); one showed progression of the collapse of the femoral head, and another an osteoarthritic change. We observed wide variations in the osteotomy angle on the axial plane during manually performed CVO. The osteotomy angle to the femoral neck axis on the axial plane affected the postoperative intact ratio.","PeriodicalId":48583,"journal":{"name":"Journal of Hip Preservation Surgery","volume":"12 3","pages":"175-180"},"PeriodicalIF":1.1,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12461204/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145186424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
