This article describes a modified lightbulb technique, which perfects the method, the instrument, and the flap used in order to ensure hip musculature preservation and improved outcomes. With the direct anterior approach, there is no need to perform surgical dislocation, so the time of the surgery is reduced, as well as the risk of vascular injury. The necrotic bone can be precisely removed using custom-made offset curettes, and a bone graft substitute and autograft can be placed under C-arm guidance. This technique may be beneficial in treating early osteonecrosis of the femoral head by reducing operative time and reducing the risk of complications related to surgical dislocation.</p>","PeriodicalId":48583,"journal":{"name":"Journal of Hip Preservation Surgery","volume":"13 1","pages":"56-59"},"PeriodicalIF":1.1,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12891994/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146182582","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}

While arthroplasty is rarely indicated for patients with preserved joint space, it may be the preferred surgical option when advanced imaging reveals severe intra-articular pathology. The purpose of this study was to evaluate a semiquantitative MRI-based scoring system in patients undergoing surgery for hip pain without advanced radiographic joint space loss. Consecutive patients with hip pain refractory to conservative measures and without severe radiographic hip osteoarthritis [Tönnis grade 0-1, Joint Space Width (JSW)> 3 mm] who received primary total hip arthroplasty with a preoperative MRI were included. This cohort was propensity-matched by Tönnis grade and JSW, as well as age, gender, and BMI, to patients undergoing hip preservation surgery. Preoperative MRIs were evaluated according to the Scoring Hip Osteoarthritis with MRI (SHOMRI) grading system. SHOMRI scores were compared between the arthroplasty and hip preservation cohorts with threshold values calculated to evaluate associations with treatment pathways. Patients undergoing arthroplasty had significantly greater SHOMRI total scores as well as cartilage component scores. Threshold values for the cartilage component SHOMRI score were significantly associated with the designated surgical treatments between the two groups (<i>P</i> < .001). Subjects in each treatment group had significant postoperative improvement to the 2-year time point with high postoperative satisfaction, indicating appropriate treatment designation. Application of SHOMRI scoring thresholds may decrease subjectivity in surgeon decision making when using advanced imaging in patients without significant radiographic osteoarthritis.</p>","PeriodicalId":48583,"journal":{"name":"Journal of Hip Preservation Surgery","volume":"12 4","pages":"256-264"},"PeriodicalIF":1.1,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12712967/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145805834","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 computed tomography data from 50 patients were reconstructed, and the FNA was fitted by the centroid iterative method. The fitting accuracy was evaluated in terms of the distance between the femoral head centre and the FNA. The reliability was assessed by intraclass correlation coefficient (ICC). Stress-strain distributions of the native femur model and rotational osteotomy models with accurate FNA and deviated FNA were simulated by finite element analysis and digital image correlation methods. The distance between the femoral head centre and the FNA was 1.24 ± 0.35 mm. The intra- and interobserver reliability was high, with ICC values of 0.960 and 0.924, respectively.

We enrolled 12 patients (12 hips) post-RAO and 15 patients (15 hips) post-SPO who consented to undergo computed tomography (CT) imaging about 5 weeks after surgery. Results showed no significant differences in lateral centre-edge angle or acetabular roof obliquity between these groups, both before and after surgery.

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.
