A 38-year-old female presented with significant pain and limited active and passive range of motion of the left shoulder following a traumatic anterior shoulder dislocation. MRI revealed full-thickness retracted tears of the entire cuff as well as a posterolateral LHBT dislocation. The patient underwent an initial open repair of the shoulder and long head of biceps tenodesis. At 5 months follow-up, MRI confirmed a full-thickness re-tear of the supraspinatus, infraspinatus, and subscapularis tendons. Patient subsequently underwent a combined open transfer of the lower trapezius tendon to the greater tuberosity and the latissimus dorsi to the lesser tuberosity. At the final, one-year, postoperative follow-up, the patient exhibited improvements in pain and stability, though continued to experience ongoing range of motion and strength limitations. This report provides a comprehensive review of 12 previous reports describing posterior LHBT dislocation. Among the limited literature on posterior LHBT dislocation, only one case exhibited a posterior LHBT in the context of a MRCT similar to that described in this report. The combination of an unusual occurrence of a posterior LHBT dislocation in the context of a MRCT involving full thickness tears of the supraspinatus, infraspinatus, subscapularis, and teres minor tendons, is rarely documented, making this case report both clinically challenging and unique.</p>","PeriodicalId":21783,"journal":{"name":"Skeletal Radiology","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144258929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Continuous coronal-slice hematoxylin and eosin-stained specimens of each femoral head were examined for the presence of subchondral fracture. Bone microarchitectures around subchondral fractures were measured using micro-computed tomography (CT) images.</p><p><strong>Results: </strong>In all femoral heads, subchondral fractures were histopathologically confirmed at the lateral junction between the reparative and the necrotic zone. On micro-CT, bone volume fraction, trabecular thickness, and bone mineral density of the reparative zone adjacent to the subchondral fracture were all significantly higher than those of the necrotic zone adjacent to the subchondral fracture.</p><p><strong>Conclusion: </strong>Subchondral fracture invariably existed when bone marrow edema was present on MRI during pre-collapse osteonecrosis of the femoral head. When bone marrow edema is observed on MRI, it should be known that subchondral fracture has already occurred, even if femoral head collapse is unclear on radiographs.</p>","PeriodicalId":21783,"journal":{"name":"Skeletal Radiology","volume":" ","pages":"1275-1281"},"PeriodicalIF":1.9,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142751616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
