This study reviews the second case in the literature involving the use of frozen osteochondral allograft to reconstruct a femoral head fracture-dislocation. The case involved significant, unreconstructable damage to the weightbearing area of the femoral head in an 18-year-old male. Clinical and diagnostic imaging follow up at 46 months revealed that despite magnetic resonance imaging and radiographic evidence of progressive arthrosis in the hip, including subchondral cystic change in the femoral head and localized cartilage loss in the acetabulum and femoral head, the patient had excellent function with no complications (Harris hip score 100, hip dysfunction and osteoarthritis outcome score 62, musculoskeletal function assesment score 22, SF-36 score 81). The use of osteochondral allograft may serve as a useful tool for the orthopaedic surgeon faced with an unreconstructable femoral head fracture-dislocation in a young patient.
本研究回顾了文献中涉及使用冷冻同种异体骨软骨移植重建股骨头骨折脱位的第二例病例。该病例涉及 18 岁男性股骨头承重区严重、无法重建的损伤。46 个月的临床和诊断影像学随访显示，尽管髋关节磁共振成像和影像学显示进行性关节炎证据，包括股骨头的软骨下囊性改变和髋臼及股骨头的局部软骨丢失，但患者功能极佳，无并发症（Harris 髋关节评分 100，髋关节功能和骨关节炎结局评分 62，肌肉骨骼功能评估评分 22，SF-36 评分 81）。对于年轻患者面临无法重建的股骨头骨折脱位的骨科医生来说，使用骨软骨同种异体移植可能是一种有用的工具。
