: The goal of this study was to evaluate the functional outcomes of patient treatment using an allograft after chronic locked posterior shoulder dislocation associated with a bony defect of the upper edge of the humerus that involves 25-50% of the articular surfaces. : A total of 20 patients were included in this study. Electrocution was the cause of injury in eight patients; in ten patients, the cause was direct trauma; and in two patients, the cause of injury was a fall due to hypoglycemic coma. A standard deltoid pectoral approach was used and a fresh-frozen osteochondral allograft of the femoral condyle was applied. In evaluating the results, Constant's scoring scale was used. : The average value of Constant's point scale for the operated shoulder is 84.14 points. This result is good according to the average value of Constant's point scale. : Patients with locked chronic posterior dislocation in combination with a bony defect of the humeral head that covers 25-50% of the articular surface, in our opinion, should be treated using bone allografts rather than non-anatomical reconstruction methods.
本研究的目的是评估慢性锁定性后肩脱位患者使用同种异体移植物治疗的功能结果，该患者伴有肱骨上缘骨缺损，涉及 25-50%的关节面。
共有 20 名患者纳入本研究。8 名患者的损伤原因为电击伤；10 名患者的损伤原因为直接创伤；2 名患者的损伤原因为低血糖昏迷引起的跌倒。采用标准三角肌胸大肌入路，应用新鲜冷冻股骨髁骨软骨同种异体移植物。在评估结果时，使用了 Constant 评分量表。
手术肩的 Constant 评分平均值为 84.14 分。根据 Constant 评分平均值，这个结果是良好的。
我们认为，对于伴有覆盖 25-50%关节面的肱骨头部骨缺损的慢性锁定后脱位患者，应采用骨同种异体移植物治疗，而不是采用非解剖重建方法。
