Eighteen patients had prosthetic proximal humeral replacement with either a metal or ceramic prosthesis. Three replacements were performed for fracture nonunions, five for benign neoplasms, six for low-grade malignancies, and four for high-grade malignancies. Retention of elbow and hand function was good. In five of the 11 ceramic prostheses, failure occurred at the humeral-prosthetic junction even though it was designed for biologic fixation. Ten of 18 prostheses subluxated or dislocated. Twelve of 18 patients have had revision operations. While the revision rate in this initial series was high, valuable experience was gained for further investigations of shoulder arthroplasty.
18例患者接受了金属或陶瓷假体的肱骨近端置换术。其中3例用于治疗骨折不愈合，5例用于治疗良性肿瘤，6例用于治疗低度恶性肿瘤，4例用于治疗高度恶性肿瘤。肘部和手部功能保留良好。在11个陶瓷假体中，有5个在肱骨-假体连接处出现了故障，尽管其设计为生物固定。18个假体中有10个发生半脱位或脱位。18例患者中有12例接受了翻修手术。虽然这个初始系列的翻修率很高，但为进一步研究肩关节置换术积累了宝贵的经验。
