Twenty-six patients, 11 with rheumatoid arthritis and 15 with osteoarthritis, have been operated on with an unconstrained total shoulder arthroplasty. Mean follow-up was 47 months. Three prostheses have been extracted. All patients stated that they had pain relief after surgery. At three year follow-up all except one had developed radiolucent zones around the glenoid component. No zones were observed around the humeral component. In shoulders with preserved glenoid surface replacement of only the humeral head might provide better long-term results than a total shoulder arthroplasty.
26例患者接受了非限制性全肩关节置换术，其中11例患有类风湿性关节炎，15例患有骨关节炎。平均随访时间为47个月。已取出3个假体。所有患者均表示术后疼痛缓解。在三年随访时，除1例患者外，其余所有患者的肩胛盂假体周围均出现了透亮区。肱骨头假体周围未观察到透亮区。对于肩胛盂表面保留的肩关节，单纯肱骨头置换可能比全肩关节置换提供更好的长期效果。
