We reexamined 19 shoulder hemiarthroplasties in patients with rheumatoid arthritis after a mean of 8 (1-17) years. For the evaluation, we used the Constant and Murley score and routine radiographs. At the follow-up examination, 12 of the 19 shoulders showed little, if any, pain. In 7 shoulders the pain was moderate and no patient had severe pain. The range of motion was not improved. In 7/18 shoulders proximal subluxation of the head of the humeral prosthesis and in 9/15 shoulders, progression of the glenoid erosion were seen. The increase in glenoid erosion and the postoperative pain were not correlated. Hemiarthroplasty of the shoulder effectively relieves the pain in rheumatoid patients and this seems long-lasting.
我们对19例类风湿性关节炎患者的肩关节半关节成形术进行了复查，平均随访时间为8年（1至17年）。为进行评估，我们采用了Constant和Murley评分以及常规X线片。在随访检查中，19个肩关节中有12个几乎没有疼痛（即便有也很轻微）。7个肩关节有中度疼痛，没有患者有重度疼痛。活动范围没有改善。在18个肩关节中有7个出现了肱骨头假体近端半脱位，在15个肩关节中有9个出现了关节盂侵蚀进展。关节盂侵蚀的加重与术后疼痛并无关联。肩关节半关节成形术能有效缓解类风湿患者的疼痛，且这种缓解似乎是持久的。
