Total joint replacement in the upper extremity has developed in step with that of the lower extremity. The indications for treatment, the place of total joint arthroplasty in contrast to other forms of arthroplasty, and the criteria for patient selection have recently been classified. A number of problem areas are under biomechanical and clinical study, and most investigators are proceeding cautiously. In properly selected patients, however, prosthetic replacement offers great improvement in both relief of pain and joint function, and improvement should continue. The patient and physician should recognize the limitations that are inherent in any "artificial joint" replacement. Realistic expectations would be for improvement that approaches, but rarely achieves, normal function.
上肢全关节置换术与下肢全关节置换术同步发展。治疗指征、全关节置换术相对于其他关节置换形式的地位以及患者选择标准最近已得到分类。一些问题领域正在进行生物力学和临床研究，大多数研究者都在谨慎推进。然而，在选择恰当的患者中，假体置换在缓解疼痛和改善关节功能方面都有很大改善，并且这种改善应该会持续。患者和医生应该认识到任何“人工关节”置换所固有的局限性。现实的期望是接近但很少能达到正常功能的改善。
