Early and mid-range followup studies of shoulder arthroplasty have been encouraging, showing good and excellent results in > 90% of shoulders. Despite this success, complications in shoulder replacement surgery are inevitable, with an incidence of approximately 14%. Numerous complications have been identified and include the following factors in order of decreasing frequency: instability, rotator cuff tear, ectopic ossification, glenoid component loosening, intraoperative fracture, nerve injury, infection, and humeral component loosening. Successful treatment of these difficulties requires careful identification and subsequent analysis of all factors contributing to the complication, knowing that the etiology is often multifactorial. Failed shoulder arthroplasty can be successfully managed with revision surgery, but the technically challenging surgery and the overall results are inferior compared with other diagnostic categories.
肩关节置换术的早期和中期随访研究结果令人鼓舞，超过90%的肩关节取得了良好和优异的效果。尽管取得了这样的成功，但肩关节置换手术中的并发症仍不可避免，发生率约为14%。已确定了许多并发症，按发生频率从高到低依次包括以下因素：不稳定、肩袖撕裂、异位骨化、关节盂部件松动、术中骨折、神经损伤、感染和肱骨干部件松动。成功处理这些难题需要仔细识别并随后分析导致并发症的所有因素，因为病因往往是多因素的。失败的肩关节置换术可通过翻修手术成功处理，但与其他诊断类别相比，该手术技术难度大且总体效果较差。
