Survivorship and survival rate of shoulder prostheses can be affected by a large number of possible complications. An evaluation of the current literature and the prosthesis register, however, shows an overall low revision (1.39 revisions per 100 observation years) and loosening rates (implant-related 10-year survival rate up to 99%), comparable to that of hip and knee endoprostheses. It must be emphasized that cementless stems more often cause problems than cemented components (4.34 compared to 0.77 revisions per 100 observation years) and that secondary rotator cuff rupture (4.6%; functional deficit up to 30%) occurs more frequently than was generally assumed and is often not diagnosed or treated adequately. The infection rate amounts to approximately 1% and according to latest literature the dislocation rate is regressive and is estimated to be approximately 5%.The low complication and revision rates do not justify the replacement of stemmed prostheses by stemless implants and short stem prostheses and the preference given to the new implants is attributed more to the better revision possibilities and easier convertibility into inverse prostheses.
肩部假体的生存率和存活比率可能受到大量潜在并发症的影响。然而,对当前文献和假体登记数据的评估显示,总体翻修率较低(每100观察年有1.39次翻修),松动率也较低(与植入物相关的10年生存率高达99%),与髋关节和膝关节假体相当。必须强调的是,非骨水泥柄比骨水泥部件更常引发问题(每100观察年分别为4.34次和0.77次翻修),并且继发性肩袖破裂(发生率为4.6%;功能缺陷高达30%)比通常认为的更为常见,且常常未得到充分诊断或治疗。感染率约为1%,根据最新文献,脱位率呈下降趋势,估计约为5%。低并发症率和翻修率并不能成为用无柄植入物和短柄假体取代有柄假体的理由,对新型植入物的青睐更多地归因于更好的翻修可能性以及更容易转换为反向假体。
