There is a lack of organization in existing studies on the outcome and complications of total shoulder arthroplasty. As a result, it is difficult to gain substantial evidence regarding the rate and risk factors for the occurrence of glenoid loosening which remains the most common cause of prosthetic failure. To improve the quality of future studies, an agreement should exist on definitions of glenoid loosening and on the potential risk factors.
Reviewing the literature, loosening can be defined as the appearance of radiolucent lines, radiological loosening, clinical loosening and revision as the end stage. Three different categories of influencing parameters can be distinguished: implant related, patient related and surgeon related. Expert commentary: The aim of this review is to organize the available knowledge on glenoid failure, as well as to describe the gaps so that it will constructively contribute to the debate on how to prevent glenoid failure in the anatomic total shoulder arthroplasty.
现有关于全肩关节置换术的结果和并发症的研究缺乏系统性。因此，难以获得关于肩胛盂松动发生率及危险因素的充分证据，而肩胛盂松动仍是假体失败最常见的原因。为提高未来研究的质量，应就肩胛盂松动的定义及潜在危险因素达成共识。
回顾文献可知，松动可定义为透亮线的出现、放射学松动、临床松动，而翻修则为最终阶段。可区分出三类不同的影响参数：植入物相关、患者相关和外科医生相关。专家评论：本综述的目的是整理关于肩胛盂失败的现有知识，并描述其中的空白，以便为如何预防解剖型全肩关节置换术中肩胛盂失败的辩论做出建设性贡献。
