Abstract：
In this era of subspecialty care in orthopedics, iterations of implant design can occur in a silo which then precludes gaining knowledge from failures of implant design that may have occurred in different subspecialties. This literature review describes the history of failures in hip and shoulder arthroplasties with the purpose of identifying similar factors that led to previous implant failures. A review of the literature was performed by two reviewers assessing articles that described failed hip and shoulder arthroplasty systems over time. We identified and analyzed 53 implant failures-23 in hip arthroplasty and 30 in shoulder arthroplasty. These failures were categorized as material, mechanical, and technical. In hip arthroplasty, 48% were material, 39% mechanical, and 13% technical failures. In shoulder arthroplasty, the distribution was 10% material, 70% mechanical, and 20% technical failures. The distribution of these failures highlights similar and sometimes repeated failure mechanisms between subspecialties. This accentuates the importance of a collaborative approach to improve future arthroplasty designs.
摘要：
在这个骨科亚专科护理的时代,植入物设计的迭代可能发生在筒仓中，然后从可能发生在不同亚专业中的植入物设计失败中排除了知识。这篇文献综述描述了髋关节和肩关节置换术失败的历史，目的是确定导致先前植入物失败的类似因素。两名审阅者对文献进行了回顾，评估了描述随着时间的推移髋关节和肩关节成形术系统失败的文章。我们确定并分析了53例植入物失败-髋关节置换术中的23例和肩关节置换术中的30例。这些故障被归类为材料，机械,和技术。在髋关节置换术中,48%是材料，39%机械,13%的技术故障。在肩关节成形术中,分布是10%的材料，70%机械,20%的技术故障。这些故障的分布突出了亚专业之间相似且有时重复的故障机制。这强调了协作方法改善未来关节成形术设计的重要性。
