One conclusion that might be drawn from a review of the role of biomaterial failure in total hip arthroplasty is that the fracture, wear, and corrosion of materials often serve as the primary causes of failure of hip replacements. It is not yet possible, however, to conclude the prevalence or time course of these failures. We need to gain more knowledge about the properties of orthopedic biomaterials and the loading to which they are subjected during function. Judicious design and implementation of prostheses can serve to extend the serviceable life of an arthroplasty even with ongoing fracture, wear, and corrosion of biomaterials.
对生物材料失效在全髋关节置换术中作用的回顾可能得出的一个结论是，材料的断裂、磨损和腐蚀常常是髋关节置换失败的主要原因。然而，目前尚无法确定这些失效的发生率或时间进程。我们需要更多地了解骨科生物材料的特性以及它们在功能过程中所承受的负荷。即使生物材料持续出现断裂、磨损和腐蚀，明智地设计和应用假体也有助于延长关节置换术的使用寿命。
