Abstract

Modular bipolar prostheses were developed to address the problems of loosening, cartilage wear, and protrusio which were seen with single unit endoprostheses. Modular unipolar prostheses address many of these problems and are significantly less expensive than the bipolar prosthesis. Recent data suggest that use of the modular unipolar prosthesis is indicated in elderly patients with low demands.

摘要

模块化双极假体的研发是为了解决单部件内置假体所出现的松动、软骨磨损和髋臼前突等问题。模块化单极假体解决了其中许多问题，且比双极假体便宜得多。近期数据表明，对于需求较低的老年患者，建议使用模块化单极假体。
