The risks and benefits of contemporary total hip replacement

澳大利亚的髋关节置换手术数量正在稳步增加。髋关节置换最常见的并发症是假体周围骨丢失导致的脱位和松动，需要复杂而昂贵的翻修手术。这项研究将调查脱位的发生率，并使用一种新的诊断成像技术，研究一种相对较新的假体材料周围骨丢失的发生率和数量，尽管这种假体材料的使用越来越多，但其结果尚不清楚。

The number of hip replacements undertaken in Australia is steadily increasing. The most common complications of hip replacements are dislocation and loosening due to bone loss around the implant, requiring complex and expensive revision surgery. This study will investigate the incidence of dislocation and, using a new diagnostic imaging technique, the incidence and amount of bone loss around a relatively new prosthetic material, the outcomes of which are not known despite its increasing use.
