Numbers of total hip replacements are steadily increasing. The most common complication of hip replacement is late implant loosening, which can be predicted by early migration. We will examine early migration of a trabecular metal acetabular cup without screws, compared to a titanium fibre metal acetabular cup fixed with screws. Ideally, an acetabular cup would achieve a level of initial stability by press-fit alone without screws, as screws increase the risk of bone loss around the prosthesis.

全髋关节置换术的数量正在稳步增加。髋关节置换术最常见的并发症是晚期植入物松动，这可以通过早期移位来预测。我们将研究骨小梁金属髋臼杯（无螺钉）与钛纤维金属髋臼杯（螺钉固定）的早期移位。理想情况下，髋臼杯仅通过压配而无需螺钉即可实现一定程度的初始稳定性，因为螺钉会增加假体周围骨丢失的风险。
