We reviewed at a minimum elapsed time of five years a consecutive series of 143 primary Exeter hip replacements in which matt-surfaced femoral stems had been used. Twenty-five patients had died and six stems and two sockets had been revised before follow-up. The remaining 110 hips were all examined clinically and radiographically. In 15 hips there were radiographic signs of definite loosening of the stem and in eight suspected loosening. The acetabulum was loose in four hips. In another eight hips localised bone resorption was present without signs of loosening. Half the patients with loosening or localised bone resorption had mild pain or no pain at all. The late complication rate with the matt-surfaced Exeter femoral stem is unacceptably high.
我们回顾了连续143例使用磨砂表面股骨柄的埃克塞特原发性髋关节置换术，最短随访时间为5年。25例患者已死亡，6个股骨柄和2个髋臼杯在随访前已翻修。其余110例髋关节均进行了临床和影像学检查。15例髋关节有股骨柄明确松动的影像学表现，8例疑似松动。4例髋关节髋臼松动。另外8例髋关节存在局限性骨吸收但无松动迹象。半数有松动或局限性骨吸收的患者有轻度疼痛或根本没有疼痛。磨砂表面的埃克塞特股骨柄的晚期并发症发生率高得令人无法接受。
