Abstract

Simultaneous bilateral total hip arthroplasty (THA) is an increasingly common procedure. Although use of a cementless stem can eliminate cement complications, some surgeons limit application of cementless THA because of concerns about early implant loosening. In this article, we report on 30 cementless THA cases (15 patients) followed up for a minimum of 2 years (range, 26-50 months). Despite 73% of femoral bone being type B or type C, all stems showed stable bone ingrowth fixation and no evidence of subsidence. Polyethylene wear rates (left, 0.154 mm/y; right, 0.114 mm/y) did not differ significantly. The excellent clinical results obtained with simultaneous bilateral cementless THA are comparable with those obtained with unilateral THA.

摘要

同期双侧全髋关节置换术（THA）是一种越来越常见的手术。尽管使用非骨水泥型股骨柄可以消除骨水泥相关并发症，但一些外科医生由于担心早期植入物松动而限制非骨水泥型THA的应用。在本文中，我们报告了30例非骨水泥型THA病例（15例患者），随访时间至少为2年（范围为26 - 50个月）。尽管73%的股骨骨为B型或C型，但所有股骨柄均显示出稳定的骨长入固定，且无下沉迹象。聚乙烯磨损率（左侧，0.154 mm/年；右侧，0.114 mm/年）无显著差异。同期双侧非骨水泥型THA所获得的优异临床结果与单侧THA相当。
