We retrospectively reviewed 123 patients who underwent cementless THA with modular femoral stem designs for revision THA or conversion of failed ORIF and found 75 patients available for analysis. The Harris Hip Score (HHS) improved from 52 ± 14 to 86 ± 11 (P < 0.001). The femoral stem was re-revised in eight patients (11%). The mean time to re-revision was 1.1years (0.13-2.54). Reasons for re-revision included infection (n = 5, 7%), aseptic loosening (n = 2, 3%) and significant pain (n = 1, 1%). There were no failures of the modular junctions. PC stems had an increased rate of intraoperative fractures (PC 28% vs. STS 9%, P = 0.04). Modular cementless femoral stems provide acceptable mid-term results in revision THA.
我们回顾性分析了123例行非骨水泥型全髋关节置换术（THA）的患者，这些患者采用模块化股骨柄设计用于翻修THA或失败的切开复位内固定术（ORIF）的转换，发现75例患者可供分析。Harris髋关节评分（HHS）从52±14提高到86±11（P<0.001）。8例患者（11%）进行了股骨柄再次翻修。再次翻修的平均时间为1.1年（0.13 - 2.54年）。再次翻修的原因包括感染（n = 5，7%）、无菌性松动（n = 2，3%）和严重疼痛（n = 1，1%）。模块化连接部位无失败病例。PC柄的术中骨折发生率较高（PC 28% vs. STS 9%，P = 0.04）。模块化非骨水泥型股骨柄在翻修THA中提供了可接受的中期结果。
