The use of a modular metaphyseal-diaphyseal femoral stem in primary total hip arthroplasty is infrequent. We analyze 94 ESOP (Fournitures Hospitalieres, Heimsbrunn, France) cementless 2-piece modular stems after a minimum 5 years of follow-up. There were 2 aseptic femoral stem loosenings and no cases with thigh pain. Mean femoral canal filling was 90%. Radiographic ingrowth was obtained in 83 (P < .001). At 7 years, the survival rate for femoral aseptic loosening was 97.8% and no stem was at risk for revision (95% confidence interval, 94.8%-100%). This prosthesis provides good clinical results with absence of pain and excellent radiographic results. It is an option in femora with good bone quality. Femoral osteopenia and cortical widening were infrequent, and the modular metaphyseal-diaphyseal junction was not a problem in vivo.
在初次全髋关节置换术中，使用模块化股骨干骺端-骨干型股骨柄的情况并不常见。我们对94例采用ESOP（法国海姆斯布伦的Fournitures Hospitalieres公司生产）非骨水泥型两件式模块化股骨柄的患者进行了分析，随访时间最短为5年。有2例无菌性股骨柄松动，无大腿疼痛病例。平均股骨髓腔填充率为90%。83例获得影像学骨长入（P <.001）。在7年时，股骨无菌性松动的生存率为97.8%，没有股骨柄面临翻修风险（95%置信区间，94.8%-100%）。这种假体提供了良好的临床效果，无疼痛，影像学结果优异。对于骨质良好的股骨，它是一种选择。股骨骨质减少和皮质增宽并不常见，并且模块化干骺端-骨干交界处在体内不是问题。
