Fluted tapered revision femoral stems have been used successfully in Europe. Modularity makes these implants more versatile, but outcomes of modular designs have not been reported. We report a retrospective review of 70 such stems with a mean follow-up of 47 months. Combined metaphyseal/diaphyseal bone loss was present preoperatively in 36 (51%) of 70 hips. Three hips (4.3%) were re-revised or in need of re-revision, and worst-case survival was 87%. The mean postoperative patient-assessed Oxford Hip Score was 21.1. Restoration of proximal bone was noted in 56%. Complications included mean subsidence of 9.9 mm, dislocation in 7 (10%) of 70 hips, and fracture or cortical perforation in 17 (24.2%) of 70. These results are equivalent to, or better than, reported results of other types of cementless revision femoral stems.
带槽锥形翻修股骨干假体已在欧洲成功应用。模块化设计使这些植入物更具通用性，但模块化设计的结果尚未见报道。我们对70例此类假体进行了回顾性研究，平均随访47个月。70例髋关节中，36例（51%）术前存在干骺端/骨干联合骨质流失。3例髋关节（4.3%）进行了再次翻修或需要再次翻修，最差情况下的生存率为87%。术后患者评估的牛津髋关节评分平均为21.1分。56%的患者近端骨质得到恢复。并发症包括平均下沉9.9毫米，70例髋关节中有7例（10%）发生脱位，70例中有17例（24.2%）发生骨折或皮质穿孔。这些结果与其他类型的非骨水泥翻修股骨干假体的报道结果相当或更好。
