The aim of the study was to evaluate the 5- to 10-year results (mean, 6.2 years) of a modular uncemented revision stem (Profemur-R). From a total series of 184 consecutive stem revisions, the first 73 were evaluated. The implant was fixed without bone grafting in all cases. The average Harris hip score increased from 40 to 75. A complete remodeling of bone defects could be documented radiographically in 70% of the cases and a partial restoration in 30%. Progressive subsidence appeared in 2 stems. Three rerevisions were required, including 1 septic case. The survival rate with aseptic loosening as the end point was 96% over an average of 10 years. The revision prosthesis examined in this study can be considered a viable and useful option to reconstruct femoral defects in revision hip arthroplasty.
本研究的目的是评估模块化非骨水泥翻修柄（Profemur-R）5至10年的结果（平均6.2年）。在连续184例柄翻修病例中，对前73例进行了评估。所有病例均未植骨而将植入物固定。Harris髋关节平均评分从40分提高到75分。70%的病例在影像学上可记录到骨缺损完全重塑，30%为部分修复。2个柄出现渐进性下沉。需要进行3次再次翻修，其中1例为感染病例。以无菌性松动为终点的平均10年生存率为96%。本研究中检查的翻修假体可被视为翻修髋关节置换术中重建股骨缺损的一种可行且有用的选择。
