摘要
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.
