Abstract

Experience in revision hip arthroplasty with change of femoral stem was analyzed for 165 patients. In 107 operations (64.8%) Wagner SL Revision Stems were used, in the rest of cases - femoral components of other manufacturers. Distribution of patients by femoral defect type by Paprovsky was the following: I type - 27 patients, II type - 75, IIIA type - 59, IIIB and IV type - 4 patients. Good results at use of Wagner SL Revision Stems and stems of other manufacturers were comparable and made up 87.9 and 86.2%, respectively. Achieved data enabled to make conclusion that Wagner SL Revision Stem use is reasonable for patients with hip implant instability in I-IIIA femoral bone deficit, as they are cheaper than the modular revision stems and their design prevents the wear in the area of modular junction.
