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.

Arthroplasty Revision

Introduction: The increasing number of primary total hip replacements means that there is an increased need for hip arthroplasty revisions. The periprosthetic fractures which cause bone defects can occur during removal of the femoral component and healing of these fractures can be delayed. In femoral bone defects during revisions, there are no metal augments for filling these defects. Case Report: Fifty-nine-year-old female presented with infected loosening of the left hip non-cemented endoprosthesis 5 years after surgery. The patient underwent removal of endoprosthesis. In 2 months, re-implantation of non-cemented endoprosthesis was performed and biphasic calcium phosphate (BCP) ceramic granules with hydroxyapatite/?-tricalcium phosphate (HAp/?-TCP) were implanted in the femoral bone defects. Eleven months following the arthroplasty patient had periprosthetic fracture of the distal third of the left femur. The osteosynthesis was performed and BCP ceramic granules with HAp/?-TCP were used to fill the bone defect. Long-term follow-up showed very good functional outcome and bone defect healing. Conclusion: The BCP ceramic granules with HAp/?-TCP material adjusted to the bone defect anatomy, showed effective femoral bone defect and periprosthetic fracture healing in a patient with hip arthroplasty revision and periprosthetic fracture. Keywords: Bone defect, femoral, revision.

Revision Stem

Aseptic loosening in total hip arthroplasty can lead to proximal femoral periprosthetic bone loss. The non-cemented Wagner revision stem achieves primary fixation in the diaphysis. The purpose of this study is to evaluate the results after medium- to long-term follow-up of the Wagner prosthesis for revision of the femoral component for aseptic loosening in total hip arthroplasty with proximal femoral bone loss. We performed 53 femoral revisions for aseptic loosening with the non-cemented Wagner revision stem. Clinical assessment included a modified Harris Hip Score and a radiological evaluation. The mean follow-up was 65 months. The Harris Hip Score improved significantly (42.9 to 72.3). Radiological evaluation revealed 24.5% subsidence (>5 mm) in our population. Nine re-revisions were done, eight in the first post-operative year. The re-revisions were performed for progressive subsidence (five), recurrent dislocations (one), subsidence with low-grade infection (one), false route (one), and aseptic loosening after 75 months (one). The cumulative survival rate of the Wagner stem after 12 months was 85% and 76% after 75 months. A relatively high re-revision rate was observed during the first post-operative year. Analysis of these failures has shown that subsidence may be the result of insufficient primary stability. Adequate pre-operative planning and intra-operative radiological assistance is necessary for perfect primary stability and fixation of the Wagner stem. The re-revision incidence after the first 12 months is 0.45 per 100 implants per year. The prosthesis has good survival potential after proper introduction.
