OBJECTIVE: To evaluate 49 hips in 48 patients submitted to revision total hip arthroplasty using Wagner stem. METHODS: From April 1999 to January 2005, 49 hips were treated in patients with femoral loosening (39 hips) or periprosthetic fracture of the femur (10 hips) with revision arthroplasty using the Wagner prosthesis. Mean follow-up lasted 35 months and mean age was 63.4 years. Revisions of the femoral component were performed in 49 hips, with concomitant acetabular component revision in 36 hips. RESULTS: Results evaluation according to the D'Aubignè-Postel-Charnley index presented a statistically significant improvement in the post-operative period in comparison to the pre-operative period (p < 0.001). The most important problems seen were the high rate of dislocations (three hips) and dislocations associated to the deepening of the stem (two hips). The four unsatisfactory results were due to loosening (two hips), infection (one hip), and acetabular loosening (one hip). All of the unsatisfactory results occurred in the group of aseptic loosening, but this finding was not statistically significant (p = 0.569). Restoration of bone stock (radiographic evaluation) was seen consistently in most cases, without correlation with patient age (p = 0.852). Likewise, clinical results were not related to patient ages (p = 0.636). CONCLUSION: The procedure of femoral revision with Wagner prosthesis yields clinical and radiographic satisfactory results and consistently restores femoral bone stock.
