Abstract
- PURPOSE
To analyze the results of a 5-12 year (mean, 7 years, 5 months) follow-up of femoral revision THA using the Wagner(R) stem.
MATERIALS AND METHODS
Of 79 revision THA patients enrolled in the study between March 1991 and January 2000, there were 64 cases of aseptic loosening (69 hips, 44 males and 20 females) during a minimum 5-year follow-up. In addition, postoperative complications and clinical and radiographic results were evaluated.
RESULTS
The Harris hip score improved from 48.6 to 91.2 points, postoperatively. There were 3 revisions due to failed stem fixation and aseptic loosening. The Kaplan-Meier survivorship analysis, with failure defined as a removal of the Wagner(R) stem, revealed a 97.1% survival at a 12-year follow-up. Besides the revisions, there were 66 hips that were hip-related symptom-free. However, there was claudication in 1 case. Radiographic findings included subsidence of the implant (5 cases, 7.5%, all less than 10 mm), calcar femorale atrophy (4 cases, 6.0%), stress shielding (4 cases, 6.0%), and heterotopic ossification (5 cases, 7.5%). Postoperative peroneal nerve palsy (2 cases) resolved completely within the following 6 months.
CONCLUSION
We obtained a stable fixation and satisfactory results in the cases we studied using the Wagner(R) revision stem.
