Abstract:
PURPOSE: The purpose of this study was to assess the clinical and radiographic results of total hip arthroplasty with using the double tapered Mallory-Head system. MATERIALS AND METHODS: The clinical and radiographic results of a consecutive series of 81 total hip replacements in 75 patients were reviewed at eight to twelve years (average: 9.8 years) postoperatively. The underlying diseases were avascular necrosis in 46 hips (57%), osteoarthritis in 12 hips (15%), RA in 9 hips (11%) and others. The clinical result was evaluated on the basis of the modified Harris hip score and the modified Merle d'Aubigne-Postel score. A radiographic analysis was also performed. RESULTS: The average modified Harris hip score was improved from preoperative 56 points to postoperative 92 points. The average modified Merle d'Aubigne-Postel score was 15 points at the latest follow up, and 55 hips (68%) were classified as having clinical grades of excellent or good results. One acetabular component was revised because of loosening, and one was revised because of recurrent dislocation. CONCLUSION: The clinical and radiological evaluations of the total hip replacements using the Mallory-Head system showed good results.
