- Abstract
Purpose: The purpose of this study was to assess the clinical and radiographic results of a total hip arthroplasty with the double tapered Mallory-Head system. Methods: The clinical and radiographic results of a consecutive series of 81 total hip replacements in 75 patients were reviewed 10-15 years (average 11.4 years) postoperatively. The patients' underlying conditions were avascular necrosis in 46 hips (57 %), osteoarthritis in 12 hips (15 %), RA in nine hips (11 %), and others. Clinical results were evaluated based on the modified Harris hip score and modified Merle d'Aubigné-Postel score. A radiographic analysis was performed. Results: The average modified Harris hip score improved from a preoperative score of 56 points to a postoperative 92 points. The average modified Merle d'Aubigné-Postel score was 15 points at the latest follow up, and 55 hips (68 %) were classified as the clinical grades of excellent or good results. One acetabular component was revised because of loosening, and one was revised for recurrent dislocation. Conclusion: The clinical and radiological evaluations of the total hip replacements using the Mallory-Head system showed good results.
