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.
目的
本研究旨在评估使用双锥形马洛伊-海德系统的全髋关节置换术的临床和影像学结果。
方法
对 75 例 81 例全髋关节置换术后 10-15 年（平均 11.4 年）的连续系列病例的临床和影像学结果进行回顾性分析。患者的基础疾病包括 46 髋（57%）的缺血性坏死、12 髋（15%）的骨关节炎、9 髋（11%）的类风湿关节炎和其他疾病。临床结果基于改良 Harris 髋关节评分和改良 Merle d'Aubigné-Postel 评分进行评估。进行了影像学分析。
结果
平均改良 Harris 髋关节评分从术前的 56 分提高到术后的 92 分。末次随访时平均改良 Merle d'Aubigné-Postel 评分为 15 分，55 髋（68%）的临床分级为优秀或良好。1 个髋臼组件因松动而翻修，1 个因复发性脱位而翻修。
结论
使用马洛伊-海德系统的全髋关节置换术的临床和影像学评估显示出良好的效果。
