目的 评价同种异体骨在人工髋关节翻修术中的应用价值 ,以及了解术前服药对人工关节翻修术的影响。方法 回顾性分析 2 5例全髋关节翻修术病例 ,所有病例术中均使用同种异体骨植骨 ,并按照术前有无特殊用药史 ,分为 3组 :A组为无特殊用药组、B组为消炎镇痛药组、C组为糖皮质激素组。比较各组术后一般情况、Harris功能评分。结果 A、B组患者术后一般情况良好 ,C组术后部分患者出现持续伤口渗液 ;Harris关节功能评分比较 :A、B两组优于C组。结论 同种异体骨能有效修复髋臼侧骨缺损 ,人工关节松动引起疼痛的患者应避免使用糖皮质激素。

Objective To evaluate the application value of bone allograft in the revision total hip arthroplasty and investigate the influence of preoperative medicine therapy on the outcome of the revision total hip arthroplasty. Methods 25 cases with bone allograft were analyzed retrospectively. According to the preoperative medicine therapy, all cases were divided into 3 goups: Group A without medicine administration, Group B with anti-inflammatory analgesics and Group C with glucocorticoid hormone. The general conditions and Harris hip scores were compared. Results The general conditions in Group A and B were good. Persistent incision drainage occurred in parts of Group C. Harris hip scores in Group A and B were better than that in Group C. Conclusion Bone allograft can be used to repair the acetabular defects effectively. Glucocorticoid hormone should be avoided for those suffer from pain due to joint prothesis looseness.
