摘要
目的对全髋表面置换术治疗股骨头坏死的近期疗效作一小结,了解影响疗效的因素.方法自2000年10月～2004年12月,对15例18髋FicatⅢ、Ⅳ期股骨头坏死进行了全髋关节表面置换术,平均年龄39岁(23～49岁).手术方法按照Amstutz和Nelson提出的标准方法进行,术后进行定期随访.结果平均随访3.5年(6～50个月),无股骨颈骨折、无脱位、无感染.1例髋臼假体周围发现有透亮带,1例因股骨头假体位置不佳已行翻修.术前平均Harris评分30分,术后为90分,最近一次随访平均评分93分(89～98分).评价:优16髋,良1髋,差1髋.结论全髋关节表面置换术是治疗FicatⅢ、Ⅳ期且年龄较轻股骨头缺血性坏死的有效方法,近期随访结果满意.
Objective To evaluate the early results of total hip surface replacement for osteonecrosis, and review the factors affecting the results. Methods From Oct 2000 to Dec 2004, 18 hips of 15 patients at Ficat stage Ⅲ, Ⅳ osteonecrosis were treated with total hip surface replacement. Their average age was 39 years old （ranged 23- 49years old）. They all had the indications for hip surface replacement. The standard operation technique brought forth by Amstutz and Nelson was applied. The patients were followed up postoperatively. Results The average follow- up was 3.5years （6-50months）. No femoral neck fracture, dislocaton, or infection happened in all patients. Radiolucent line existed around acetabular prosthesis in 1 hip. One hip was revised because the prosthesis was not in correct situation. The average Harris hip score improved significantly from 30 to 90. The score in the latest follow- up was 93. According to Harris system, 16 hips were excellent, 1 hip was good, and 1 hip was fail. Conclusion Total hip surface replacement is an effective solution for the relative young patient at Ficat stage Ⅲ, Ⅳ osteonecrosis of femoral head. Although the short - term results are satisfactory, the long- term results need to be observed.
