We treated 45 hips with idiopathic necrosis of the femoral head stages I-III with core decompression. Average age of patients was 41 (27-68) years and average follow-up 68.9 (31-120) months. In 30 hip joints in stage I, 29 showed no radiographic progression and a complete remission of the changes consistent with necrosis on MRI at the last follow-up. In 27 patients the clinical result based on the Harris Hip Score (HHS) assessment--was excellent (average HHS 91.9 points). Of nine hips in stage II, four had received a total hip arthroplasty, one had deteriorated to stage IV, and four were still classified as stage II (average HHS 95 points). Of six hips in stage III, three had received a total hip arthroplasty and three had deteriorated to stage IV (average HHS 73 points).
我们采用髓芯减压术治疗了45例I - III期股骨头缺血性坏死的髋关节。患者平均年龄为41（27 - 68）岁，平均随访时间为68.9（31 - 120）个月。在30个I期髋关节中，29个在最后一次随访时未出现影像学进展，且MRI上与坏死相符的改变完全缓解。基于Harris髋关节评分（HHS）评估，27例患者的临床结果为优（平均HHS 91.9分）。在9个II期髋关节中，4个接受了全髋关节置换术，1个恶化为IV期，4个仍归类为II期（平均HHS 95分）。在6个III期髋关节中，3个接受了全髋关节置换术，3个恶化为IV期（平均HHS 73分）。
