The aim of the study was to evaluate the results of total hip arthroplasty (THA) due to avascular necrosis (AVN) of the femoral head and to establish whether the cause of AVN affects the results.
A group of 68 patients, 17-82 years of age (mean: 49.9 years) underwent 84 total hip arthroplasties due to AVN. The patients were divided into subgroups according to the etiology of AVN of the hip joint. The results of each group were evaluated by the Harris Hip score (HHS) at 3-18 years (mean: 6.2 years). The complication rate was also assessed.
The mean preoperative HHS was 28.5+/-4.5 as opposed to a postoperative HHS of 86+/-10. The revision rate was 16.7%. Etiology does not affect the final outcome, but less favorable long-term results were found in the steroid-induced AVN patients.
Despite the previously reported, less favorable results, THA is a good option for the younger population, even with AVN, especially in bilateral disease. Etiology did not affect the final outcome. However, patients with steroid-induced AVN should be informed that although their final functional results will equal those of other groups, the longevity of the implants is limited.
本研究的目的是评估因股骨头缺血性坏死（AVN）行全髋关节置换术（THA）的结果，并确定AVN的病因是否会影响结果。
一组年龄在17 - 82岁（平均49.9岁）的68例患者因AVN接受了84次全髋关节置换术。根据髋关节AVN的病因将患者分为亚组。每组结果在3 - 18年（平均6.2年）时通过Harris髋关节评分（HHS）进行评估。同时评估并发症发生率。
术前平均HHS为28.5±4.5，术后HHS为86±10。翻修率为16.7%。病因不影响最终结果，但在类固醇诱导的AVN患者中发现长期结果较差。
尽管先前报道结果较差，但THA对于年轻人群是一个不错的选择，即使是患有AVN的患者，尤其是双侧患病者。病因不影响最终结果。然而，应告知类固醇诱导的AVN患者，尽管他们的最终功能结果将与其他组相同，但植入物的使用寿命有限。
