Stemless hip prosthesis replacement in the treatment of middle and young-aged patients with femoral head necrosis:the short-term curative effects analysis

目的探讨无柄髋关节置换治疗中青年股骨头坏死患者的中近期疗效。方法对19例中青年股骨头坏死患者19髋采用无柄髋关节置换术，对其临床效果进行评述分析。结果19例患者疗效满意，术后随访6-65个月，按Harris评分为平均（89．4±6．5）分。优13例，良5例，中1例。优良率为94．7％。结论无柄髋关节置换术，适用于中青年股骨头缺血性坏死晚期患者，中近期疗效好，能有效保存骨量，但远期效果有待长时间观察。

Objective To explore the short-term effects of the stemless hip prosthesis replacement on treating middle and young-aged patients with femoral head necrosis. Methods 19 cases （middle or young-aged） suffered from femoral head necrosis received the stemless hip replacement surgery, and followed by the evaluation of clinical effects. Results The follow up time was about 6 to 65 months. All patients recovered, with the Harris score of 89.4± 6.5 points averagely （ excellent in 13 cases, good in 5 cases, medium in 1 case）.
