摘要 目的:探讨同期双侧钽棒植入治疗成人双侧早期股骨头坏死的疗效。方法:入组11例双侧早期股骨头坏死患者同期行双侧钽棒植入治疗,在C臂X线机定位下植入合适长度钽棒,术后髋关节X片、MRI观察股骨头变化,同时行髋关节harris评分。结果:全部患者均随访18~24个月,平均22个月。1例1髋术后18个月,MRI提示从SteinbergⅢa期进展为SteinbergⅢb期,其余未发现股骨头塌陷和坏死加重;术前Harris评分(74±12.72),术后6月为(93.77±4.67),术前术后对比有统计学差异(P〈0.05)。结论:同期双侧钽棒植入治疗成人双侧早期股骨头坏死安全、有效,同样能有效延缓股骨头塌陷,近期随访疗效满意。 Objective:Studying the clinical effects of simultaneously bilateral tantalum rod implantationtreatment of adult osteonecrosis of the femoral head(ONFH).MethodsEleven patients(22 hips) sufferingfrom early stage of bi-ONFH were chosen. X-ray film, CT scan and MRI were taken pro-operatively, simultane-ously bilateral tantalum rod implantation treatment was carried out. Appropriate size of the tantalum rod was im-planted with the C-arm X-ray machine. Those patients were followed up regularly after the operation observingthose changes in hip bone via X-ray film, MRI check and assessed by Harris Scale.ResultsAll cases werefollowed up after 22 months(18~24 months),Only one patient(1 hip) developed from Steinberg Ⅲ a into Stein-berg Ⅲ b according to MRI taken 18 months later. No aggravation in hip bone collapse or necrosis was foundamong other patients. Harris Scale scores for pre-operative and post-operative follow up visits showed pain, func-tion, mobility scores and total score(pre-operative:74.59±12.72 to post-operative:93.77±4.67),all presentingstatistical differences(P 0.05).ConclusionSimultaneously bilateral tantalum rod implantation treatment ofadult osteonecrosis of the femoral head is safe and effective. It can effectively avoid hip bone collapse among ne-crosis area and proves satisfactory curative effect according to recent follow up visits.
