生物型加长柄全髋置换治疗老年不稳定性股骨转子间骨折

背景：老年股骨转子间不稳定性骨折内固定后愈合较差,普通髋关节置换固定不稳,有待新的治疗手段解决这一难题。目的：回顾性分析生物型加长柄人工髋关节置换治疗老年股骨转子间不稳定性骨折的疗效。方法：2004-01/2011-09采用生物型加长柄人工髋关节置换治疗老年股骨转子间不稳定性骨折26例。人工髋关节为捷迈公司生物性加长柄人工髋关节,生物相容性良好。结果与结论：随访时间2年~5年6个月,置换后疗效均满意,患者置换后可早期下地活动,髋关节无疼痛,关节功能良好,生活质量明显改善。随访至置换后2年的24例行Harris髋关节评分,优9例,良11例,可3例,差1例,优良率为83%,其中1例出现人工关节下沉。提示生物型加长柄人工髋关节置换治疗老年股骨转子间不稳定性骨折可明显缩短患者置换后卧床时间,有利于早期恢复功能锻炼,效果显著,是一种相对安全有效的治疗方法。

Cementless lengthened-handled hip joint replacement for the treatment of unstable intertrochanteric fractures in elderly people

BACKGROUND:The healing of unstable intertrochanteric fractures in elderly people is poor after internal fixation, and fixation with ordinary hip replacement is unstable, so a new therapeutic means is needed to solve this problem.OBJECTIVE:To study the curative effect of cementless lengthened-handled hip joint replacement on the treatment of unstable intertrochanteric fractures in elderly people.METHODS:From January 2004 to September 2011, 26 cases of unstable intertrochanteric fractures in the hospital were cured with cementless lengthened-handled hip joint replacement. The artificial hip joint was the lengthened-handled hip joint from Zimmer with a good biocompatibility.RESULTS AND CONCLUSION:All patients were followed-up for 2 to 5 years and 6 months. The results of this surgical method were satisfied, all patients could walk early without hip pain, and the joint function was good. Life quality of these patients was improved obviously. The Harris score of the hip joint of these 24 cases after two years follow-up revealed that 9 cases had excellent therapeutic result, 11 cases were fine, 3 cases were ordinary, and 1 case was bad. The excellent and good rate was 83%. One case appeared artificial joint dislocation sinking. This method of cementless lengthened-handled hip joint replacement for the treatment of unstable intertrochanteric fractures had got satisfied results. Patients treated with this surgery could walk early and conducive to the early recovery exercise. So it is a relatively safe and effective treatment method for treating unstable intertrochanteric fractures in elderly.
