【摘要】 为预防和治疗小儿先天性髋脱位术后再脱位。对１９７２年末～１９９５年３月间５５例（５８髋）小儿先天性髋脱位术后再脱位的病例进行随访，随访时间最长１４年，最短１．５年，平均６．９年。结果发现２例（４髋）为双侧再脱位，１例为单侧３次脱位，余均为单侧再脱位。其中半脱位１４例（１６髋），占２７．６％，全脱位４１例（４２髋），占７２．４％。再脱位的发生率３．７５％。术式选择不当、手术操作不妥、术后处理失误及功能练习错误是引起该病的常见原因，也是要我们预防该病发生的关键环节。一经发现再脱位，应及早处理，方法要确切、简单、实用更多还原

【Abstract】 In order to prevent and treat the redislocation after operation of congenital dislocation of hip in children, 55 cases (58 hips) treated from the end of 1972 to March 1995 were followed up. The followingup time varies from 14 years to 1.5 years, averaging 6.9 years. Two cases (4 hips) were bilateral redislocation, one case was unilateral three times dislocation, others were unilateral redislocation. Among them, the subluxation were 14 cases (16 hips 27.6%) the complete dislocation were 41 cases (42 hips 72.4%). Incidence of the redislocation was 3.75%. The unsuitable selection of operation methods, incorrect performance of operation, errors of treatment after operation and errors of function exercise are the common reasons that arising the redislocation and they are also the key links we prevent it. Once discovering it, we should treat it as early as possible and treatment methods should be exact, simple and practical.更多还原
