【摘要】 【目的】初步评定脑瘫髋发育畸形,并探讨选择性脊神经后根切断术(SPR)对脑瘫髋关节的影响。【方法】收集自1992年10月至2000年12月SPR手术治疗的脑瘫患者共195例,男142例,女53例,年龄3～22岁,平均6.9岁。其中29例患者术前测量髋关节的Sharp角和头骺外移百分比。【结果】术前行X片检查而证实有髋关节半脱位或脱位者6例;术后复诊的61例中,又出现患者髋半脱位或脱位有3例,分别为术后1年、7年及7年时出现。术前髋关节的Sharp角的异常百分比为29.8%;头骺外移百分比(MP)大于33%有3例。【结论】脑瘫存在髋关节发育不良,可表现为Sharp角和MP值的增大;部分患者存在髋关节的半脱位或脱位。SPR术后髋关节半脱位或脱位的可能性仍存在,需要临床早期发现和治疗。更多还原

【Abstract】 To access hip deformity of cerebral palsy and observe the effect of selective posterior rhizotomy(SPR) on hip joint of cerebral palsy. From October ,1992 to December,2000,195 patients received selective posterior rhizotomy(SPR) in our department, among them 142 were boys and 53 girls, with an average age of 6.9 years. Fifty seven Sharp angle of hip joints of 29 cases who suffered cerebral palsy were statisticed, the average angle of them (46.74±5.62)°ranged from 38°to 58°. Among them, 17 sharp angles were over 50°, the abnormal ratio of which was 29.8%. Migration percentage (MP) ranged from 0 to 50%. That of average angle was (22±8)%. 3 cases was over 33%. But they were not diagnosed as hip subluxation. There were 6 cases of hip subluxation or dislocation checked by radiography before operation and 3 cases of hip subluxation after operation. [Conclusion]There were hip dysphasia among cerebral palsy, the angle of sharp and values of MP might accreted. Some patients might have hip subluxation or dislocation appeared after operation. It was necessary to discover earlier and treat them in time.更多还原
