游离型腰椎间盘脱出症44例临床分析

目的：探讨游离型腰椎间盘脱出症合并马尾神经损伤的发病率，分析临床症状，体征与影像学检查的重要意义。方法：４４例病人全部做ＣＴ扫描，诊断可疑者进行脊髓造影ＣＴＭ检查，脑脊液的检验，并且与马尾神经肿瘤进行了严格的鉴别。结果：马尾神经功能完全恢复３３例不，完全恢复１１例。恢复所需时间１．５－２年，唯双下肢瘫痪及性功能障碍恢复所需时间较长并且功能不理想。

Clinical Analysis of 44 Cases with Free Intervertebral Disc Cartilage Protruded into Spinal Canal

Aim:To estimate the incidence of free intervertebral disc cartilage protrusion complicated with cauda equina injury and analyse the importance of clinical symtom,physical sign and image examination.Methods:Computed tomography was performed on all of the 44 cases.For those with a doubtful diagnosis,computed tomographic myelography and cerebraspinal fluid testing were taken,Strict differential diagnosis was made to exclude tumor of cauda equina.Results:Full recovery for the function of cauda equina was obtained in 33 cases,partial recovery in 11 cases .The recovery time ranged from 1.5 years to 2years.Time for recovery of paralysed lower extrimity and sexual disorder was relatively longer with poor result.Conclusion:The effect of operation depends on severity of original injury.For those patients with a large piece of cartilage protruded into subarachnoid cavity,the prognosis was poor.Correct diagnosis and timely operation are very important if a good prognosis is expected.
