MED技术治疗腰椎间盘突出症相关因素分析(附220例报道)

The Analysis of Related Factors on Microendoscopic Discectomy for Treatment of Lumbar Disc Herniation(reports of 220 cases)

目的：探讨显微内镜腰椎间盘髓核摘除术（MED）的相关因素,评价MED的临床价值。方法：对220例腰椎间盘突出症手术患者进行回顾性分析。其中男124例,女96例;平均年龄37.6岁（26-63岁）;病变节段：L4、5109例,L5S1103例,L4、5L5S18例。采用旁正中小切口,在内镜下完成神经根探查、减压和椎间盘髓核摘除。结果：平均随访14.5个月,用改良MacNab标准评定随访结果：优176例,良37例,可7例。结论：MED表现有较好临床效果,具有切口小、组织损伤轻和恢复较快的特点。

Objective：To explore the clinical effect of microendoscopic discectomy（MED） in the treatment of lumbar disc herniation（LDH）.Methods：A total of 220 cases with LDH were studied in the present study,124 males and 96 females with an average age of 37.6 years（ranged 26~63）.Herniated disk occurred at L4,5 in 113 cases and at L5,S1 in 107 cases.MED was performed via a small paracentral approach that allowed thorough root exploration,direct decompression and removal of disc material.Results：The groups were followed up for 14.5 months,averagely.Excellent effect was observed in 176 cases,good effect in 37 cases and fair effect in 7 cases based on modified MacNab criteria.Conclusion：MED offers a better clinical outcome,with smaller incision,less tissue trauma and quicker recovery.
