切吸治疗腰_5～骶_1椎间盘突出症方法的改进

Improve Operating Methods of APLD for the Ls～Sl Lumbar Disc Herniation

目的：提高腰5～骶1：椎间盘突出症（Ls～S1Lumbar Disc Herniation；简称Ls～S１LDH）穿刺成功率及切吸的疗效。方法：分两组统计分析。前组：1994年至1997年4月间，收治疗25例L5～S1LDH，采用当时通用的方法穿刺切吸；后组：1997年5月至1999年12月间，收治31例L5～S1LDH，应用改进的方法穿刺切吸。结果：穿刺的成功率，前组64．0％，后组87．1％。经卡方检验（x2=4．14），P＜0．05，表明两组穿刺成功率的差异有显著性。经随访，前组优良率43．8％，后组为74．1％。经卡方检验（x2＝3．95），p＜0．05，两组疗效优良率的差异有显著性。结论：改进的 L5～S1LDH穿刺与切吸的方法是一种有效的微创手术。

Abstract:Obsjective: To raise the clinical effect of the active percutaneous lumbar disc(APLD) for the L5～S1lumbosacral disc herniaton(LDH). Methods:56 cases of L5～S1 LDH were treated with the general way(a front group),or an improve methods(a find group) of APLD, which were in 25 cases and 31 cases respectivey. between September1994 and December 1999. It was accomplished with a research into the improve improve of APLD. Results: A successrate of the percutaneous. Which were 64. 0% and 87. 1% respectively(P< 0. 05) in the front and the find groups for L5～S1 LDH. On a clinical effect of APLD for two groups. that it was evaluated as excellent and good rate, it was 43. 8%and 74. 1% respectively(P< 0. 05 ), according to the criteria of lumbar function evaluation set up by Macnab. Conclusion:The improve methods of APLD was more effective approach to L5～S1 LDH.
