潜行减压单侧改良TLIF手术治疗腰椎退行性疾患

Preliminary efficacy of decompressive unilateral improved transforaminal lumbar interbody fusion(TLIF) for the treatment of lumbar degenerative diseases

目的：观察椎管潜行减压单侧改良经椎间孔腰椎间融合术（transforaminal lumbar interbody fusion,TLIF）手术治疗腰椎退行性疾病的临床疗效。方法：自2009年8月至2011年12月,采用椎管潜行减压单侧改良TLIF手术治疗腰椎退行性疾病患者28例,其中男16例,女12例;年龄46-71岁,平均61岁;病程6个月-6年。腰椎管狭窄症20例,腰椎间盘突出症8例。潜行减压范围：单节段24例,双节段4例。左侧15例,右侧13例。采用JOA下腰痛评分系统（29分）评价手术前后临床症状、体征及括约肌功能;并采用视觉模拟评分（VAS）评估手术前后腰腿痛情况。结果：28例患者获随访,时间6-28个月,平均14个月。术后JOA、VAS评分（17.9±2.2、2.8±0.7）与术前（8.5±1.7、8.6±1.2）比较有明显改善（P〈0.05）。28例患者椎间均达到骨性融合。结论：采用椎管潜行减压单侧改良TLIF手术治疗单侧根性症状的腰椎管狭窄症、腰椎间盘突出症,具有创伤小、疗效确切的优点;能明显节省医疗费用,值得临床研究推广。

Objective：To observe preliminary efficacy of decompressive unilateral improved transforaminal lumbar inter- body fusion （TLIF） for the treatment of lumbar degenerative diseases. Methods：From August 2009 to December 2011, 28 patients with lumbar degenerative diseases were treated by decompressive unilateral improved TLIF,including 16 males and 12 females with an average of 61 （aged 46 to 71 ） years old, the courses of disease ranged from 6 months to 6 years. Among them, 20 cases suffered from lumbar spinal stenosis, 8 cases were lumbar disc herniation. Decompressive range included single segment in 24 cases,and double segments in 4 cases; 15 cases were performed operation on the left side, 13 cases on the right side. JOA lower back pain scoring system （29 points） were applied for evaluate preoperative and postoperative symptoms, physical signs and sphincteral functions;Visual analogue scale （VAS） were used to evaluate preoperative and postoperative low back pain. Resnits：All patients were followed up 6 to 28 （mean 14） months. Postoperative JOA score and VAS score were 17.9±2.2,2.8±0.7 respectively, and preoperative JOA score and VAS score were 8.5 ± 1.7,8.6± 1.2, respectively. There were significant meaning in JOA and VAS scores before and after operation （P〈0.05）. Twenty-eight patients were all obtained intervertebral synostosis. Conclusion ：Decompressive unilateral improved TLIF for treatment of unilateral radicular lumbar spinal stenosis and lumbar disc herniation,which has advantages of minimally invasive ,curative effects, decrease medical costs,is worthy spreading in clinical.
