两种手术体位下治疗腰椎间盘突出症的疗效比较

  目的  比较两种不同体位下行开放性手术治疗腰椎间盘突出症的临床疗效，探讨简易跪式手术床在跪式体位下行椎板开窗减压髓核摘除术的临床优势。  方法  选取2019年12月~2020年12月于河西学院附属张掖人民医院骨科收治的132例单节段单侧腰椎间盘突出症患者，行单侧椎板开窗减压髓核摘除术治疗。采用随机数字表法将患者进行分组，就采用简易跪式手术床在跪式体位下手术治疗的患者（观察组，n=67）和采用常规手术床在俯卧位下手术治疗的患者（对照组，n=65）手术效果展开对比。比较两组患者的手术时间、术中出血量、术后卧床时间、术后住院时间及并发症发生情况的差异；比较两组患者术前、术后1周及1、3、6月的Oswestry功能障碍指数、疼痛视觉模拟评分及两组患者术后6月的临床疗效（MacNab优良率）。  结果  观察组的手术时间、术中出血量、卧床时间、住院时间及并发症例数均小于对照组（P < 0.05）；与术前相比，两组患者术后1周及1、3、6月的Oswestry功能障碍指数和视觉模拟评分均明显低于术前（P < 0.05）；与对照组相比，术后1周及1、3、6月，观察组患者的Oswestry功能障碍指数和视觉模拟评分均低于对照组（P < 0.05）；术后随访6月，观察组患者手术治疗后的临床疗效优于对照组（MacNab优良率91.04% vs 84.62%，P < 0.05）。  结论  两种术式均可行椎板单侧开窗减压髓核摘除，消除神经症状。跪式体位下行椎板单侧开窗减压髓核摘除术能够明显缓解患者术后的疼痛程度，提高手术疗效，术后患者恢复快。 

Clinical observation of two different surgical positions in the treatment of patients with lumbar disc herniation

  Objective  To compare the clinical effect of two kinds of open operation in the treatment of lumbar disc herniation under different position, and discuss the clinical advantage of simple kneeling operation table in the lamina decompression and decompression of nucleus pulpotomy under kneeling position.  Methods  A total of 132 patients with single lumbar disc herniation were treated with unilateral laminectomy decompression of Lumbar core. Patients were randomly divided into two groups. We used a numerical table extraction method to compare the surgical outcomes of patients treated with a simple kneeling table in the kneeling position (observation group, n=67) and patients treated with a conventional table in the prone position (control group, n=65). The operative time, intraoperative blood loss, postoperative bed time, postoperative hospital stay and complications of two groups were compared. The Oswestry dysfunction index (ODI), visual analogue score (VAS) and clinical efficacy (MacNab excellent and good rate) of the two groups before operation, 1 week after operation and 1, 3, 6 months after operation were compared.  Results  The operative time, intraoperative blood loss, bed time, hospital stay and the number of complications in the observation group were significantly less than those in the control group (P < 0.05). Compared with before surgery, ODI index and VAS score of 2 groups 1 week and 1, 3, 6 months after surgery were significantly lower than before surgery (P < 0.05). Compared with control group, ODI index and VAS score of observation group were lower than control group at 1 week and 1, 3, 6 months after surgery (P < 0.05). After 6 months of follow-up, the clinical efficacy of observation group was significantly better than control group (MacNab excellent and good rate: 91.04% vs 84.62%, P < 0.05).  Conclusion  Both methods are feasible for unilateral lamina decompression and removal of nucleus pulposus. Postoperative MRI showed that the responsible disc and nerve compression operation was satisfactory. But kneeling position of unilateral fenestration of the lamina and decompression of the nucleus pulposus can significantly relieve the postoperative pain of patients, improve the surgical effect, and postoperative patients recover quickly.
