单侧椎间融合内固定治疗腰椎间盘突出症的手术效果

Surgical Effect of Unilateral Pedicle Screw Fixation and Lumbar Interbody Fusion in the Treatment of Lumbar Disc Herniation

目的分析椎间盘突出症椎间融合后单侧内固定的手术效果。方法随机选取2007年8月—2014年12月收治的腰椎间盘突出症患者68例,均给予椎间植骨融合术治疗,随机分为单侧内固定治疗的观察组(34例)和双侧内固定治疗的对照组(34例),观察与对比两组患者手术治疗情况。结果与对照组比较,观察组患者的手术时间、术中出血量、术后引流量均低于对照组,差异有统计学意义(P<0.05);术后二组患者的椎间隙曲度、融合率以及JOA评分、MACMAB疗效评定的差异均无统计学意义。结论研究表明,单侧椎间融合内固定治疗手术创伤小,可取得与双侧手术相当的近远期疗效。

Objective To analyze the surgical effect of unilateral pedicle screw fixation and lumbar interbody fusion in the treatment of lumbar disc herniation. Methods 68 patients with lumbar disc herniation admitted from August 2007 to December 2014 were randomly divided into the observation group and the control group with 34 cases in each. The observation group were treated by the unilateral pedicle screw fixation and lumbar interbody fusion, while the control group were treated by bilateral pedicle screw fixation and lumbar interbody fusion. And the surgical treatment effect of the two groups was observed and compared. Results Compared to the control group, the observation group had shorter operative time, less intraoperative blood loss and less postoperative drainage, the differences were statistically significant（P〈 0.05）. The differences in intervertebral curvature, fusion rate, JOA score and result of MACMAB between the groups after surgery were not statistically significant. Conclusion The study shows that for the treatment of lumbar disc herniation, unilateral pedicle screw fixation and lumbar interbody fusion have smaller trauma, but can obtain the same short-term and long-term effects as bilateral pedicle screw fixation and lumbar interbody fusion.
