单枚cage和单枚cage加单侧椎弓根螺钉内固定术治疗腰椎间盘突出并腰椎不稳症安全性观察

Safety Observationon Single Cage and Single Cage Plus Unilateral Pedicle Screw Fixation for the Treatment of Lumbar Disc Herniation Complicated With Lumbar Instability

目的：对单枚cage和单枚cage加单侧椎弓根螺钉内固定术治疗腰椎间盘突出并腰椎不稳症安全性进行探讨和分析。方法选取我院于2011年12月-2013年12月收治的50例腰椎间盘突出并腰椎不稳症患者，分成对照组和观察组，每组各25例，对照组患者采用单枚cage植骨融合术进行治疗，观察组患者采用单枚cage加单侧椎弓根螺钉内固定术进行治疗，记录患者的手术时间、术中出血量等，同时对患者进行为期一年的随访，观察患者的治疗效果，以及并发症发生情况。结果两组患者在手术时间、术中出血量等方面差异不明显（P〉0.05），通过对患者进行随访，观察组患者优良率较对照组高，在并发症方面，对照组中有7例患者出现cage脱出，观察组无，两组差异具有统计学意义（P〈0.05）。结论针对腰椎间盘突出并腰椎不稳症患者，单枚cage加单侧椎弓根螺钉内固定术具有较好的治疗效果，降低患者术后并发症。

Objective To discuss and analysis safety of single cage and single cage plus unilateral pedicle screw fixation in the treatment of lumbar disc herniation complicated with lumbar instability syndrome. Methods 50 lumbar disc herniation complicated with lumbar instability syndrome patients who were treated in our hospital from December 2011 to December 2013 were randomized into an observation group and a control group. The control group were treated by bone grafting with single cage treatment,and the observation group were treated with fixation of single cage plus unilateral pedicle screw. Recorded the operative time of patients intraoperative blood loss,etc.,at the same time to a one-year follow-up of patients,observed the therapeutic effect of patients,and complications. Results The two groups of patients in the operative time,amount of bleeding and other aspects of the difference was not statistically significant（P〉0.05）. According to one-year follow-up the patients in observation group were excellent and good rate was higher than the control group. In the complications,the control group had 7 patients appeared cage prolapse,and the observed group didn′t. And the difference was statistically significant（P〈0.05）. Conclusion For lumbar disc herniation complicated with lumbar instability syndrome patients. Single cage plus unilateral pedicle screw fixation is worth to be promoted and applied which has better treatment effect and reduce rate of complication.
