膨胀式椎弓根螺钉内固定治疗腰椎病变的效果

Effect of expandable pedicle screw internal fixation of lumbar lesions

目的探讨膨胀式椎弓根螺钉内固定治疗腰椎病变的方法及治疗效果。方法选择2011年9月到2016年1月诊治的腰椎结核患者96例作为研究对象,根据随机抽签原则分为观察组与对照组各48例,观察组给予膨胀式椎弓根螺钉内固定治疗,对照组给予常规内固定手术治疗,记录两组预后与颈椎邻近节段椎间盘的变化影响。结果两组患者均完成手术。术后3、6个月,观察组患者植骨融合率和螺钉稳定性评分均显著高于对照组(P均<0. 01)。术后6个月,观察组患者并发症总发生率显著低于对照组(10. 42%vs 33. 33%,χ2=7. 375,P=0. 007)。结论膨胀式椎弓根螺钉内固定治疗腰椎结核病变能提高植骨融合率与螺钉稳定性,减少术后并发症的发生。

Objective To explore the impacts of expandable pedicle screw internal fixation of lumbar spinal disease.Methods Ninety-six patients with lumbar tuberculosis diagnosed and treated from September 2011 to January 2016 were selected as the research objects and were divided into observation group and control group according to random drawing method( n = 48,each). The expandable pedicle screw internal fixation was performed in observation group,while the conventional internal fixation was performed in control group. The prognosis and the changes of adjacent cervical intervertebral discs were observed in two groups. Results The operations were successfully completed in both groups. At postoperative 3-and 6-month,both bone graft fusion rates and screw stability score in observation group were significantly higher than those in control group( all P < 0. 01). At 6 months after operation,the incidence of pneumothorax,bedsore and other complications in observation group was significantly lower than that in control group( 10. 42% vs 33. 33%,χ2=7. 375,P = 0. 007). Conclusions In the treatment of lumbar tuberculosis,expansive pedicle screw fixation can improve the bone graft fusion rate and screw stability,reduce the incidence of postoperative complications. It has very good application values.
