椎弓根螺钉内固定治疗不稳定胸腰椎骨折临床观察

Clinical observation of treating unstable thoracolumbar fractures patients by pedicle screw internal fixations

目的:观察椎弓根螺钉内固定治疗不稳定胸腰椎骨折的疗效。方法:选择我院2009年1月至2010年6月42例不稳定胸腰椎骨折的患者,其中22例采用椎弓根螺钉技术,设为观察组;20例采用传统手术方法的患者为对照组。随访6~12个月,两组术前及术后伤椎平均高度、后凸Cobb角、出血量、手术时间、住院时间。结果:两组术前及术后伤椎平均高度、后凸Cobb角差异有统计学意义(P<0.05)。两组术前及术后伤椎平均高度、后凸Cobb角组间差异无统计学意义(P>0.05)。观察组出血量明显少于对照组,手术时间与住院时间均较对照组短,两组比较差异具有显著性,有统计学意义(P<0.05)。结论:椎弓根螺钉内固定治疗不稳定胸腰椎骨折的疗效与传统手术相当,但可明显缩短手术时间与住院时间,减少术中出血,是治疗不稳定胸椎骨折的有效方法,可在临床推广应用。

Objective：To observe the clinical efficacy of pedicle screw internal fixation in the treatment for unstable thoracolumbarfractures patients.Methods： From Jan 2009 to June 2010,42 cases of unstable thoracolumbar fractures were selected and randomized into the observation group（22 cases） and the control group（20 cases）. The observation group were treated with pedicle screw internal fixation while the control group were treated with traditional operations. By following up of 6-12 months,mean height of injured vertebrae,Cobb^s angle,blood loss,operation time and hospital stay were compared. Results：Mter treatment, the two group showed significant difference in mean height of injured vertebrae and Cobb＇s angle. Before and after treatment,there was no statistical difference in mean height of injured vertebrae and Cobb＇s angle between two groups （P〉0.05）. However, there was statistical difference between the two group in blood loss, operation time and hospital stay（P〈0.05）. Conclusion： Pedicle screw internal fixation has a comparable efficacy in the treatment for unstable thoracolumbar fractures patients as same as traditional operations, however, it significantly decreased blood loss, operation time and hospital stay which is worthy of further promotion.
