Abstract
Objective To compare the clinical curative effects of balloon vertebroplasty reinforced by injectable calcium sulfate cement (CSC) and posterolateral fusion after short-segment pedicle screw fixation through the fractured vertebra in treatment ofthoracolumbar burmt fractures.Methods 60 cases ofthoracolumbar burst fracture were randomly divided into two groups in our hospital in Jan 2012 to Dec 2014,each group had 30 cases,and one group were treated by balloon expansion vertebral body enhancement combined with short segmental injury vertebral pedicle screw internal fixation,and the others underwent posterolateral fusion in addition to short-segment pedicle screw fixation through the fractured vertebr.The two groups were compared at preoperation,1 week postoperation and the last follow-up in terms of visual analogue scale (VAS),Oswestry disability index (ODI),middle height ratio of the injured vertebra and the sagittal Cobb angle.Results Compared with the preoperative,two groups of patients with postoperative VAS scores and ODI scores were significantly lower,postoperative pain situation improved significantly (P＜0.01);After 1 year,vertebral body height than in the middle of the enhanced group were significantly higher than bone graft fusion and vertebral strengthening postoperative 1 year group of sagittal Cobb Angle of bone graft fusion was much higher than group,prompt postoperative vertebral body to enhance curative effect was better than that of bone graft fusion group,rectify lost less,the differences were statistically significant (P＜0.01),all no internal fixation failure occurred.Conclusion CSC balloon expansion vertebral body enhancement and posterolateral bone graft fusion are effective treatment ofthoracolumbar burst fracture,but CSC vertebral strengthening early can better recovery of injured vertebral height,increase the stability of injured vertebral and vertebral body strength and reduce the correct degree of loss,preserved section of the spinal movement function.关键词
