经伤椎椎弓根植骨结合膨胀型椎弓根钉固定治疗老年性胸腰椎骨折

Transvertebral bone grafting combined inflating pedicle screws internal fixation for thoracolumbarfracture in eldly patients

目的探讨经伤椎椎弓根椎体内植骨结合膨胀型椎弓根钉固定治疗老年性胸腰椎骨折的临床疗效。方法对2012年2月—2013年4月收治的43例行后路经伤椎椎弓根椎体内植骨结合膨胀型椎弓根螺钉复位内固定术的老年胸腰椎骨折患者的临床资料进行回顾性分析,观察椎弓根螺钉的稳定性、脊柱融合率、术前及术后疼痛视觉模拟量表(VAS)评分、伤椎Cobb角、椎体前后缘高度改善情况。结果 43例患者术后平均随访1年,所有患者螺钉稳定性及骨融合良好。VAS评分、Cobb角矫正、椎体前后缘高度均较术前明显改善。结论经椎弓根椎体内植骨结合膨胀型椎弓根钉固定治疗老年性胸腰椎骨折具有促进骨折愈合、改善疼痛及减少术后后凸畸形的良好临床疗效,是一种治疗老年骨质疏松性胸腰椎骨折安全、可靠、有效的治疗手段。

Objective To explore the clinical effect of transvertebral bone grafting combined inflating pedicle screws internal fixation for thoracolumbar fracture in eldly patients.Methods Clinical materials of 43 thoracolumbar fracture eldly patients received the transvertebral bone grafting combined inflating pedicle screws internal fixation for thoracolumbar fracture were analyzed.Screw stability,spinal fusion rate,per-and postoperation visual analogue scale（VAS）scores,Cobb′s angle and vertebral height improvement was observed.ResultsAll patients were followed up,at a mean time of 1year,screw stability and good bone fusion were observed in all patients.VAS score,Cobb′s angle,vertebral height correction significantly improved compared with preoperative period.Conclusion Transvertebral bone grafting combined inflating pedicle screws internal fixation for thoracolumbar fracture in eldly patients can enhance the fracture healing,improve pain and reduce postoperative kyphosis.
