过伸体位复位经皮椎体成形术治疗老年骨质疏松性椎体压缩骨折

Percutaneous vertebroplasty after hyper-extending position in the treatment of elderly osteoporotic vertebral compression fractures

目的探讨过伸体位复位经皮椎体成形术(PVP)治疗老年骨质疏松性椎体压缩骨折的临床效果。方法采用过伸体位复位PVP治疗43例老年骨质疏松性椎体压缩骨折患者(47椎),对比手术前后患者VAS评分、伤椎高度及Cobb角的变化,评价治疗效果。结果 43例均顺利完成手术。手术时间30～55 min,伤椎骨水泥注入量2～6 ml,无骨水泥渗漏发生。术后VAS评分、伤椎高度及Cobb角与术前比较均明显改善,差异均有统计学意义(P<0.001)。患者均获得随访,时间20～50 d。无再发椎体骨折者。结论过伸体位复位PVP治疗老年骨质疏松性椎体压缩骨折,能部分恢复伤椎高度及矫正后凸畸形,止痛效果确切,临床效果满意。

Objective To investigate the clinical outcomes of percutaneous vertebroplasty after hyper-extending position in the treatment of elderly osteoporotic vertebral compression fractures. Methods The 43 cases elderly osteoporotic vertebral compression fractures（ 47 vertebrae） were treated by percutaneous vertebroplasty after hyper-extending position. The VAS,Cobb angle and vertebral height before and after operation were compared,treatment effects were analysed. Results All 43 patients finished surgery successfully. Operation time was 30 ～ 55 min,and injection volume of bone cement was 2 ～ 6 ml,and no leakage of bone cement was found. There were significant differences in the VAS,Cobb angle and vertebral height at the preoperation and postoperation（ P 0. 001）. All partients were followed up for 20 ～ 50 d. No further vertebral fracture occurred. Conclusions The operation is simple and convenient,which can partially restore vertebral height and correcte kyphosis. It has obvious analgesic effect and strong practicability that the clinical results are satisfactory.
