闭合复位后椎体成型术治疗骨质疏松性椎体压缩骨折

Closed reduction in vertebroplasty for the treatment of osteoporosis vertebral compression fractures

目的:观察闭合复位后椎体成型术治疗骨质疏松性椎体压缩骨折的效果。方法:34例骨质疏松性椎体压缩骨折患者,利用手术床使患者椎体压缩骨折部位过伸,达到闭合复位目的,然后经皮穿刺行椎体成型术,根据术前和术后侧位X线片测量椎体高度压缩率、后凸畸形角度,并计算椎体高度恢复率和后凸畸形矫正率。结果:利用过伸体位闭合复位后再行椎体成型术可以使椎体前壁高度恢复(40.1±23.5)%,中间高度恢复(44.7±20.8)%,后壁高度恢复(15.3±12.4)%,后凸畸形角度矫正(42.5±29.3)%。结论:骨质疏松性椎体压缩骨折可利用过伸体位闭合复位后再行椎体成型术,可有效恢复椎体高度和矫正后凸畸形。

Objective：To determine the efficacy of closed reduction in vertebroplasty for the treatment of osteoporosis vertebral compression fractures.Method：34 patients with osteoporosis vertebral compression fractures were treated with closed reduction by extending the operating table,and then percutaneous vertebroplasty was performed on the fractured vertebra.The results were quantitatively evaluated ,according to the concept of estimated vertebral height loss and kyphotic angle of the vertebral compression fractures by plain standing lateral radiographs.Result：Vertebral compression fractures could be reducted by extending position before percutaneous vertebroplasty.The anterior vertebral height was restored （40.1±23.5）% ,the middle and posterior vertebral height were restored （44.7±20.8）%, （15.3±12.4）% respectively,and kyphosis angle was corrected （42.5±29.3）%.Conclusion：Closed reduction vertebroplasty is an efficacious method in the treatment of osteoporosis vertebral compression fractures and is able to restore the vertebral height and kyphosis angle.
