经皮椎体后凸成形术治疗胸腰椎骨折的临床疗效观察

目的：探讨经皮椎体后凸成形术治疗胸腰段椎体压缩性骨折的临床疗效.方法：2003年6月～2005年9月收治74例胸腰段椎体压缩性骨折患者,根据手术方法不同分为A组（椎体后凸成形术组,24例）和B组（椎弓根螺钉固定组,50例）.比较两组术前术后椎体前缘、中线、后缘高度变化,疼痛视觉模拟评分（visual analogue pain scale,VAS）,手术时间,出血量等方面的差异.结果：两组对椎体高度的恢复比较无统计学意义,A组的手术时间和出血量较B组少,差异有统计学意义（P＜0.01）,术后VAS评分A组较B组低（P＜0.01）.结论：经皮椎体后凸成形术与椎弓根螺钉系统治疗椎体压缩性骨折具有相似效果,但经皮椎体后凸成形术具有创伤小、手术时间短、出血量少等微创优点.

Study on the clinical effect of percutaneous kyphoplasty in the treatment of vertebral compression fracture

Objective:To study the clinical efficacy of percutaneous kyphoplasty(PKP) in the treatment of vertebral compression fracture.Method:74 patients with vertebral body compression fracture were collected who underwent percutaneous kyphoplasty(group A) or pedicle screw fixation(group B).The anterior height,midline height and posterior height of vertebrae body,visual analogue pain scale(VAS) were measured and compared preoperatively and postoperatively,operation time and amount of blood loss between 2 groups were also observed.Result:No statistically different was noted in vertebral height reduction between two groups,there were significantly different in the VAS(P<0.01) and in both operation time and amount of blood loss(P<0.01) between two groups.Conclusion:Percutaneous kyphoplasty has the similar clinical effect to pedicle screw system in treatment of vertebral body compression fracture,however it has the characteristic of minimal invasion,short operation time and less blood loss.
