经皮球囊扩张椎体后凸成形术治疗骨质疏松性椎体骨折33例临床疗效分析

目的探讨经皮球囊扩张椎体后凸成形术(percutaneous kyphoplasty,PKP)治疗骨质疏松性椎体骨折的临床疗效。方法2004年3月~2007年2月DSA引导下采用PKP治疗骨质疏松性脊柱压缩性骨折33例共39椎,比较手术前后疼痛程度(VAS评分)及日常生活活动能力(Barthel指数)的变化;分别测量病椎椎体前、中、后缘的高度变化,并计算其与原椎体高度的比值,评价手术效果。结果术后患者VAS评分显著下降,均达到疼痛缓解(P<0.01);BI值明显增加(P<0.05);椎体前缘及中线高度明显增高(P<0.01)。未发现严重并发症。结论PKP治疗老年骨质疏松椎体骨折可以快速缓解疼痛,安全增加椎体高度,明显提高生活质量,是一种安全有效的方法。

Effect Analysis of Percutaneous Balloon Kyphoplasty for Osteoporotic Vertebral Fracture

Objective To analysis the effect of percutaneous balloon kyphoplasty(PKP) on the treatment of osteoporotic vertebral fracture. Methods 33 patients(39 vertebrae) suffered osteoporotic vertebral compression fracture(OVCF) were treated by PKP with the guide of DSA. Clinical effects were evaluated by observing the changes of visual analogues scales(VAS) and Barthel index(BI) as well as measuring the height of anterior,middle and posterior of the compression vertebrae.Results The VAS scores decreased and BI increased significantly after operation(P<0.01 or P<0.05).The anterior and middle height of compression vertebrae increased(P<0.01).No severe side-effect was observed.Conclusions PKP can relief the pain of osteoporotic vertebral compression fracture rapidly.It can also increase the height of vertebrae safely and improve the living quality of OVCF patients.
