经皮椎体后凸成形术与经皮椎体成形术治疗椎体压缩性骨折的效果及VAS评分分析

Analysis of effect and VAS scores of percutaneous kyphoplasty and percutaneous vertebroplasty in the treatment of vertebral compression fracture

目的探究经皮椎体后凸成形术(PKP)与经皮椎体成形术(PVP)治疗椎体压缩性骨折的效果及视觉模拟评分法(VAS)评分。方法60例椎体压缩性骨折患者,采用计算机随机抽签法分为对照组和观察组,每组30例。对照组患者采用经皮椎体成形术治疗,观察组患者采用经皮椎体后凸成形术治疗。比较两组患者伤椎高度百分比增加值与骨水泥注入量,手术前后伤椎Cobb角、椎体压缩率、伤椎VAS评分,手术不良事件发生情况。结果观察组患者伤椎高度百分比增加值(8.84±1.21)%高于对照组的(3.76±1.17)%,骨水泥注入量(5.83±2.26)ml多于对照组的(4.59±2.11)ml,差异具有统计学意义(P<0.05)。术前,两组患者伤椎Cobb角、椎体压缩率、伤椎VAS评分比较差异无统计学意义(P>0.05)。术后,观察组患者伤椎Cobb角小于对照组,椎体压缩率低于对照组,差异具有统计学意义(P<0.05);两组患者伤椎VAS评分比较差异无统计学意义(P>0.05)。观察组患者手术不良事件发生率为3.33%,明显低于对照组的23.33%,差异具有统计学意义(P<0.05)。结论相比于经皮椎体成形术,经皮椎体后凸成形术在椎体压缩性骨折的治疗中具有疗效突出、安全性佳的优势,值得优先选择。

Objective To investigate the effect and visual analogue scale(VAS)scores of percutaneous kyphoplasty(PKP)and percutaneous vertebroplasty(PVP)in the treatment of vertebral compression fracture.Methods A total of 60 patients with vertebral compression fracture were divided into control group and observation group according to computer random lottery method,with 30 cases in each group.The control group was treated with percutaneous vertebroplasty,and the observation group was treated with percutaneous kyphoplasty.The increment percentage of injured vertebra height,bone cement injection volume,Cobb angle of injured vertebrae,compression ratio of vertebral body,VAS score of injured vertebrae before and after operation,and occurrence of adverse events were compared between the two groups.Results The increment percentage of injured vertebra height(8.84±1.21)%of the observation group was higher than(3.76±1.17)%of the control group,and bone cement injection volume(5.83±2.26)ml was more than(4.59±2.11)ml of the control group.All the difference was statistically significant(P<0.05).Before operation,there was no statistically significant difference in Cobb angle of injured vertebrae,compression ratio of vertebral body,VAS score of injured vertebrae between the two groups(P>0.05).After operation,the Cobb angle of injured vertebrae of the observation group was smaller than that of the control group,and compression ratio of vertebral body was lower than that of the control group.All the difference was statistically significant(P<0.05).There was no statistically significant difference in VAS score of injured vertebrae between the two groups(P>0.05).The incidence of adverse events 3.33%of the observation group was obviously lower than 23.33%of the control group,and the difference was statistically significant(P<0.05).Conclusion Compared with percutaneous vertebroplasty,percutaneous kyphoplasty has the advantages of outstanding efficacy and good safety in the treatment of vertebral compression fractures,and it is worthy of optimization.
