Influence of bone cement volume and dispersion index on early efficacy of percutaneous kyphoplasty

目的分析骨水泥量及分布指数对经皮椎体后凸成形术早期疗效的影响。方法50例骨质疏松性椎体骨折患者接受经皮椎体后凸成形术,以骨水泥量或分布指数中位数为临界值,比较高、低骨水泥量组及高、低骨水泥分布指数组术后疼痛VAS评分及Oswestry功能障碍指数问卷表(ODI)评分。结果高、低骨水泥量组间VAS、ODI评分差异无统计学意义(P>0.05),而高骨水泥分布指数组术后VAS评分显著低于低骨水泥分布指数组(P<0.01)。结论骨水泥量多少不影响椎体后凸成形术的早期疗效,而骨水泥分布指数增加可减轻术后疼痛。

Objective To investigate the influence of bone cement volume and dispersion index on early efficacy of percutaneous kyphoplasty(PCKP).Methods Fifty patients with osteoporotic vertebral fractures undergoing PCKP were divided into high and low volume and dispersion index based on median value of bone cement.The visual analogue scale(VAS)and Oswestry disability index(ODI)score were compared between these groups.Results VAS and ODI scores were comparable between high and low bone cement volume group(P>0.05),while VAS score was lower in high dispersion index group than in low dispersion index group(P<0.01).Conclusion Bone cement volume seems not to affect the early efficacy of PCKP,while high dispersion index of bone cement can alleviate postoperative pain.
