骨水泥不同分布对PVP术后疗效的影响

Effect of Different Distribution of Bone Cement on Post-PVP Outcomes

目的观察骨水泥在椎体内不同位置分布对PVP术后疗效的影响。方法选取2014年3月至2015年3月本院收治的因椎体骨质疏松性压缩骨折住院行椎体成形术(PVP)患者,随机分为A组(采用上下终板灌注)和B组采(用非上下终板灌注)。比较两组患者手术后及随访疗效。结果 B组患者术后3、6、9、12个月伤椎椎体前缘压缩率与A组比较差异有统计学意义(P<0.05);B组术后的ODI、VAS评分显著高于A组(P<0.05);在术后6、12个月B组伤椎节脊柱Cobb角显著高于A组(P<0.05)。结论 PVP术后骨水泥上下终板灌注的手术效果更佳,更能减轻疼痛,减少椎体塌陷,防止后期脊柱后凸畸形,获得更好的远期疗效。

Objective To observe the effect of different locations of bone cement on the vertebral body after PVP. Methods A retrospective analysis of vertebroplasty(PVP)for osteoporotic compression fractures of the vertebral body from March 2014 to March 2015 was performed,and the results were compared between the two groups after operation and follow-up. Results There was significant difference between the 3,6,9 and 12 months after operation in group B(P<0.05),and the ODI and VAS scores in group B were higher than that in group A(P<0.05),and Cobb angle of B group was higher than that of group A at 6 and 12 months after operation(P<0.05). ConclusionThe effect of the upper and lower end plate perfusion of bone cement after PVP was better,it can reduce the pain and the collapse of the vertebral body,prevent the late spinal kyphosis,with better long-term effect.
