椎体后凸成形术及椎体成形术治疗骨质疏松性椎体骨折的疗效对比

目的 探讨椎体后凸成形术和椎体成形术治疗骨质疏松性椎体骨折的疗效。方法 根据手术方式不同将80例骨质疏松性椎体骨折患者分为经皮椎体成形术组(PVP组)和经皮椎体后凸成形术组(PKP组),于术前、术后1周、术后6个月采用疼痛视觉模拟评分(VAS评分)和SF-36量表行疼痛评分及健康状况评分,并观察患者椎体后凸角度、椎体压缩率及骨水泥渗漏发生情况。结果 与术前相比,两组VAS评分显著降低,SF-36评分显著升高,差异均有统计学意义(P<0.05),椎体后凸角度、椎体压缩率均减少,差异均有统计学意义(P<0.05)。术后1周、术后6个月VAS评分、SF-36评分及并发症发生率两组间差异无统计学意义(P>0.05)。结论 PVP及PKP均有良好的临床疗效。对于椎体复位,PKP较PVP更具优势。

Comparative study of treatment efficacy of percutaneous vertebroplasty and kyphoplastyon osteoporotic vertebral fractures

Objective To investigate the clinical effects of percutaneous vertebroplasty(PVP) and percutaneous kyphoplasty(PKP) in the treatment of osteoporotic vertebral compression fractures(OVCF). Methods According to the surgical options, 80 patients with OVCFwere divided into the percutaneous vertebroplasty group(PVP group) and the percutaneous kyphoplasty group(PKP group). The local pain and health status were evaluated withvisual analog scale(VAS) of pain and SF-36scalebefore operation and at 1 week and 6 months after operation. At the same time, the posterior convex angle, vertebral compression rate of all patientsand situation of bone cement leakage were recorded. Results The VAS scores of both groups after operation were apparently lower, and the SF-36 scores were largely higher than those before operation, with statistically significant differences(P<0.05), and the posterior convex angle and vertebral compression rate after operation were significantly improved(P<0.05). There was no significant difference in the postoperative SF-36 score, VAS score and complications at 1 week and 6 months after operation between the two groups(P>0.05). Conclusion The surgicaloptions of PVP and PKP both have good clinical effects in the treatment of OVCF, and PKP is superior to PVP in the vertebrae reduction.
