经皮椎体成形术和经皮椎体后凸成形术治疗骨质疏松性椎体压缩骨折的临床效果

Clinical efficacy of percutaneous vertebroplasty and percutaneous kyphoplasty in treatment of osteoporotic vertebral compression fractures

目的比较经皮椎体成形术(PVP)和经皮椎体后凸成形术(PKP)治疗骨质疏松性椎体压缩骨折的临床疗效。方法将100例骨质疏松性椎体压缩骨折患者随机均分为PVP组和PKP组,记录两组手术前后VAS疼痛评分、椎体高度压缩率、Cobb角以及并发症的发生情况等。结果两组术后VAS疼痛评分、椎体高度压缩率及Cobb角均较术前改善(P<0.05)。与PVP组相比,PKP组术后椎体高度压缩率及Cobb角减小,椎体周围骨水泥渗漏的发生率降低(P<0.05或P<0.01)。结论 PVP和PKP治疗骨质疏松性椎体压缩骨折均具有良好的临床效果。但PKP具有术后恢复快、并发症发生率低等优势。

Objective To compare the clinical efficacy of percutaneous vertebroplasty（PVP） and percutaneous kyphoplasty（PKP） in the treatment of osteoporotic vertebral compression fractures （OVCF）. Methods A total of 100 patients with OVCF was equally randomized into two groups of PVP and PKP. The VAS pain score, compression rate of vertebral height, Cobb＇s angle and complications were recorded. Results The VAS pain score, compression rate of vertebral height and Cobb＇s angle were significantly improved after operation than those before operation in groups of PVP and PKP（P〈0. 05）. Compared with group PVP, the compression rate of vertebral height, Cobb＇s angle and incidence of bone cement leakage were decreased in group PKP（P〈0. 05 or P〈0. 01）. Conclusion Both PVP and PKP in the treatment of patients with OVCF achieve satisfactory clinical outcomes. But compared with PVP, PKP has the advantages of quicker recovery and less complications after operation.
