单侧与双侧PKP治疗OVCF的疗效分析

目的比较单侧与双侧经椎弓根穿刺椎体后凸成形术(PKP)治疗骨质疏松性椎体压缩性骨折(OVCF)的疗效。方法选择2009年12月至2010年12月间采用经皮球囊扩张椎体后凸成形术治疗骨质疏松性椎体压缩性骨折患者34例。其中19例经单侧椎弓根穿刺,15例经双侧椎弓根穿刺。按照VAS疼痛评分、影像学资料分别对患者疼痛、椎体高度和Cobb’s角进行疗效比较。结果所有手术均顺利完成,无严重手术并发症。术后10～12个月随访,两种穿刺方法VAS疼痛评分、影像学资料较术前均有改善(P<0.05)。术后1年单侧组与双侧组比较,伤椎前缘的高度、椎体后凸Cobb’s角有显著性差异(P<0.05),VAS疼痛评分无显著性差异(P>0.05)。结论①单侧与双侧经椎弓根穿刺椎体后凸成形术治疗骨质疏松性椎体压缩性骨折均是有效的。②双侧穿刺在伤椎前缘高度的恢复、椎体后凸Cobb’s角的改善方面优于单侧穿刺。

Analysis of Therapeutic Effect of Unilateral and Bilateral Percutaneous Kyphoplasty(PKP) in Treating Osteoporotic Vertebral Compression Fracture(OVCF)

Objective To compare the clinical effect of unilateral and bilateral percutaneous kyphoplasty(PKP) in treating osteoporotic vertebral compression fracture(OVCF).Methods 34 patients with OVCF from December 2009 to December 2010 were treated with PKP,among whom 19 cases were with unilateral and 15 cases were with bilateral.The pain,height of vertebral body and Cobb’s angle were compared according to VAS scoring,imaging data of unilateral and bilateral.Results All the operations were successful without serious complications.After 10 ~ 12 months’ follow-up,the VAS scoring,imaging data of both two methods improved significantly than preoperation(P <0.05).The differences of height of vertebral body and Cobb’s angle 1 year after operation between unilateral group and bilateral group had statistical significance(P <0.05),while the VAS scores had no statistical significance(P >0.05).Conclusions ①Both unilateral and bilateral paracentesis are effective in treating osteoporotic vertebral compression fracture.②Bilateral percutaneous kyphoplasty are better than unilateral in the recovery of vertebral body height and the improvement of Cobb’s angle.
