国产球囊应用于经皮椎体后凸成形术的初步报告

Initial outcome and efficacy of the domestic-made balloon expender Kyphoplasty in the treatment of painful vertebral compression fractures

目的:应用国产球囊行经皮椎体后凸成形术(PKP),评价其在治疗疼痛性椎体压缩骨折中的临床应用效果。方法:2005.7～2007年9月收治的19例26椎严格选择的骨质疏松性椎体压缩骨折患者,应用国产可膨胀性扩骨球囊行PKP手术。观察患者手术前后疼痛和功能改善情况,观察骨水泥在椎体内的分布以及病椎的高度改变。结果:所有患者均安全完成手术,均采用单侧穿刺。本组患者术后VAS和ODI评分均较术前减少,结果有显著性差异(P<0.05)。X线片观察:本组单侧穿刺的26个椎体有23个见骨水泥越过中线到达椎体对侧,骨水泥充填满意。术后椎体前缘和中线高度恢复较明显。本组有2例3椎出现椎间隙少量渗漏,椎旁少量渗漏1例1椎,无临床症状。结论:应用国产球囊进行的PKP手术治疗疼痛性椎体压缩骨折有良好的临床疗效。

Objective： To evaluate the clincal application of the domestic-made balloon expander percutaneous kyphoplasty in the treatment of painful vertebral comperssion fractures. Methods： From July 2005 to Sep. 2007, 19 cases （26 vertebrae） suffered from the OVCFs were treated with domestic-made balloon expander PKP. Patients＇ pain relief and functional activities recovery were evaluated after operation, the distribution of the cement and the restoration of vertebral height were observed post-operation, All these patients were followed by telephone or clinic consults. Results： All cases successfully experienced procedures with unipedicle injection. The VAS and ODI scoring were both decreased significantly after operation（P〈0.05 ）. The anterior and midline heights of vertebrae restored significantly. Most of the cases with unipedicle injection can be seen a cross-midline cement distribution in the anterior-posterior position X ray film （23/26）. Conclusions： The domestic-made balloon expander PKP is efficacious and safe in the treatment of painful vertebral compression fractures.
