1、Sky膨胀型骨扩张器在骨质疏松性椎体压缩骨折后凸成形中的初步临床应用作者：王桂春，陆建忠，李秋实，朱孔瑞【摘要】目的：探讨Sky骨扩张器经皮椎体后凸成形术治疗骨质疏松性椎体压缩骨折的近期临床疗效。方法：对18例24个椎体的骨质疏松性压缩骨折患者，应用Sky骨扩张器进行经皮椎体后凸成形治疗，观察患者术前、术后疼痛视觉模拟评分(VAS)，测量手术前后各病椎椎体前缘、后缘高度，进行比较和统计学分析。结果：24个椎体均为单侧经椎弓根穿刺成功完成手术，失血量平均每例约15ml，每个椎体平均手术时间47min，每个椎体注入骨水泥(4

2、.2±0．8)ml，分布均超过中线。2例骨水泥外漏为沿针道返流，但无临床症状。所有患者疼痛缓解，VAS评分术前(8．2±1．6)分，术后3天(3．1±2．3)分；随访5个月～23个月，随访VAS(2．7±2．8)分(P＜0．01)。伤椎前缘平均高度术前17．35mm，术后20．05mm(P<0.01);伤椎后缘平均高度木前22．78mm，术后23．49mm(P＜0．05)。结论：Sky骨扩张器是经皮脊柱后凸成形术的新型器械，是治疗骨质疏松性椎体压缩骨折的安全、有效的微创治疗方法。【关键词】经皮椎体后凸成形术；骨质疏
