摘要
目的 比较Jack椎体扩张器后凸成形术（dilator-kyphoplasty,DKP）与Kyphon球囊扩张后凸成形术（balloon-kyphoplasty,BKP）治疗骨质疏松性椎体压缩骨折的临床疗效.方法 2007年5月至2009年3月,对23例（26椎）老年骨质疏松性椎体压缩骨折行DKP,对29例（29椎）行BKP.比较手术时间、术中出血量、骨水泥注射量,观察骨水泥在椎体内的分布以及手术前后病椎高度和Cobb角的改变,评价疼痛视觉模拟评分（visual analogue scales,VAS）和Oswestry功能障碍指数（Oswestry disa bility index,ODI）.结果 所有患者均安全完成手术.两组手术时间、出血量、骨水泥注入量相比较,差异均无统计学意义（P＞0.05）.两组患者均全部获得随访,DKP组随访5～18个月,平均9.2个月;BKP组随访6～20个月,平均10.3个月.两组术后椎体高度、Cobb角、疼痛VAS评分及ODI评分均较术前改善（P＜0.05）.DKP组在恢复椎体前缘高度和矫正Cobb角方面明显优于BKP组（P＜0.01）.DKP组有1例（1椎）出现椎体旁少最渗漏（3.8%）;BKP组有5例（5椎）出现骨水泥渗漏（17.2%）.结论 DKP和BKP均可有效治疗老年骨质疏松性椎体压缩骨折.DKP在恢复椎体前缘高度及矫正Cobb角上明显优于BKP.
Objective To compare the clinical outcomes of dilator-kyphoplasty （DKP） and balloonkyphoplasty （BKP） in treatment of osteoporotic vertebral compression fractures. Methods From May 2007 to March 2009, 23 cases with 26 vertebrae were treated with DKP, while 29 cases with 29 vertebrae were treated with BKP procedures. The operating time, bleeding volume and injecting volume of cement were recorded during operation. The distribution of cement, the restoration of vertebral height and Cobb angle were observed. The patients＇ visual analogue scales （VAS） score and Oswestry disability index （ODI） score were evaluated after operation. Results There were no differences in operative time, bleeding volume of every vertebrae and cement injected volume between these two groups （P〉0.05）. The vertebral height, Cobb angle, VAS and ODI scores were significantly improved than those of pre-operation in these two groups （P〈0.05）. The height of the anterior vertebrae and Cobb angle in DKP groups were restored significantly than those in BKP groups （P〈 0.05）. There were 1 case （1 vertebra, 3.8%） underwent cement leakage in DKP groups and 5 cases （5 vertebrae, 17.2%） in BKP groups. Conclusion DKP and BKP were effective in the treatment of osteoporotic vertebral compression fractures. The height of the anterior vertebrae and Cobb angle in DKP groups were restored significantly than those in BKP groups.
