SKY骨扩张器和球囊扩张治疗椎体压缩性骨折的疗效对比分析

Contrastive analysis of the curative effect of SKY-bone expander and balloon kyphoplasty in the treatment of painful vertebral body compression fracture

目的:SKY骨扩张器和球囊扩张行椎体后凸成形术治疗骨质疏松椎体压缩性骨折的疗效对比分析。方法:自2004年10月至2005年12月期间,SKY组11例患者11椎,T11～L3;球囊组18例患者25椎,T5～L4,在C型臂X线机引导下,采用经皮椎弓根穿刺,行椎体后凸成形术治疗骨质疏松椎体压缩性骨折。结果:SKY组:疼痛视觉模拟数字评分由术前的(8.4±1.3)分降至术后(2.6±1.1)分,后凸畸形Cobb角由术前的(27.35%±6.45%)矫正至术后的(10.83%±5.30%),每个椎体平均灌注骨水泥6.26 ml(3.0～9 ml)。球囊组:视觉模拟数字评分由术前的(8.6±1.7)分降至术后的(2.7±1.3)分,后凸畸形Cobb角由术前的(28.71%±9.45%)矫正至术后的(11.38%±6.87%),每个椎体平均灌注骨水泥5.3 ml(3.0～11 ml)。术后随访12～15个月,平均13.8个月,未发现有疼痛加剧及迟发性神经损伤表现。SKY组发生并发症2例,球囊组发生并发症4例。结论:比较VAS评分、椎体高度恢复及骨水泥灌注量来看基本相似,提示SKY骨扩张系统与球囊扩张系统疗效相近。

Objective： To analysis contrastively the therapecitic effect of transpedicular SKY-bone expander balloon kyphoplasty for osteoporotic vertebral compression fractures （VCFs）. Methods：From October 2004 to December 2005, eleven patients with painful VCFs, totally ii vertebrae from Tn to L3, were treated with transpedicular SKY-bone expander kyphoplasty under the guidance of C-armed imaging in SKY group; and eighteen patients, totally 25 vertebrae from T5 to L4, were treated with transpedicular balloon kyphoplasty in ballon group. Results： The Visual Analog Scale（VAS） in SKY guoup decreased significantly from （8.4 ± 1.3） preoperatively to （2.6 ± 1.1） post operatively. The mean kyphosis（Cobb＇s angle） was improved from （27.35%± 6.45%） to （10.83% ± 5.30%）. The average volume of PANA is 6.26ml（3.0 - 9 ml）; VAS in ballon group： decreased significantly from （8.6 ± 1.7） preoperatively to （2.7 ± 1.3） after post operatively. The mean kyphosis（Cobb＇s angle） was improved from （28.71% ± 9.45%） to （11.38%± 6.87%） post-operative. The average volume of PANA is 5.3 ml （3.0- 11 ml）. No exacerbation of pain and tardive nearitis were found in all patients follow-up; the mean period was 13.8 months （range from 12 to 15 months）.Two patients in SKY group and 4 patients in ballon group complicate with cement leakage. Conclusion：The curative effect of SKY-bone expander kyphoplasty and balloon kyphoplasty are close to each other.
