双C臂机在高龄椎体压缩骨折经皮椎体后凸成形术中的应用

目的探讨双C臂机在经皮椎体后凸成形术（PKP）治疗高龄椎体压缩骨折应用的优势。方法对79例高龄椎体压缩骨折患者行PKP，术中应用双c臂机47例（A组），单c臂机32例（B组）。分析两组手术时间、术中透视次数、穿刺次数及患者对手术过程满意度评分情况。结果手术时间：A组15～55（21±10）min，B组26～90（41±14）min，差异有统计学意义（P〈0．05）。术中透视次数：A组7～35（10．5±6．3）次，B组11～41（21．5±11．5）次，差异有统计学意义（P〈0．05）。术中穿刺次数：A组2～9（3．2±1．7）次，B组2～12（5．6±2．9）次，差异有统计学意义（P〈0．05）。手术过程满意度：A组3～9（6．6±2．4）分，B组手为2～5（3．2±1．1）分，差异有统计学意义（P〈0．05）。结论在高龄椎体压缩骨折PKP中，应用双C臂机可缩短手术时间，定位准确。

Application of double C arm X-ray machine in percutaneous kyphoplasty for treatment of elderly patients with vertebral compression fractures

Objective To discuss the advantages of application of the two table C arm machine in percutaneous ky- phoplasty（PKP） for treatment of elderly patients with vertebral compression fractures. Methods 79 cases of senile vertebral compression fractures underwent PKP. The application of double C arm machine was done in 47 cases （group A） , while 32 cases were done with single C arm machine （group B）. The operation times, number in per- spective, puncture times and score of satisfaction in the process of operation were compared. Results Operation time of group A was 15 -55 （21 ± 10） min, group B was 26 -90 （41 ± 14） min, there was significant differences （P 〈 O. 05）. Group A fluoroscopy number was 7 - 35 （ 10. 5 ± 6. 3） times, group B was 11 -41 （21.5 ± 11.5 ） times, there was significant differences（P 〈 0. 05 ）. Puncture time of group A was 2 - 9 （ 3.2± 1.7 ） times, group B was 2 - 12 （5.6 ± 2. 9） times, there was significant differences （P 〈 O. 05 ）. Group A score of satisfaction in the process of operation was 3 - 9 （6. 6 ± 2.4） points, group B was 2 - 5 （3.2± 1.1 ） points, there were statistical difference （ P 〈 0. 05）. Conclusions The application of double C arm X-ray machine in PKP with treatment of senile vertebral compression fractures can shorten the operation time with accurate positioning
