摘要
目的探讨经皮椎体后凸成形术（percutaneouskyphoplasty，PKP）治疗伴椎体内真空征的骨质疏松性椎体骨折和塌陷的临床疗效。方法回顾性分析2009年6月-2011年6月应用PKP治疗的31例伴椎体内真空征的骨质疏松性椎体骨折和塌陷患者的临床资料，分析本组患者的临床及影像学特点，通过测量术前、术后1周、术后3—6个月随访时骨折椎体高度变化，同时采用视觉模拟评分（visualanaloguescale，VAS）和Oswesrty功能障碍指数（Oswestry disabilityin—dex，ODI）评价PKP的临床疗效。结果31例患者均顺利完成手术，术后24h内患者腰背部疼痛均有明显缓解。术后1周和术后3～6个月随访时骨折椎体的高度分别为（17．2±4．2）inn、（16．8±5．1）mm，与术前（11．4±1．7）mlTI比较差异均有统计学意义（P〈0．01），两次随访差异无统计学意义（P〉0．05）。术后1周VAS评分、ODI分别为（2．8±1．7）分、31．6±8．4，与术前（8．6±1．3）分、78．3±8．5比较差异均有统计学意义（P〈0．01），术后3～6个月随访VAS评分、ODI分别为（2．3±0．8）分、（23．7±2．3），与术前比较差异有统计学意义（P〈0．01），与术后1周比较差异无统计学意义（P〉0．05）。结论PKP治疗伴椎体内真空征的骨质疏松性椎体骨折和塌陷患者，可有效缓解疼痛，恢复骨折椎高度，具有良好的临床效果。
Objective To investigate the clinical effect of percutaneous kyphoplasty （PKP） in treatment of osteoporotic vertebral fractures and collapse with intravertebral vacuum sign. Methods A retrospective study was conducted on the clinical and radiological data of 31 patients with osteoporotic ver- tebral fractures and collapse with intravcrtebral vacuum sign treated by PKP from June 2009 to June 2011. Vertebrae body variation, visual analog scale （VAS） and Oswestry disability index （ODI） before opera- tion, during follow-up at postoperative one week and at postoperative 3-6 months were used as outcome measurements. Results All the patients went through operations successfully and presented significant nlitigation of low back pain in 24 hours after operation. The vertebrae body height at postoperative one week [ （ 17.2 ±4.2） mm] and at postoperative 3-6 months [ （ 16.8 -± 5.1 ） mm] were statistically differ- ent from that before operation [ （ 11.4 ± 1.7 ） mm , P 〈 0.01 ] , while there was no statistical difference between the two follow-ups （P 〉 0.05 ）. VAS and ODI at postoperative one week [ （2.8 ± 1.7） points and （31.6 ± 8.4） points] were statistically different from those before operation [ （ 8.6 ± 1.3 ） points and （78.3 ± 8.5 ） points, P 〈 0.01 ]. VAS and ODI at postoperative 3-6 months [ （ 2.3 ± 0.8 ） points and （23.7 ± 2.3 ） points ] presented statistical differences from those before operation （P 〈 0.01 ）, but no statistical differences from those at postoperative one week （ P 〉 0.05 ）. Conclusion PKP obtains satisfactory clinical outcomes, for it relieves low back pain and restores vertebral body height.
