PKP微创治疗骨质疏松性胸腰椎压缩性骨折的疗效分析

Curative effect of percutaneous kyphoplasty on thoracolumbar vertebrae compression fractures of osteoporosis

目的探讨骨质疏松性胸腰椎压缩性骨折经球囊扩张椎体后凸成形术（PKP）治疗后的临床效果及PKP技术的安全性。方法对抚顺市中心医院骨科2011年4月-2013年2月,应用PKP技术治疗40例骨质疏松性胸腰椎压缩骨折的患者进行回顾分析。其中患者中男8例,女32例,伤椎共有43个。分析患者手术前后的临床资料和影像学资料,比较手术前后伤椎前缘高度、脊柱后凸Cobb角、疼痛视觉模拟评分（VAS）、Oswesty功能障碍指数（ODI）以及下腰痛评分（JOA）,最终进行数据分析比较。结果所有患者的手术都顺利进行,术后腰背部疼痛的症状得到明显缓解或消失,未出现手术并发症;术后24h VAS和ODI评分低于术前评分,而JOA评分高于术前评分;术后24h伤椎前缘高度高于术前,而Cobb角则低于术前（P〈0.05）。结论 PKP技术治疗骨质疏松性胸腰椎压缩骨折安全而有效。

Objective To study the clinical curative effects and security of percutaneous kyphoplasty in treating the thoracolumbar vertebrae compression fractures of osteoporosis. Methods A retrospective study was finished to review 40 cases（8 male and 32 female） of thoracolumbar vertebral compression fractures of osteoporosis treated by percutaneous kyphoplasty（PKP）. The vertebral height and Cobb angle of the fractured vertebral body, visual analogue scale（VAS）, Oswestry disability index（ODI） and Japanese orthopaedic association（JOA） were determined and analyzed before and after PKP. Results The operation of 40 cases was successful with immediate pain relief in varying degrees and without symptomatic complications. The values of VAS and ODI were lower post-PKP than pre-PKP, but higher for JOA value. The mean anterior height of vertebral body was higher post-PKP than pre-PKP, but lower for Cobb angle（ P 〈 0.05）. Conclusion PKP was safe and effective in therapy of thoracolumbar vertebrae compression fracture by percutaneous kyphoplasty.
