SKy经皮穿刺椎体后凸成形术治疗陈旧性骨质疏松椎体骨折

SKy percutaneous kyphoplasty( SKy-PKP) in treatment of old osteoporosis vertebral compression fractures

目的探讨SKy经皮穿刺椎体后凸成形术(SKy-PKP)治疗陈旧性骨质疏松椎体骨折的临床疗效。方法回顾性分析2015年1月~2017年1月35例陈旧性骨质疏松椎体骨折(40个椎体)并且接受SKy-PKP术的患者,平均随访6个月。患者术前行骨折椎体及邻近节段X线片、CT、MRI等检查。术前、术后评估患者疼痛评分(VAS评分),Oswestry功能障碍指数(ODI),测量术前及术后椎体前缘、中线、后缘高度及后凸角;采用SPSS18.0软件进行数据分析。结果本组患者手术均顺利,无严重并发症发生。术前与术后VAS评分平均从7.9下降至3.3,ODI从66.0%下降至36.9%;椎体前缘、中线高度较术前均有明显恢复,分别恢复4.1mm,5.8mm(P<0.05),椎体后缘无明显变化(P>0.05)。术后后凸角比术前减小,平均矫正6.8°。结论 SKy-PKP术是治疗骨质疏松椎体骨折的一种安全、有效的方法,疗效满意,椎体高度和后凸矫正效果明显。

Objective To analyse the clinic effect of SKy percutaneous kyphoplasty（ SKy-PKP） in treatment of old osteoporosis vertebral compression fractures. Methods 35 cases（ 40 vertebras） of symptomatic old osteoporos-is vertebral compression fractures were treated by SKy-PKP from January 2015 to January 2017,with an average follow-up of 6.0 months. The patients underwent suspected segmental X-ray,CT and MRI. The pain level of each patient was assessed,both before and after the procedure,a visual analog scale（ VAS） and Oswestry disability index were used to reflect the ability of daily life. SPSS18. 0 software was used to analyze data. The anterior body height,middle line body height,posterior body height and kyphotic angle changes between pre-and post-treatment were measured on a lateral radiograph. Results The postoperative average pain score reduced from 7. 9 to 3. 3 and ODI reduced from 66. 0% to 36. 9%. There were no serious complications. The mean corrected angle and anterior vertebral height and middle line vertebral height between preand post-treatment were 6. 8° and 4. 1 mm and 5. 8 mm respectively. Conclusion SKy-PKP is a reasonable procedure for the treatment of old osteoporosis vertebral compression fractures. The curative effect is satisfactory. The improvement of the vertebral height and kyphosis correction is obvious.
