中文摘要：

目的探讨分析经皮球囊扩张椎体后凸成形术（PKP）治疗骨质疏松性胸腰椎压缩性骨折的临床疗效及手术并发症。方法自2015年1月至2016年6月收治42例骨质疏松性胸腰椎压缩性骨折患者均应用PKP治疗。术前、术后1d、术后3个月比较疼痛视觉模拟评分（VAS）、椎体高度。结果所有患者均获得随访,随访时间3~18个月,平均9.3个月。住院时间5~7d,平均5.5d。分析结果显示VAS由术前的（7.2±2.3）分降为末次随访的（2.2±1.5）分,差异有统计学意义（P〈0.01）。术后的伤椎椎体前缘高度较术前明显增加,差异有统计学意义（P〈0.05）。结论 PKP术对可明显缓解骨质疏松性胸腰椎压缩性骨折的症状,有创伤小、手术难度小等诸多优点,值得推广。

英文摘要：

Objective To evaluate the clinical efficacy and complications in the intraoperative use of PKP in the treatment of osteoporotic thoracolumbar vertebral compression fractures.Methods From January 2014 to June 2015, forty-two patients with osteoporotic thoracolumbar vertebral compression fractures treated by PKP were analyzed retrospectively.The VAS was evaluated preoperatively ,1 day after operation and during 6-month follow-up respectively.All patients＇ vertebra height was recorded before and after operation.Results They were followed up after the operation.All of 46 patients were available for a mean follow-up of 9.3 months （range 3-18 months）.The average length of stay was 5.5 d （range 5-7 days）.At final follow-up, mean VAS was 2.2±1.5, significantly lower than that of the preoperative （7.2±2.3）（P〈0.01）.The height of fractured vertebra at 1 day after operation was significantly higher than that before operation （P〈0.05）.Conclusion The therapeutic effect of PKP for the treatment of osteoporotic thoracolumbar vertebral compression fractures is better, which can effectively alleviate the pain, and effectively improve the function.Thus, it is an alternative operation for the treatment of osteoporotic thoracolumbar vertebral compression fractures, which is worth popularizing.
