摘要目的：探讨新型快速穿刺定位系统下经皮椎体后凸成形术（PKP）与传统PKP手术治疗腰椎椎体骨质疏松性压缩性骨折（OVCF）的临床疗效。方法回顾性分析2014年1月至2015年10月于沈阳军区总医院骨科行PKP手术的70例患者的临床资料，均为单节段腰椎椎体新鲜骨质疏松性压缩性骨折。术中均采用双侧经皮穿刺，根据术中穿刺定位方式不同，将其分为采用新型快速穿刺定位系统的PKP手术方法组（35例），传统PKP手术方法组（35例）。比较两组患者的平均手术时间、术中X线曝光次数、术前及术后次日视觉模拟评分（VAS）、椎体平均高度以及局部Cobb角改善情况。结果两组患者均由同一名外科医生顺利完成手术，新型快速穿刺定位系统PKP的手术时间、术中X线暴露次数分别为（43±16）min、（32±6）次，传统PKP组的手术时间、术中X线暴露次数分别为（62±13）min、（53±11）次，组间对比差异有统计学意义（P<0.05）。两组患者术后次日VAS评分均较术前明显降低（P<0.05），组间对比差异无统计学意义（P>0.05）。术后两组椎体平均高度及局部Cobb角较术前均有显著恢复（P<0.05），组间对比差异无统计学意义（P>0.05）。结论新型快速穿刺定位系统PKP手术与传统PKP手术比较，近期临床疗效相同，但前者具有手术时间短、术中透视次数少从而减少射线对患者及术者的辐射损伤等优点。

abstractsObjectiveTo investigate the clinical outcomes of a novel rapid puncture positioning system for percutaneous kyphoplasty and conventional method of percutaneous kyphoplasty on the treatment of osteoporotic vertebral compression fracture.MethodsA retrospective analysis from January 2014 to October 2015 in the department of orthopedics, general hospital of shenyang military region underwent PKP surgery in 70 patients, were single segment lumbar vertebrae fresh osteoporotic compression fracture. Intraoperative use of bilateral percutaneous puncture, according to the the puncture location during operation in different ways, which can be divided into PKP operation method using the new fast puncture positioning system of the group (35 cases), conventional PKP surgery group (35 cases), compared to the average operation time, two groups of patients in the X-ray exposure times, before and after the operation. The visual analogue scale, the average height of vertebral body, local improvement of Cobb angle.Results Two groups of patients were operated by the same surgeon successfully, the operation time of new fast puncture positioning system PKP, intraoperative X-ray exposure times respectively are (43±16) min, (32±6) times, the operation time of the traditional PKP, intraoperative X-ray exposure times respectively are (62±13) min, (53±11) times, between the two groups have significant difference (P<0.05). Two groups of postoperative day VAS score were significantly decreased (P<0.05), there was no significant difference between the two groups (P>0.05). The average height of two groups significantly restore vertebral body and local Cobb angle in preoperation after operation (P<0.05), the difference between groups was not significant (P>0.05).Conclusion A new fast puncture positioning system PKP surgery and PKP surgery, clinical curative effect is the same, but the former has the advantages of shorter operation time, less intraoperative fluoroscopy times so as to reduce radiation damage to the patient and the patient's X-ray.
