摘　　要：目的比较自制透视定位器与普通定位方法对老年骨质疏松性椎体压缩性骨折患者行经皮椎体后凸成形术时，其接受的x线投照量、手术时间的差异。方法选取68例（75椎）老年骨质疏松性椎体压缩性骨折患者，均进行经皮椎体后凸成形术。按照随机数字表法将患者分为两组，采用自制透视定位器34例（39椎）（试验组），采用普通定位方法34例（36椎）（对照组），对两组患者接受的x线投照量、手术时间及术后椎体高度恢复晴况进行比较。结果所有患者手术穿刺均获成功，试验组确定穿刺点时的x线投照量[（196．92±10．93）mA·s]明显低于对照组[（826．67±25．89）mA·s]，手术时间[（30．82±0．56）min]明显短于对照组[（56．08±0．93）min]，差异均有统计学意义（P〈0．05）。术后3个月，两组伤椎前缘高度升高值比较差异无统计学意义[（2．47±0．18）mm比（2．09±0．21）mm]（P〉0．05）。结论自制定位器能缩短手术时间，减少x线投照量。自制透视定位器用于经皮椎体后凸成形术治疗老年骨质疏松性椎体压缩性骨折是行之有效的方法。Objective To compare the difference of X ray projection volume and operative time when using two different positioning methods in percutaneous kyphoplasty to treat elderly osteoporotic vertebral compression fracture （OVCF） patients. Methods Sixty-eight （75 vertebraes） patients who underwent percutaneous kyphoplasty were divided into two groups, 34 cases （39 vertebraes） underwent self-made fluoremeter （group A） comparing with the other 34 patients （36 vertebraes） without using locator （group B）. X ray projection volume, operation time and recovery of exterior edge height were compared. Results During locating the puncture point, the X ray projection volume in group A [ （ 196.92 ± 10.93） mA·s ] was significantly less than that in group B [ （ 826.67 ± 25.89） mA·s ] （P 〈 0.05 ）. The operation time in group A [ （30.82 ± 0.56） min] was significantly less than that in group B [ （56.08 ± 0.93 ） rain ] （P 〈 0.05 ）. The recovery of exterior edge height at 3 months after operation had no significant difference between two groups [ （2.47 ±0. 18 ） mm vs. （2.09 ±0.21 ） mm ] （P 〉 0.05 ）. Conclusions The self-made fluoremeter can save operation time and reduce the X ray projection volume. It is an effective way to treat OVCF patients undergoing percutaneous kyphoplasty.
