自制定位引导器在经皮椎体成形术中的应用效果

The application effectiveness of homemade positioning conductor in percutaneous vertebroplasty

目的探讨自制定位引导器在经皮椎体成形术中的应用效果。方法将35例采用经皮椎体成形术治疗的胸腰椎骨折患者按照住院日期奇偶数分为对照组(住院日期为偶数,采用依据经验体表画线辅助手术治疗,18例)和观察组(住院日期为奇数,采用自制定位引导器辅助手术治疗,17例)。记录两组术中透视次数、手术穿刺时间、穿刺锥调整次数,判定定位穿刺准确率。结果术中透视次数、手术穿刺时间、穿刺锥调整次数观察组均明显少(短)于对照组(P<0.05),表明定位穿刺准确率观察组明显高于对照组。结论在经皮椎体成形术中应用自制定位引导器可提高手术定位穿刺准确率,提升手术操作便利性,同时可缩短手术穿刺时间,减少术中X线透视次数。

Objective To investigate the application effectiveness of homemade positioning conductor in percutaneous vertebroplasty(PVP).Methods Thirty-five patients of thoracolumbar fractures who were performed with PVP were randomly divided into two groups,according to the odevity of hosipitalization date.The control group(18 cases,the hosipitalization date was even number)were adopted with drawing line on body surface assisted the surgery accordance with experienc;and the observation group(18 cases,the hosipitalization date was odd number)were performed with homemade positioning conductor assisted surgery.The frequency of fluoroscopy and the time of puncturing,the frequency of regulating the puncturing cone were recored,and the the accuracy rate of positioning puncture was assessed.Results The frequency of fluoroscopy,the time of puncturing and the times of regulating the puncturing cone in the observation group were significantly less(shorter)than those of the control group(P<0.05),which showed that the observation group was significantly higher than the control group in the accuracy of positioning puncture.Conclusions The application of homemade positioning conductor in PVP surgery can improve the accuracy of positioning puncture during the operation,improve the convenience of operation,meanwhile shorten the time of operation puncture,decrease the number of intraoperative X-ray fluoroscopy.
