Abstract
Objective To explore optimal puncture route and method for advance pierce accuracy when perform percutaneous vertebroplasty. Methods 248 cases (365 vertebrae )with osteoporotic vertebral body fractures in thoracic vertebral and lumbar vertebral were treated by percutaneous vertebroplasty. Total injured vertebraes were examined and measured puncture routes under CT before operation. Then according to measure route pierce and perform percutaneous vertebroplasty, when the pricker arrived preconceive place, take some radiographs obverse and side, after operation,scan injured vertebraes with CT again. Pierce accuracy was evaluated. Results 365 vertebrae were pierced successfully,the pierce successful rate was 100%. 324 vertebra piercing route were coincident with CT measure routes,coincident rate 88.8%. 41 vertebra piercing route weren' t coincident with CT measure routes, deflective rate was 11.2%. Conclusion CT measure puncture route and directing pierce was effective means when percutaneous vertebroplasty. Key words: Tomography, X-Ray computed; Percutaneous verebroplasty
