Objective To measure and analyze the important parameters related to percutaneous lumbar vertebroplasty simulated by computed tomography (CT). Methods Multi-sliced CT scanning of lumbar vertebrae was performed in 69 randomly selected patients. The data of a total of 345 vertebrae were obtained. The simulation of percutaneous lumbar vertebroplasty was conducted on post-processing workstation. The measurements of L1-L5 included the transverse and vertical distance ol the pedicles, the needle puncturing depth, the distance between the puncturing site and midline, etc. The statistic analysis was made with the help of SPSS13.0 software. Results The transverse and the vertical distance of L1-L5 pedicles was (6.60 ± 2.47) mm and (15.65 ± 1.44) min, respectively. The needle puncturing depth was (110.97 ± 9.63) mm and the distance between the puncturing site and midline was (59.30 ± 14.08) mm. Conclusion The parameters related to percutaneous lumbar vertebroplasty obtained from this study can provide basic and image anatomic data for the determination of puncture needle and puncturing route in performing percutaneous lumbar vertebroplasty.
