【摘要】Objective To compare the clinical effect of percutaneous pedicle screw insertion via intersection of facet and center line of transverse process and traditional percutaneous placement method in treatment of lumbar spine compression fractures.Methods A prospective study was performed on 56 patients with lumbar spine compression fractures without neurologic deficits admitted from January to May in 2014.There were 26 males and 30 females,aged from 20 to 47 years (mean,37.1 years).Adjacent vertebrae above and below the fractured vertebra were instrumented,and each pair of pedicle screws of every instrumented vertebra were instrumented via traditional entry point (Group A) or via intersection of facet and center line of transverse process (Group B) according to the random number table.Preoperative and postoperative anterior vertebral height and Cobb angle were measured,and every pedicle screw was graded according to facet violation grading system.Intraoperative data were compared between the two groups,including time of determining entry point,frequency of fluorescence to determine entry point,patient radiation exposure,doctor
