Abstract:
BACKGROUND:Traditional internal fixation for thoracolumbar vertebral fractures easily causes poor vertebral reduction, and postoperative vertebral height loss easily appears.
OBJECTIVE:To analyze the feasibility of lateral-position pedicle screw placement in spinal surgeryvia combined anterior-posterior approaches.
METHODS: A total of 36 cases undergoing spinal surgical operation in the Baoji City Chinese Medicine Hospital from February 2013 to October 2014 were enroled in this study. The patients were divided into two groups according to the method of repair. 18 patients in the control group received prone-position pedicle screw placement, and 18 patients in the experimental group received lateral-position pedicle screw placementvia combined anterior-posterior approaches. Postoperative CT and X-ray examinations compared the adverse rate of screw placement and the rate of nerve root injury between the two groups. Operation time, length of stay, time of beginning movement, intraoperative blood loss and American Spinal Injury Association impairment scale score were compared between the two groups.
RESULTS AND CONCLUSION:Significant differences in the adverse rate of screw placement and the rate of nerve root injury were detected between the two groups (P < 0.05), and the adverse rate of screw placement and the rate of nerve root injury were better in the experimental group than in the control group. Operation time, length of stay, and time of beginning movement were significantly better in the experimental group than in the control group (P < 0.05). Intraoperative blood loss was significantly lower in the experimental group than in the control group (P < 0.05). American Spinal Injury Association impairment scale scores were significantly higher in the experimental group than in the control group (P < 0.05). These findings confirm that lateral-position pedicle screw placementvia combined anterior-posterior approaches in spinal surgery can reduce intraoperative trauma, shorten the length of hospital stay, and promote functional recovery of spinal cord.
