Abstract:
Objective To assess the efficiency of total laminectomy and transpedicular screw placement techniques and a thoroughly decompression with a three column fixation device on the early cervical spine cord injury.Methods 27 patients were operated successfully with total cervical laminectomy through transpedicular screw techniques.Precise measurements of all cervical spines were made by postoperative CT scan of pedicle dimensions,angulation,and offset relative to the lateral mass boundaries.And meanwhile,cortical integrity and neurovascular injury were then assessed by obtaining postoperative computed tomography scans of each patient.Results Using manual techniques,220 pedicles were instrumented and all the cases were followed up between three to twenty-four months.The postoperative gradations were obviously better than the preoperative evaluation.Regardless of the technique used,the vertebral artery was the structure most likely to be injured.Conclusion Insufficient correlation between different surgeons' assessments of surface landmarks attests to the inadequacy of screw insertion techniques in the cervical spine based on such specific topographic.At the early stage of cervical spinal cord injury,using total laminonectomy decompression through cervical screws techniques to reconstruct spinal alignment could improve the prognosis of patients.
