CONCLUSION:AXIS lateral mass screw plate system has the characteristic of stable,simple and safe and is suitable for the treatment of lower cervical spine injury.展开更多

Methods: A total of 48 cases (31 males and 17 females, aged from 18-72 years, mean: 41.3 years ) with thoracolumbar vertebrae burst fracture were treated by pedicle screw system since January 2004. According to the AO classification of thoracolumbar vertebrae fracture, there are 36 cases of Type A, 9 of Type B and 3 of Type C. Results: All patients were followed up for 6-25 months (average 12 months ), no secondary nerve root injury, spinal cord injury, loosening or breakage of pedicle screw were observed. The nerve function of 29 patients with cauda eqnina nerve injury was restored to different degrees. The vertebral body height returned to normal level and posterior process angle was rectified after operation. Conclusions: The vertebral pedicle screw internal fixation was technologically applicable, which can efficiently reposition and stablize the bursting fractured vertabrae, indirectly decompress canalis spinalis, maintain spine stablity, scatter stress of screw system, reduce the risk of loosening or breakage of screw and loss of vertebral height, and prevent the formation of posterior convex after operation.展开更多
