A possible explanation could be that surgeries performed in lumbosacral spine were mainly for degenerative disc diseases, which often required spinal fusion, while in the thoracolumbar spine, where operations were more likely for vertebral fracture, fusion were not always necessary. It was observed in one case that CT scan failed to show a clear gap around screw, even though an obvious double halo was found on X-ray and the extraction torque was 0.06Nm (Fig. My question isShould I contact the surgeon who performed my surgery back in N.Y.? If you know or suspect that something has gone wrong with your spinal hardware, youll want to contact the surgeon that performed your initial operation. 16 Other complications of ACDF include spinal cord injury (<1%), nerve root injury (0.9%), post-operative haematoma (1.7%), recurrent laryngeal nerve injury (2%-4%), vertebral artery injury (<1%), surgical wound infection The presence of wear debris [23] was reported to induce osteolysis leading to screw loosening. In this process, two or more vertebrae are fused together and healed into one solid bone. The main role of the screw in lumbar fusion is to reduce the motion of the spine and to conduct the stabilization, whereas screw loosening is observed in quite a few literature works (7)(8)(9). To the best of our knowledge, no study has evaluated such risk factors according to the extraction torque in vivo. The minimal time interval between primary surgery to screw removal was 18months.
