Placement and complications of cervical pedicle screws in 144 cervical trauma patients using pedicle axis view techniques by fluoroscope

摘要: Cervical pedicle screw fixation is an effective procedure for stabilising unstable motion segment; however, it has generally been considered too risky due to the potential injury neurovascular structures, such as spinal cord, nerve roots or vertebral arteries. Since 1995, we have treated 144 cervical patients with screws using a fluoroscopy-assisted axis view technique. The purpose of this study was investigate efficacy technique in accurately placing treat injuries, and ensuing clinical outcomes complications. accuracy placement postoperatively examined by axial computed tomography scans oblique radiographs. Solid posterior bony fusion without secondary dislodgement accomplished 96% all cases. Of 620 inserted, 57 (9.2%) demonstrated exposure ( 50% outside pedicle). There one case which probe penetrated artery further complication transient radiculopathy. Pre- postoperative tracheotomy required 20 (13.9%) patients. However, tracheotomies were easily performed, because those underwent surgery alone external fixation. provided good results few complications but careful surgical needed safely insert more improvement imaging navigation system expected.
