Abstract
Objective To observe the morphological characteristics of thoracic pedicle and surrounding important structures of patients with scoliosis, and to evaluate the feasibility of pedicle rib unit with pedicle screw fixation used in scoliosis orthopedic. Methods 11 cases of scoliosis patients were preoperatively examined vertebral of orthopedic internal fixation by CT. The anatomic position and morphology of pedicle, pedicle rib unit, and the spinal cord were observed. In the navigation, the patients were treated with posterior pedicle screw internal fixation and bone grafting fusion. After the operation, the same segment was again performed CT scanning, and screw implant position was evaluated. Results The convex side of pedicle transverse diameter concave side was thin, of which the thinnest was 1.2mm. The convex side of pedicle was arc change, and the vertebral body was deviated from the concave side. The concave side of spinal was close to pedicle, and The convex side is deviated from the spinal pedicle. There were 25 (19.8%) screws completely partial out of pedicle in 126 pedicle screws, those were fixed with pedicle rib unit, but after the operation there were no neurovascular injury, and all cases maintained stable internal fixation. Conclusion Computer-assisted navigation with pedicle screw implantation used in scoliosis can improve the accuracy of screw placement. In severe deformity, screw can be body fixed by pedicle rib unit.关键词
