title: Three-dimensional image navigation system-assisted anterior cervical screw fixation for treatment of acute odontoid fracture.
abstract: This study is to investigate the role of three-dimensional image navigation system for surgical treatment of odontoid fracture. A total of 21 patients were enrolled in this study. The anterior cervical hollow screw fixation was performed for treatment of acute odontoid fracture under monitoring of isocentric C-arm three-dimensional navigation system (Iso-C 3D) navigation system. The postoperative follow-up investigation duration was 13.8 ± 4.4 months. Twenty patients with odontoid fracture had bone union without intraoperative and postoperative complications. No loosening, dislocation or fracture of screw occurred. The average healing time was from 3 to 4 months. The cervical postoperative organ function evaluation of patients was scored by Smiley-Webster scoring methods. Eighteen cases were scored as excellent; 2 cases were scored as fine; 1 case was scored as good; and no case was scored as poor. Iso-C 3D image navigation system-assisted anterior cervical screw fixation is an effective approach for treatment of odontoid fracture.
