Abstract：Objective To explore the application value of computer-assisted navigation in internal fixation of craniocervical junction malformation. Methods Clinical data of 25 patients with craniocervical junction malformation were analyzed retrospectively. All patients received internal fixation procedures under computer-assisted navigation and were followed up for at least 12 months. Japanese Orthopedic Association (JOA) scores were used to assess the patients' neurological function. Results C1 lateral mass and C2 pedicle screw fixation were performed in 15 patients, C1 and C2 transarticular screw fixation in 6 and transarticular screws combined with Brooks technique in 4. Bone graft fusion was performed in all the patients. JOA scores increased from 9.25±2.01 preoperatively to 14.36±1.97 at the last follow-up, significant differences was found between them (P<0.05). The screw placement was satisfactory in all the patients with no vascular or neural complications. Conclusion Computer-assisted navigation provides a great help for neurosurgeons in surgical treatment of craniocervical junction malformation, and has great potential in improving the screw placement accuracy, reducing operational damage and surgical complications.
