Abstract:
OBJECTIVETo evaluate the technique of C1-C2 transarticular screw fixation for atlantoaxial instability or dislocation.
METHODSAmong 14 patients with atlantoaxial instability, 10 were male and 4 patients were female, with an average age of 38.6 years ranging from 17 to 62 years. All patients were treated by internal fixation with transarticular screws.
RESULTSThere were 28 screws applied in 14 patients. All patients were followed up. The average follow-up period was 16 months (range, 9 to 35 months). The postoperative JOA score was ranging from 13.8 to 15.8 with the average score of (14.50 +/- 0.66) and the improved rate of (76.12 +/- 4.94)%. No spinal injury and vertical artery injury was found and osseous fusion was completed in all patients.
CONCLUSIONThe technique of C1-C2 transarticular screw fixation is one of the best treatments for atlantoaxial instability. Without the help of structural bone graft and aided internal fixation, morselized cancellous bone graft can acquire effective osseous fusion.
