Bone union rate was higher with bilateral than unilateral TAS fixation (P less then 0.05). There were no complications regarding screw malposition. Deep wound infection was observed in 1 case in the C-group. CONCLUSIONS O-arm use improved TAS fixation accuracy. Blood loss was equivalent between the groups. O-arm-assisted TAS fixation did not prolong operative time despite the time required for setting and scanning. The O-arm is safe and useful for TAS fixation in atlantoaxial instability.
