title: Atlantoaxial instability treated with transarticular screw fixation.
abstract: We treated 11 patients with atlantoaxial instability using transarticular posterior screw fixation and lateral bone grafting. A posterior bone graft was added in eight patients. The results showed good reduction and a stable fixation. After 6 months ten patients had regained almost 70% of rotation and did not notice any significant limitation.
