Transarticular C1-C2 screws fixation for traumatic atlanto-axial instability

ABSTRACT

This is a retrospective study of 11 patients diagnosed with traumatic atlanto axial instability that was treated with transarticular C1-C2 screws but without supplemental posterior wiring. After a mean follow up of 25 months. Ten patients [91%] reported no pain related to their neck, while 1 patient had residual neck pain that was aggravated by neck movement. The overall fusion rate was [91%] as 10 patients out of 11 patients showed a definite bridging fusion mass on X-rays. In conclusion using posterior C1-C2 fusion by transarticular screws with morselized autograft but without additional wiring for traumatic atlantoaxial instability is associated with excellent clinical and radiological outcomes without the need for external halo immobilization
