Atlantoaxial stability was evaluated in 12 surgically stabilized dogs and 6 control dogs after odontoidectomy and dorsal atlantoaxial ligament separation. The atlantoaxial instabilities were stabilized with transarticular pins from a ventral approach. Cancellous bone grafts harvested from the proximal humerus were used to promote joint fusion. Good joint stability, alignment, and early fusion were documented clinically, radiographically, and histopathologically in stabilized dogs. Because of our consistent results despite variable pin angles, we recommend this technique for use in dogs with atlantoaxial instability requiring surgical stabilization.
