ATLANTOAXIAL SUBLUXATION IN DOGS

Subluxation of the atlantoaxial joint is most commonly seen in small-b reed dogs and may occur subsequent to a variety of lesions of the dens or atlantoaxial ligaments. In each case, dorsal displacement of the a xis results in compression of the cervical spinal cord. Surgical corre ction is recommended for most patients, and recovery is possible even in severe cases if compression of the spinal cord can be relieved and the joint can be reduced and stabilized. Dorsal and ventral stabilizat ion procedures have been described, but complications are common. Vent ral stabilization with lag screws may result in the most favorable sur gical outcome with fewest complications of the commonly reported surgi cal techniques.
