Atlanto-axial instability in a five month Old English Bulldog

Abstract

Atlantoaxial subluxation was first described in dogs in the late 1960s. Since that time multiple surgical methods of stabilization of the atlantoaxial joints have been reported, all with varying degrees of success. There is currently no one single accepted surgical procedure for correction of atlantoaxial subluxation. A five month English Bulldog presented to the Cornell University Hospital for Animals Neurology Service with an atlantoaxial subluxation, which was diagnosed on physical exam, MRI, and CT findings. The dog's atlantoaxial joint was surgically explored and stabilized using a novel stabilization technique which included a previously reported ventral surgical procedure and a new dorsal procedure. This presentation will outline the historical findings, diagnosis, and treatment of atlantoaxial instability in dogs. The English Bulldog's surgical procedure and recovery will be discussed in further depth.
