Stabilization of Atlantoaxial Subluxation in the Dog, Using the Nuchal Ligament

Abstract

A technique for the stabilization of atlantoaxial subluxation in the dog was developed. The technique involved use of the nuchal ligament as a means of securing the spinous process of the axis to the dorsal arch of the atlas. Two cases were typical atlantoaxial subluxation in toy-breed dogs, and 2 cases were traumatic subluxation secondary to fracture of the axis in dogs of large breeds. On the basis of the results in these cases, it was concluded that the technique has advantages over techniques in which wire or nonmetallic suture material is utilized for stabilization.
