abstract
The subluxated atlantoaxial joint of a tetraplegic Yorkshire terrier was reduced and secured in position by means of cross pinning applied via a dorsal approach. The dog made a very satisfactory recovery. The surgical technique for this new procedure is described. Further investigations into the biomechanics of such fixation, and long term follow-up of treated cases, will be required to evaluate accurately the value of this technique.
