Abstract

A 7-month-old female Bichon Frise, displaying neck pain and ataxia, was diagnosed with craniocervical junction abonormality (CJA), along with atlantoaxial subluxation. Surgical fixation of the atlantoaxial subluxation was performed, using cortical screws and bone cement, along with an odontoidectomy. After surgery, nonsteroidal anti-inflammatory medication was prescribed for pain control, and a loose bandage was applied to the neck. Mild ambulatory tetraparesis remained 1 week after surgery. Three weeks after surgery, the range of neck motion was near normal, and clinical signs had improved. CJA should be considered as a differential diagnosis in dogs with cervical myelopathy. Surgical stabilization using cortical screws and bone cement through a ventral approach can be successful in dogs with CJA and atlantoaxial subluxation.
