A 4-year-old, Quarter Horse mare presented with a history of hind limb neurologic dysfunction of two-week duration. History, physical and neurologic examinations were consistent with a compressive lesion affecting the cervical spinal cord. Osteoarthritic lesions were identified between C6 and C7 with survey radiographs. Cerebral spinal fluid analysis and myelogram confirmed cervical stenotic myelopathy between C6-C7 as the cause of the neurologic signs observed. Ventral interbody fusion surgery ultimately decreased neurologic dysfunction.
