Case Description- A 10-year-old trakhener gelding presented to the Cornell University Equine Hospital for evaluation of progressively poor performance and hind limb weakness. The horse had been purchased and imported from Europe within the last six months, and was healthy at the time of acquisition. Clinical Findings- Abnormalities detected on physical examination included bilaterally symmetric cervical muscle atrophy, decreased lateral range of motion in the neck, and a C6-T2 spinal ataxia. Initial diagnostics included a blood chemistry, hemogram, and cervical radiographs, all of which were unremarkable. Myelogram was positive for dynamic, extradural spinal cord compression and mild synovial osteoarthritis at C6-7. Treatment and Outcome- Surgery resulted in the successful implantation of a kerf cut cylinder at the C6-7 intervertebral joint space. Postoperative care included systemic antibiotics, analgesics, and gastroprotectants. Radiographs performed four days and two weeks postoperatively showed an intact, properly placed, implant. The patient was discharged to the owners 20 days postoperatively and is currently doing well. Clinical Relevance- This case includes a discussion of cervical vertebral stenotic myelopathy, surgical intervertebral joint arthrosis, postoperative management, and procedural risks and outcomes.
