Technique for equine cervical articular process joint injection

Abstract

Degenerative changes and osteochondrosis of articular processes are common sources of stiffness or pain in the equine cervical spine. Temporary relief of the clinical signs related to these maladies may be achieved by injecting corticosteroids into the joint. This is routinely done by ultrasound-guided needle placement. The cervical articular processes and joint form an easily identifiable sonographic landmark, a step-like echogenic surface described as having the appearance of a "chair."
