Definition: The hock joint is the largest joint on the horse's hind legs. The joint is made of several small bones, the most prominent being the Os Calsis which gives the hock its angular shape. The strength of the hocks is very important as this is the most active joint in the horse’s hind legs. Poorly conformed hocks may make the horse susceptible to break down if the horse is worked very hard.
Pronunciation: h aw k
