Where is the fetlock joint on a horse?

A ‘horses fetlock’ is a name of a joint between the horses cannon bone and pastern bone and is ‘the ankle’ of a horse. At the rear of the fetlock joint is a small bone called the sesamoid. Unlike humans ankles, the horse’s leg has no muscles and are in fact more similar to our fingers than our arms or legs.

The hind end fetlock plays a critical role in supporting the horse’s weight. As a result, lameness can be seen even with minor injuries. Lameness is relatively easy to notice in this joint because the soft tissue structures of the fetlock have limited protective coverings (i.e. fascia and fatty tissue).
