This constant subjection makes it highly susceptible to inflammation and lameness. The fetlock joint is the articulation between the cannon bone (third metacarpal and metatarsal bone in the forelimb and hindlimb respectively) and the long pastern … Even minor injuries tend to be visible on radiographs. This not only makes the gaits uncomfortable due to the jarring, but also increases the chance of arthritis and may shorten the animal's career.
