The front of the cannon bone will feel warm. Continuous exercise will increase lameness and cause a choppy gait. Thickening of the plantar tarsal ligament, which starts just under the point of the hock and runs to the head of the cannon bone. An enlargement below the point of the hock can be observed. A rupture due to injury or strain.
Poor conformation can also contribute to the condition.
Bony enlargements below the fetlock. More common in forelegs. Hard swelling in the splint bone area. Poor conformation and nutrition imbalance also contribute. Inhibited return of blood flow in lower legs.
