Bucked shins are an enlargement of the front part of the cannon bone between the knee and the fetlock joints. This enlargement usually occurs in the front legs and is due to trauma to the periosteum, most often caused by concussion.
The periosteum is a thin membrane that covers the bone. The condition usually causes soreness, but if periostitis occurs, new bone growth can occur, and the shin will have a bucked appearance. Bucked shins usually occur in young horses.
