Fetlock Arthritis, Osselets

The fetlock is a high motion joint under tremendous mechanical stress in performance horses. This is particularly true in race horses who commonly suffer disease and injury to this joint, chip fractures, and osteoarthritis. Any injury to this joint usually starts the development of osteoarthritis.

The term “osselets” refers to a specific problem of young race horses in which there is irritation to the front part of the fetlock joint, inflammation and increased joint fluid, and in chronic cases, the development of a bony bump. Rest is the cornerstone to arresting the cycle of arthritis in these horses.
