Fetlock joint: the joint between the cannon bone and the pastern. Fetlock is the common name in horses, large animals, and sometimes dogs for the metacarpophalangeal and metatarsophalangeal joints (MCPJ and MTPJ). Although it somewhat resembles the human ankle in appearance, the joint is homologous to the ball of the foot.
The dislocation caused destruction of all of the supporting ligaments to the back of the fetlock and pastern joint, making the ankle unstable and requiring surgery. [4] Three days after the catastrophic injury Larry Bramlage, DVM, of Rood and Riddle performed a fetlock anthrodesis, fusing the bones to eliminate the fetlock joint.
The pastern is a part of the leg of a horse between the fetlock and the top of the hoof. It incorporates the long pastern bone (proximal phalanx) and the short pastern bone (middle phalanx), which are held together by two sets of paired ligaments to form the pastern joint (proximal interphalangeal joint).
Correct Trimming and Shoeing: a good farrier will trim the horse's feet correctly, preserving the pastern-hoof angle, and will properly support the horse’s heels. Bandaging: using properly applied exercise bandages can help prevent the overextension of the fetlock.
Fetlock luxations account for 91% of all fatal luxation injuries. Due to the construction of the fetlock joint, luxation will result in either a complete rupture of the flexor tendons and suspensory ligament or a lateral disarticulation. The joint capsule may also be completely ruptured and the articular portion of the bones exposed to view. [51]
Rood & Riddle has been called the "Mayo Clinic for horses" and is a full-service equine referral center. In a 2002 interview, Rood said the hospital treated about 10,000 cases each year, which included 4,600 surgeries and 1,293 arthroscopies. Their most common cases were colic and pneumonia.

Skeleton of the lower forelimb. Each forelimb of the horse runs from the scapula or shoulder blade to the third phalanx (coffin or pedal) bones. In between are the humerus (arm), radius (forearm), elbow joint, ulna (elbow), carpus (knee) bones and joint, large metacarpal (cannon), small metacarpal (splint), sesamoid, fetlock joint, first phalanx (long pastern), pastern joint, second phalanx ...
