Decreased fetlock drop during the stance phase of the stride may be seen in cases of lameness, with the lamer leg producing less drop than the sound leg as the horse tries to relieve weight on the painful limb. [17] Decreased height to the stride (flight arc), or dragging of the toes, also indicates lameness, as the horse avoids bending its joints.
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]
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 suspensory is strained because fetlock is unable to straighten as horse loads the limb with weight. The pasterns are weak and unable to stabilize fetlock drop, so the horse is predisposed to ankle injuries, especially in speed events where the sesamoids are under extreme pressure from the pull of the suspensory.
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 ...

Poor conformation: long, sloping pasterns and a long-toe, low-heel shape to the hoof (seen commonly in Thoroughbreds) predisposes a horse to tendinitis. Poor trimming and shoeing: such as a farrier that causes a hoof shape that predisposed the horse to tendon injuries (such as a long-toe and low-heel), or one that shoes a horse with toe grabs ...
