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 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.
When the horse puts weight on his leg, the fetlock sinks closer to the ground, which is a needed response as it helps to absorb the shock of the footfall. However, when the pasterns are too long or sloping it does not support the fetlock enough, and the fetlock may hyper-extend, possibly to the point where the ergot touches the ground.
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]
Barbaro broke his right hind leg in more than 20 places: [4] a broken cannon bone above the pastern, a broken sesamoid bone behind the fetlock, and a broken long pastern bone below the fetlock. The fetlock joint was dislocated, and his foot was left dangling loosely. Veteran jockey Edgar Prado immediately pulled Barbaro up and brought him to a ...
Beck missed the second half of the game, and backup quarterback Gunner Stockton took over and led the Bulldogs to the win in overtime. That secured them a spot in the College Football Playoff and ...
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 ...
