The inferior check ligament, also known as the distal check ligament or accessory ligament of the deep digital flexor tendon, runs from the palmar aspect of the knee to the deep digital flexor tendon approximately halfway down the length of the cannon bone. The main purpose of the ligament is to support and to prevent the over-extension of the ...
The limbs of the horse are structures made of dozens of bones, joints, muscles, tendons, and ligaments that support the weight of the equine body. They include two apparatuses: the suspensory apparatus, which carries much of the weight, prevents overextension of the joint and absorbs shock, and the stay apparatus , which locks major joints in ...
Bone spavin: osteoarthritis of the distal hock joints, which produces lameness and is sometimes seen as a visible, hard swelling on the inside of the hock joint. [61] A horse with bowed tendons. Bowed tendon: tendinitis of the superficial or deep digital flexor tendons, which leads to a "bowed" appearance when the tendon is seen in profile ...
Sesamoid bones: Bones embedded within a tendon. The horse's proximal digital sesamoids are simply called the "sesamoid bones" by horsemen, his distal digital sesamoid is referred to as the navicular bone. Ligaments and tendons hold the skeletal system together. Ligaments hold bones to bones and tendons hold bones to muscles.
Cross section of horse foot. The relevant areas are: 2. Second phalanx. 4. Coffin bone. 6. Navicular bone. 9. Deep digital flexor tendon. 16. Plantar cushion. 17. Hoof. Knowledge of equine forelimb anatomy is especially useful for understanding navicular syndrome. The navicular bone lies behind the coffin bone and under the small pastern bone ...
A totally ruptured superficial digital flexor tendon (SDFT) will cause a visible drop in the angle of the fetlock. [57] Catastrophic ruptured tendons account for as much as 3% of all tendon injuries. [58] Tendinitis is inflammation of a tendon. Tendons connect muscles to bone and normally have an elastic property so that they can stretch.
Tendons are classified as flexors (flex a joint) or extensors (extend a joint). However, some tendons will flex multiple joints while extending another (the flexor tendons of the hind limb, for example, will flex the fetlock, pastern, and coffin joint, but extend the hock joint). In this case, the tendons (and associated muscles) are named for ...
A combination of forces (e.g. the tension of the deep digital flexor tendon and the weight of the horse) result in the deep digital flexor tendon literally pulling the dorsal face of the coffin bone away from the inside of the hoof wall, which allows the coffin bone to rotate.
