While the fetlock is sometimes colloquially referred to as an "ankle", even by horse experts, that terminology is misleading. The ankle joint in humans corresponds to the hock of horses. The fetlock is a metacarpo- or metatarsophalangeal joint which corresponds to the human upper knuckle, such as that on the ball of the foot. This usage likely ...
Points of a horse. Equine anatomy encompasses the gross and microscopic anatomy of horses, ponies and other equids, including donkeys, mules and zebras.While all anatomical features of equids are described in the same terms as for other animals by the International Committee on Veterinary Gross Anatomical Nomenclature in the book Nomina Anatomica Veterinaria, there are many horse-specific ...
The fetlock joint is supported by group of lower leg ligaments, tendons and bones known as the suspensory apparatus. [11] This apparatus carries much of the weight of the horse, both when standing and while moving, and prevents the fetlock joint from hyperextending, especially when the joint is bearing weight.
Fetlock is the common name for the metacarpophalangeal and metatarsophalangeal joints of horses, is a rotatory joint that can exhibit the greatest range of motion of any equine joint. [3] The fetlock joint is formed between the large metacarpal or metatarsal bone ( in the hindlimb and forelimb) and the proximal sesamoid bones. [4] Relation with ...
The main purpose of the suspensory is to support the fetlock joint, preventing it from overextending. Injury to this ligament is an important cause of lameness in performance horses. The suspensory is a modified muscle, the equine equivalent of the interosseous muscle, which contains both tendon fibers and residual muscle fibers. [1]
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).
Fairly commonly injured by horses doing fast work, the DDFT is round in cross section. Superficial digital flexor: Runs down the back of the leg, behind the carpus and cannon, branches below the fetlock and inserts into the distal side of the 1st phalanx and proximal side of the 2nd phalanx. Flexes the elbow, carpus and lower joints.
The SDFT branches below the fetlock, creating a sling under the back of the joint. Thus, overextension of the fetlock is more likely to overstretch the SDFT than the DDFT, which simply travels straight down behind the fetlock and pastern, to attach to the coffin bone .
