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).
Osselets: swelling on the front surface of the fetlock joints of the front legs, caused by traumatic arthritis of the fetlock joints. [65] Ringbone: boney proliferation around the pastern. May be articular (osteoarthritis) or non-articular. The articular forms can affect the pastern or coffin joints, and can cause lameness. Shoe boil: see ...
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.
Knee joint of dog. Piece showing knee joint of dog. An untreated hygroma can develop into a large swelling that stresses the surrounding skin and becomes an open wound with the possibility of infection that is much more difficult to treat. In most cases, a hygroma is a single occurrence for an animal, but other individuals will have repeated ...
On this horse, the ergot is a small point at the back of each fetlock Ergot on a heavy horse with feathers. The ergot is a small callosity (Calcar metacarpeum and Calcar metatarseum) on the underside of the fetlock of a horse or other equine. Some equines have them on all four fetlocks; others have few or no detectable ergots.
Yet, as it advances, distinct signs like heat, swelling, and pain in the suspensory ligaments emerge. An altered gait or a flat-footed stance due to a sinking fetlock joint are also indicative of the disease.
The treatment of equine lameness is a complex subject. Lameness in horses has a variety of causes, and treatment must be tailored to the type and degree of injury, as well as the financial capabilities of the owner. Treatment may be applied locally, systemically, or intralesionally, and the strategy for treatment may change as healing progresses.
In some cases, swelling continues through the udder or sheath and along the subcutaneous abdominal veins. In the early stages, the swelling is primarily a "pitting oedema"; in other words, if pressed, a depression remains in the skin of the limb. The affected leg may reach twice or even three times its normal size, and may be very sensitive to ...
