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. The fetlock joint is formed between the large metacarpal or metatarsal bone ( in the hindlimb and forelimb) and the proximal

Osselets refers to the inflammation of the connective tissue that is around the cannon bone and the fetlock joint. Inflammation can involve arthritis and can become a degenerative joint disease. The condition is a job risk for young thoroughbreds and is usually caused by stress and due to the trauma

Other contributors to the horse contracting the osselets include uneven tensions in the fetlock joint (usually due to poor or unbalanced footwear), irregular terrain and hasty conditioning. The latter often causes muscle fatigue and does not protect the horse's joints from tripping or "bad steps"

The horse will suffer pain in flexion, or when the animal presses on the affected front of the fetlock, it is indicative of osselets, as is the short and short march that is the result of when both frontal fetlocks are involved. (Shoulder problems can also cause a horse to move that way, so watch

When it first appears, it can be cured with rest, which is very important for treatment. To relieve inflammation, it is advisable to apply cold compresses for several days. Anti-inflammatory medications administered orally or by injection may also be used. Another treatment would be to inject

of repeated hard training in young horses. The first thing that appears on a horse with osselets is a swelling in the front part of the fetlock joint, there may be synovial strains on the sides of the joint. It is painful for the horse to flex the joint and usually causes lameness.

Osselets is caused by stress on the fetlock, which results in a stretching of the joint capsule. If the inflammation damages the cartilage of the joint, swelling in that area can become chronic and permanent. The joint capsule can also thicken.
