Osselet is arthritis in the fetlock joint of a horse, caused by trauma. [1] Osselets usually occur in the front legs of the horse, because there is more strain and concussion on the fetlock there than in the hind legs. The arthritis will occur at the joint between the cannon bone and large pastern bone, at the front of the fetlock.
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 ...
Shock wave therapy is sometimes employed in the case of splint bone fracture or stress fractures to the cannon bones, to improve blood flow to the area. Fractures within a joint, such as chip fractures in the knee, hock, or fetlock, require arthroscopic surgery to prevent secondary arthritis of that joint.
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 ...
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).
Tendons attach muscles and bone, and are classified as flexors (flex a joint) or extensors (extend a joint). However, some tendons will flex multiple joints and extend another (the flexor tendons of the hind limb, for example, will flex the fetlock, pastern, and coffin joint, but extend the hock joint).
The first factor is compression of the navicular bone under the DDF tendon and the back of the small pastern bone. Repeated compression in this area can cause cartilage degeneration, with the cartilage flattening and gradually becoming less springy and shock-absorbing. It may also begin to erode.
A flexion test is a preliminary veterinary procedure performed on a horse, generally during a prepurchase or a lameness exam. The purpose is to accentuate any pain that may be associated with a joint or soft-tissue structure, allowing the practitioner to localize a lameness to a specific area, or to alert a practitioner to the presence of sub-clinical disease that may be present during a pre ...
