The following tendons are the main tendons found in the lower leg. When they pass over a joint, they are protected in a tendon sheath, which contains synovial fluid as a lubricant. Common digital extensor: the common digital extensor muscle becomes tendon in the bottom third of the radius and continues down the front of the leg. The tendon ...
The suspensory apparatus consists of the suspensory ligament, the check ligament, the deep digital flexor tendon, the superficial flexor tendon, the common digital extensor tendon and the sesamoid bones. [11] Horses use a group of ligaments, tendons and muscles known as the stay apparatus to "lock" major joints in the limbs, allowing them to ...
However, mature tendon contains cells that have a limited ability to regenerate. Following injury, tendon lays down type III collagen, or scar tissue, which is stronger than type I collagen but stiffer and less-elastic. This makes it less distensible and more likely to re-injure when the horse begins to stretch the tendon during strenuous work. [5]
Strain on the extensor tendon, the superficial digital flexor tendon branches, the collateral ligaments, and the distal sesamoidean ligaments are all common factors. If these tissues are stretched or torn, and the joint is unstabilized by the injury, new bone is produced to help to stabilize the joint.
A horse died at Churchill Downs in Louisville on Sunday, marking the latest in a string of recent deaths at the track. Rio Moon was euthanized after he injured his left front leg at the finish of ...
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] Interosseous ligaments: connect the cannon bone to each splint bone.
It can involve one or both hind legs of the horse. It is a spasmodic contraction of the lateral extensor tendons of the hind legs. An example of bilateral stringhalt in a horse: the hocks are spasmodically and rapidly flexed with the feet held high before quick placement back on the ground. The condition is more evident during turning and backing.
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. Considered a lameness when acute, and a blemish once healed, although the tendon is at greater risk for re-injury.
