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]
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.
Prognosis can also vary depending on type and severity as well. However some signs of a positive prognosis may include, a horse being able to stay up and not lying down too much, keeping the horse quiet can also help with the healing factor, if the horse appears to be back to normal within 24 hours the prognosis outlook is better.
Curb is defined in older literature as enlargement secondary to inflammation and thickening of the long plantar ligament in horses. [1] However, with the widespread use of diagnostic ultrasonography in equine medicine, curb has been redefined as a collection of soft tissue injuries of the distal plantar hock region.
The prognosis for a horse with navicular syndrome is guarded. Many times the horse does not return to its former level of competition. Others are retired. Eventually all horses with the syndrome will need to lessen the strenuousness of their work, but with proper management, a horse with navicular syndrome can remain useful for some time.
Knee injuries, the second most common non-fatal career-ending injury, force 16% of racehorses to retire. [47] A ruptured tendon usually refers to the complete separation of a tendon. Tendon separation results in a complete loss of the tendon fibers, a marked increase in tendon cross-sectional area, and loss of support in the limb. [56]
Over 3000 privately owned horses and dogs have been treated with autologous adipose-derived stem cells. The efficacy of these treatments has been shown in double-blind clinical trials for dogs with osteoarthritis of the hip and elbow and horses with tendon damage. [92] [93] Race horses are especially prone to injuries of the tendon and ligaments.
Initial treatment of a bowed tendon should concentrate on anti-inflammatory therapies, including cold water or ice therapy, and anti-inflammatory medications on the direction of a veterinarian. The horse should be confined to a small area until the severity of the injury can be assessed with ultrasound. Standing bandages are helpful, but care ...
