Strained Suspensory Ligaments in Horses

Strained suspensory ligaments are common in many types of performance horses, regardless of breed. Horses competing in jumping, racing, reining, barrel racing or other sports are often diagnosed and treated for suspensory ligament problems. While leg injuries can be career-ending for many horses, suspensory strains are typically treatable. although precautions must be taken to protect the ligament because it is not usually as strong as prior to the injury.

  1. The Suspensory Ligament

    • The suspensory ligament runs from the top, rear side of the canon bone. Approximately two-thirds down the length of the canon bone it divides into medial and lateral segments, which then connect to the proximal sesamoid bones on the fetlock. When a horse is moving rapidly it can overextend the fetlock joint and strain this ligament as a result. More severe cases can involve tearing of this ligament. A suspensory strain can happen on either the fore or hind legs.

    Diagnosis

    • Lameness on the affected limb is the first indication of a strained suspensory ligament. A mild strain may only show mild lameness lasting a few days, but a severe case can last months with the horse exhibiting extreme pain. Often the injury will induce swelling and heat in the leg along with a pain response when the area is touched. An ultrasound done by a veterinarian can usually confirm the diagnosis.

    Treatment

    • Animals with a strained suspensory ligament need to have their training halted until the injury has healed. Depending on the severity of the injury, the horse may need to be immobilized on stall rest. Common treatments include cold therapy, shock wave therapy and even stem cell therapy. Suspensory injuries may take anywhere from a few weeks to many months to heal properly.

    Prevention

    • A horse who's feet and legs have been looked after and maintained properly will be less likely to strain its suspensory ligament. This includes proper shoeing techniques, rest and leg protection when working. A properly conditioned horse, working on suitable footing that is neither too hard or too deep will also be less likely to overexert the ligaments and end up with an injury.
