Bowed Tendons

Bowed Tendons: A bowed tendon is a term used for a tendon after a horse has sustained an injury that caused the tendon fibers to be torn, and then healed with a “bowed” appearance.These are an examples of two bowed tendons, but these horses are still racing! In fact, they are racing very well and the one that looks worse (bigger) is actually racing better than the other.

When the SDFT goes through an acute injury, which can be minor tears of the fibers (looks kind of like “swiss cheese” in the ultrasound) or one big tear, the tendon starts a healing process usually in which most of the tissue that fills in is connective tissue.

When the tendon heals it’s usually bigger and not as “strong” as it was before the injury, so it is prone to more tears. Actually most of the “new” tears happen above or below the previously healed area because this is an area with more scar tissue and less elastic fibers so it is more static then elastic. Most of the time, surgery to cut the Annular Ligament that constricts the movement of the tendon is warranted, if the tendon has not gone down significantly after the acute injury. The surgery is called “Annular Ligament Desmotomy“. Without the surgery there is a lot of tension on the tendon where it meets the annular ligament which provokes pain (the annular ligament desmotomy is described in another article).

    I’m curious as to how these racehorses are being maintained. I just accepted a 17.2 4 year old in on race training that sustained a bow back in spring of 2010. I’m wondering the best route to start him back into training and racing and to help reduce the risk of him rebowing. The gelding’s not a very “speedy” horse, just has such a ground covering stride that he wears down the other horses. Any advice?

    Do not race a horse after he has had a bowed tendon. Retire him find him a home as a sporting horse. You are going to permanently lame him. Geez.

  4. I’m do not good exactly where you’re getting your facts, having said that excellent matter. Need to commit a while mastering far more or perhaps finding out more. Thank you outstanding information I’m looking for this info for my mission.

    strong pain and discomfort associated with migraine or tension,
    headache, period pain, toothache, cold and flu symptoms, back or muscular
    pain, arthritis and neuralgia. Many people suffer back pain at one
    point or another through out their lives. It is not necessary to say that a lot of thinking makes people ‘heavy-headed’ bending the spine into a question mark.
