Bowed Tendons in Horses

Sharing is caring!

One of the most dreaded injuries a sport horse can incur is a bowed tendons in horses.  Sport horse owners dread the day when the vet gives their horse this diagnosis.  Questions immediately follow: can it be fixed? Will my horse show again? And the answer, as always, is that it depends.

Bowed tendon injuries used to mean the end of a horse’s career.  But, with today’s more advanced technologies and veterinary research, it is possible for horses to recover from bowed tendons.  But, it is still a difficult process, and it is one that you must take with both your horse and your vet by your side.

In this article, I’ll be discussing what bowed tendons are, what causes them, how to treat them, what recovery from bowed tendons can look like, and how to prevent bowed tendons. 

What is a Bowed Tendon?

According to the American Association for Equine Practitioners, a bowed tendon is when a horse has suffered, “the tearing of the superficial digital flexor tendon in the middle of the cannon bone region. This tear causes a curved, bow-like swelling on the back of the leg between the knee and the ankle. Although the swelling is usually in the middle of the cannon bone, it may be behind the knee, at the level of the ankle, or it may extend from the knee to the pastern.”

What is a Bowed Tendon?

It is similar to a person tearing an ACL, MCL, or meniscus in their knee.  The pain is severe, and the recovery process can be long and trying. 

Causes of Bowed Tendons

While there are certain types of horses and certain disciplines that statistically produce more bowed tendons, every horse participating in any type of physical activity is at risk of a bowed tendon.  The same way that football players and cross country runners are statistically more likely to tear their ACL than I am while taking my dog for a walk.

Bowed tendons can occur suddenly during exercise, and they can gradually build up over time.  The causes of bowed tendons come down to over-exertion and flexion in that tendon

For example, if a showjumper stretches too far to clear an oxer out of a long-distance, and then lands (therefore applying pressure) the already stretched tendon, this could cause a bowed tendon.

Or, a racehorse that runs the same track, in the same direction, every day, could develop a bowed tendon from over-exerting the same leg and tendons around the corners every day.

Treatment for Bowed Tendons

Similar to many equine injuries and illnesses, there is no magic cure that will make a bowed tendon go back to normal.  In fact, a bowed tendon will never go back to normal. Once it has been stretched, it will never retain its original size and shape.

But, there are ways to treat bowed tendons to help your horse become comfortable after his injury, though your horse may not like these methods.  The best thing you can do for a horse with a bowed tendon is to let him rest.  

This means no exercise, no turnout, barely even hand-walking.  Horses with bowed tendons need to be put on stall rest for a long amount of time, to allow the tendon to try to heal itself.  From there, your vet will develop a rehabilitation plan with you, for your horse.

These rehabilitation plans look like lots of hand walking in small increments, slowly, over months and months, building up to maybe a few minutes of trot work.  Then again in a few months, maybe some canter work.

It can take over a year for a horse to fully come back from a bowed tendon if it is possible for them to come back at all.

Recovery from Bowed Tendons- Is It Possible?

Thankfully, it is possible for a horse to recover from a bowed tendon.  But let me be very clear- it won’t happen in every case.  Sometimes horses will not be sound again after sustaining a bowed tendon.

Sometimes, the horse will come back from rehabilitation sound, but unable to compete at the level they were once able to.  These horses may need a career change, or even just a lower level to compete at.

Miraculously in this day and age, sometimes horses will make a full recovery! It is possible, thanks to technology and advanced veterinary research, that a horse that sustains a bowed tendon can make a full recovery, and resume competing at the same level he was when he sustained the injury.

Preventing Bowed Tendons

Bowed tendons are scary, and although it is possible, there is no promise that they can be completely healed. We all want what is best for our four-legged partners, and as such, there are some preventative measures that we can take in order to protect our horses from bowed tendons.

First, monitor and adjust your sport horses’ training program.  Every horse is different and can handle different things.  But make sure you aren’t doing the same thing every day. Shake things up, make some days harder than others, etc.

Preventing Bowed Tendons

Even Olympic level show jumpers don’t need to jump every day.  In fact, these horses frequently only jump once or twice a week.  And, they only jump “to height” (i.e.- the height they jump in the show ring) right before they go to shows.  Olympic riders know that they have to save their horse’s legs if they want to have successful careers.

Second, use protective “tendon boots” on your horse.  All disciplines of sport horses (eventers, show jumpers, dressage horses, racehorses, reiners, barrel racers, etc.) can be seen wearing polo wraps, splint boots, and other protective boots on their legs, between their canon bone and their fetlock.  

These boots can help give horses extra support in these areas of their legs, preventing some of the physical impact and strain from being inflicted on their tendons and muscles.

Conclusion

Bowed tendons can be very scary.  Thankfully today, horses can recover from them, and there are things that can be done to prevent them.  I hope this article helped you learn more about bowed tendons in horses! If so, please share it, and share with us your experiences dealing with bowed tendons!
