Question:
I had an MRI and was told my horse had a tendon tear in the foot. What do I do?
Answer:
The deep digital flexor tendon originates as a muscle attaching in the forearm area, turns into tendon as it crosses the back of the knee, runs over the “flexor surface” of the navicular bone, and inserts onto the bottom of the coffin bone. If an MRI was required to diagnose the tendon injury in your horse, then the damaged portion of it lies within the hoof itself. DDF injuries observed on MRI scans are commonly found just above or at the level of the navicular bone, and fresh tears are essentially a “bowed tendon” inside of the foot. In the later stages of healing, gradual return to exercise to strengthen the tendon is a vital part of the rehabilitation process. Extra-corporeal shockwave therapy, and injection of the deep digital flexor tendon sheath and navicular bursa with lubricants are additional therapies than can be applied to enhance the healing process. Unfortunately, there is no bandage or wrap that can support this area. The best strategy is to have her feet well balanced and trim at regular intervals to prevent excess tension on the tendon.
