Ok, we have a diagnosis and MRI result. Both feet were imaged in TAMUs 3 Tesla MRI under general anesthesia. The whole experience was amazing and I am very grateful to TAMU vet school for the way they treated me and my horse. So - in his right front foot only, he has Navicular Bursitis with Fibrotic lesions. Treatment is surgery to remove and clean out the lesions, and TPA (Tissue Plasminogen Activator) to prevent further fibrosis/lesions. Then 2 weeks stall rest with 4x daily hand walking, moving to 24 hr turnout in a small area with progressive exercise over 2/3 months. And correct trimming and shoeing to get and keep his feet in shape.
The intake process at TAMU was so cool. Everyone was incredibly kind and careful and thorough. My horse stood quietly and was at ease with them. We had vet techs, vet students, at least two vets, and a farrier observing/checking/palpating/testing my horse from head to toe, taking his history, etc. When the moment came to say “goodbye” and leave my horse in their hands (his MRI was the following morning) one of the vets was so reassuring and confidence-inspiring that I had no trouble leaving (once I got home was another story
But that’s what large bottles of wine are for, right?)
They called me at work the next day when he came out of anesthesia - I was so worried I remember just sitting at my desk trying to hold it together. Seriously, when they said “he’s up and hanging out in his recovery stall and did great” I almost stood on my desk and held my phone in the air and yelled “HE SURVIVED!!!” I got two more long calls later that day to talk about the results and treatment options. Some if it is a blur as I was super emotional and worn out (partly from relief). I took lots of notes on about 7 scraps of paper - mostly illegible, but I’ll get full formal report Monday. They emailed me the link to his MRI images.
So, his other structures in the hoof look fine. They said the navicular bursitis is a fairly common problem, but the fibrous material is more rare. They say it is a reaction to inflammation, and once it starts up, it tends to be self-perpetuating until the lesions are removed and cleaned up. They mentioned there may be a hereditary component to this type of reaction to inflammation, but they are not sure. It is definitely a reaction to trauma of some sort - could be hoof balance issues, or could be one time trauma (which they suspect, given the other foot looks fine). All we can do is treat, and then address all known issues (like getting his feet trimmed correctly).
The treatment is arthroscopic surgery to remove and clean up the lesions - and during surgery, he’ll receive Tissue Plasminogen Activator (TPA) in the foot to discourage more fibrosis or adhesion formation. They will treat him again in 3 days with the TPA. Total stay at TAMU is about a week from the surgery date - then he can come home for a short period of stall rest with hand walking 4x a day, followed by 24 hour turnout in a small area (30 x 30ish) and we can start a schedule of very slow progressive exercise for approximately 2/3 months to bring him back into work. The turnout and careful movement is important to prevent adhesions during healing.
They said that we caught this early - they usually see horses that have had this “brewing” a year or two (while other treatments were tried). By then, the fibrous tissue is a solid hard mass, and prognosis is poor. They mentioned several times that we are lucky it was caught early.
TAMU is a couple of hours away. I woke up early and drove out to visit him today. It was so good to see his beautiful face. He was happy to see me - he is a goofy horse and I swear he was trying to be extra cute and funny today. Took him out to walk him and hand graze him about an hour. I will go back in the morning to spend time with him. It was such a relief to see him. I feel a little crazy right now. I wish he weren’t so “real” to me as a thinking, feeling creature who has been dropped off in a strange place with none of his horse friends, or barn people he knows, or me.
However, he is being very well cared for and is in a safe place - they constantly check on him, groom him once a day, he gets a little turnout time, etc.
So, he has a diagnosis and a treatment plan. I also have a new farrier who is on board with working to get his feet sorted out once he’s home. There is risk to the surgery and treatments, and there’s risk something will go wrong in rehab, or that his body won’t respond properly, but I feel hugely relieved.
I’ll check back in to let you know how things go!
