Posted on Tuesday, May 25, 2004 - 11:52 pm: I just had MRI of both front legs today on my 10 yr. old TB to diagnose a 3-week old grade 1 lameness that was originally thought to be an abscess or bruise. It was left front about grade 4 on day one about an hour after running cross country and grade 1 the follwing days while soaked for suspected abscess that was found. Interestingly enough, he jogged grade 3 off in RIGHT front today and sound in left front!The horse was sound (wonderfully sound and active in Eventing) for 8 months prior to this lameness and was only off last summer for a couple weeks which was corrected with good shoeing and thought to be simply sore right front heels. X-rays summer of 2003 and again May 2004 showed nothing irregular. I wanted the MRI to rule out anything else just to be safe because he had not come completely sound... was hoping it was just deep bruising that needed more time to heal though  Diagnosis from today's MRI was: Bilateral navicular synDrOme with injury to both deep digital flexor tendons and potential for adhesions of the DDFT to the navicular bone. There is an injury of medial DDFT in the left front foot this appears to course distally where there is defect in the cortex of the flexor surface of the navicular bone. There is also increased and striated signal from the region of the impar ligament with apparent thickening of the ligament. The right front leg has a lesion in the lateral aspect of the DDFT with damage in the navicular bursa and the tendon at the flexor cortex. I'm waiting on an addendum from the vet once all the images have been evaluated but of course my mind is racing. He would not give any prognosis at this time. The diagnosis does sound pretty terrible in that it sounds to me they found multiple problems. I'm not sure it all FITS with the history of the horse though. He is a 10 mover (long springy strides), competing at Training/Prelim Eventing and the only times we've dealt with lameness in the last 5 years prior to this has been during off season and was contributed to poor shoeing (we have a new farrier since then and he's done wonderfully). Any advice, insight, thoughts... anything would be appreciated. thanks so much |
