Posted on Sunday, Aug 13, 2006 - 1:03 am: Dr. O.,I just purchased a 7yr. old imported Dutch WB. He is relatively talented and has been pushed hard for his age - already doing tempis and pirouettes etc. I was lucky/crazy enough that about 4 months ago when he was vetted for another family he failed to pass his vet check, he has sat around ever since until the seller DrOpped the price drastically and I decided to buy a lame horse. The horse trader had him x-rayed, bone scanned and MRI’d four months ago at the first sale. He was/is slightly (1 out of 5) off on his right front (about every 6th step) on hard ground on a circle. It is not at all apparent under saddle or in a straight line and he has been continued in hard work until I bought him two weeks ago (since then he has been on stall rest and hand-walking). His flexions were a little rough on both front feet but he trotted out of it in about four steps. I have his original x-rays from Holland about 9 months ago & the new x-rays from four months ago. They all look fine according to all of the vets (3 sets of eyes) – nothing shows up at all. That said, I did upload one of the Holland images (they should have pulled the shoes!). What do you think? Nothing showed up in the bone scan either. It is so small an “offness” that blocking wasn’t advised (is this true? Should I still try some blocking?). On the MRI (jeez these are expensive) there was a little bit of uptake in what the vet has decided was the collateral ligament of the foot. Basically I’m posting for three reasons: 1. Do you believe that the collateral ligament in his foot could be the correct diagnosis…From reading your site I don’t hear much mention of the collateral ligaments in the foot so I’ve begun to wonder if all of the vets are talking about different parts of the anatomy and using inappropriate terminology (or maybe it is just me) if it were the collateral cartilage it should show in the x-rays, correct? If it was navicular it should also show in the x-rays, right? His front feet are huge – they look like he paddled across the Atlantic by himself, his back hooves are much more “American” looking. The horsetrader I purchased him from claims the farrier tried to trim him down into our version of hooves and this was the result. I think she specializes in telling buyers what they want to hear. His confirmation seems to be fine and he is an excellent mover although they were riding him very on the forehand. 2. Is there anything else that this could be that I need to research? We don’t have a 100% diagnosis as the test were relatively inconclusive. 3. The second set of vets advised only 4-6 weeks off and 3 shockwave treatments. I’ve already given him two weeks off, we are planning to shockwave this week (unless you think we are nuts… this is one of those “try everything plus the kitchen sink” things). Then after reading on your site and others I’m planning to give him at least 3 weeks after the final week of shockwave. That would mean he would get a total of 8 weeks off and then I’m thinking another 30 days of walking under saddle gradually adding a little trot work for another 30 days after that. Does this seem reasonable? Any feedback? I really appreciate it! Kate P. |

Posted on Sunday, Aug 13, 2006 - 4:56 pm: Kate, I am confused is it the collateral cartilage that is thought to be a problem or the collateral ligament. These are 2 different structures of the foot. We have an article on collateral cartilages at Diseases of Horses » Lameness » Diseases of the Hoof » Sidebone and the Collateral Cartilages. The collateral ligaments are what hold the joints together. First let's be sure of what is being diagnosed but in either case, "a little bit of uptake" sounds like a hedged bet and may not be significant.DrO |

Posted on Sunday, Aug 13, 2006 - 8:55 pm: Dr. O,Thanks for your response. I'm confused too! Basically the vets can't see anything on x-rays or bone scan, but maybe a little something in the MRI. I was hoping that you would say, "of course you would see ringbone or sidebone or navicular on the x-ray/bone scan, so all that leaves is the collateral ligament". I had hoped that "uptake" in the horse's foot would lead to a specific diagnosis, but the collateral ligament idea does seem like a hedging of bets. What other diagnostic test could I do? He has been slightly off, but serviceably sound for the past four months and in hard work with the seller. They injected his coffin bone when they were trying to sell him for mucho dinero, and supposedly it made no difference. I want to give it the best try at getting him sound. If I shockwave him assuming it is the collateral ligament in his foot, is there a chance that it could cause the collateral cartilage to start solidifying (which wouldn't be good). Or is ESWT a decent option? Should I plan to give him at least three weeks off after the last treatment? Then I plan to rehab him very slowly following the tendon rehab article (but without a ultrasoundable lesion it makes it a lot more guessing!) He has had the last two weeks off on stall rest with hand walking... since he is only lame on hard ground on a circle to the right when is it okay to lunge him to check it out. I don't want to lunge him just to see if he is still lame only to set us back again (kind of like checking to see if bread is rising!). Thanks, Kate P. |

Posted on Monday, Aug 14, 2006 - 10:31 am: Neither the collateral ligament or the cartilages are visible on the radiograph, I am afraid. Being soft tissue structures they are not easily visualized in the foot.Check out the article Diseases of Horses » Lameness » Diseases of the Hoof » Overview of Diagnosis and Diseases of the Foot. It gives you a step by step plan on diagnosis of diseases of the foot including collateral ligament desmitis. DrO |
