Horsepital Diagnosis for Gait Analysis Problems

[Darkly_Dreaming_Dex]

Our boy who was the subject of my gait analysis posts recently went back for more xrays and a front/coffin joint nerve block yesterday. He was so good for the nerve block needle that went into the joint, waited 5 mins then trotted up sound; waiting another 5 mins didn't change his soundness so it looks like its something in the coffin bone area. Vet is 90% sure its DJD/ arthritis in the coffin bone yet the xrays were clear. (10% chance of being collateral ligament damage but vet feels that is very unlikely)
He started Adequan last night along with a glucosamine supplement the vet gave us. i have magnetic boots to use as well. The vet will come and inject the joint next week but i can't remember which drug. If he doesn't come sound then we will have an MRI done, the vet feels it isn't necessary at this stage. Looking for any else's experience of coffin DJD

as i have plenty of DJD ringbone knowledge

All videos have sound inc worlds loudest fart

so mute if at work, they were taken before the lameness work up at the vets.

I'd get an MRI done rather than waiting. Why does your vet think DJD/ arthritis in the coffin bone if the x rays were clear?
I was in a similar position over a year ago. My boy went lame, nerve blocked sound and problem was localised to coffin joint. X rays showed some spurs and minor changes in the joint so we assumed arthritis. Went down the cortisone injection route. He came sound only to go lame again six months later. An MRI confirmed collateral ligament damage, no arthritis.
My advice would be push for an MRI. Cortisone injections can mask a number of injuries. If he has ligament damage he may come sound from this injection only to go lame again once your insurance has run out. Without an MRI your vet cannot tell you the risk of collateral ligament damage. Remember you only have a year on insurance to claim.

My 20 yr old started stumbling on hacks and - long story cut very short - was diagnosed with bilateral front foot lameness tghat was eventually pinned down to DJD and navicular syndrome in both front feet. Early signs in hind feet too. Steroid injections into both front feet. Vet said even if it worked it might give me a few more months of light riding. But it made no difference and sadly my very very special boy was pts before the quality of his life deteriorated even more. What age is your ned?
