Bone bruises can take some time.
Did the MRI show anything else? I ask bc you said you injected coffins and NB.
My horse stepped on a rock at a show a year ago May. We thought he was just footsore at first at the show bc it resolved with packing his feet. Did MRI ultimately that showed bone bruise, collateral ligament damage, and something strange looking with the DDFT, all lining up to the divot on his foot from the rock. Treated all threeāOsPhos for bone, coffin joint injection with ACS for CL/DDFT. Thought was that heād come sound sooner, rather than later, if it wasnāt the DDFT. Which he did, though it was 5-6 months from the time to injury to when he was back in full work. Started feeling funky in March when we were dealing with non-stellar footing due to rain plus Covid. Ultimately did another MRI that showed pretty much the same things as before, but now the DDFT was specifically in the navicular bursa area. All described as mild and both vets seemed to think āno big deal.ā At beginning of June repeated OsPhos, injected coffin joints and NB with ACS because I still had some left over. Vet seriously thought horse would be fully back to work by now. Horse felt amazing when we started back to work, but deteriorated. Did shoeing rads and now shod to keep medial-lateral balance better. Sound on lunge, off under saddle. Two weeks ago re-injected NB with PRP which is vetās usual go-to for this. Instructions are to tack walk for two weeks and see what we have. That will put us at the end of September, which would give us 2 or so decent months to bring him back into work if heās sound. Iām not convinced what I will do either way: will probably depend somewhat on whatās going on with feet/angles at that point.
My vet is a big believer in movement and that tack walking is generally OK in situations where hand walking is an option. Depends on the sanity of the horse and the ability to find someone willing to sit on the horse and walk it. So mine gets tack walked by me 30 or so minutes five days a week and hand walked by the barn twice on the days I donāt ride and an additional time on three of the days I also tack walk. Otherwise, heās in a stall.
