I found this information after doing a search on HSG. I have a 9 yr old 15h sorrel QH gelding that I purchased a couple of months ago. About a week after I bought him, my trainer and I took him and another horse on a trail ride for about an hour...just walking. After the ride, we noticed that he was "off" on his left front. Farrier checked his feet and found an abscess. Had the vet come out and he dug down into the hoof and said that it appeared to be an abscess that was already healing. He had me soak the foot and then came back out for a recheck. He had the farrier put front shoes on Cash with a plastic insert which covered the hoof under the shoe. Cash seemed to get better, but not totally. So last Thursday, we had a specialist come out to take a look. When he was doing the flex tests, Cash showed more lameness after flexing of the ankle area. So, he took xrays of that area and told us he would call the next day with his findings. Talked to him the next day. The ankle xrays looked good. So, our next step was to take him into the equine hospital where the dr. is going to try to isolate the area by blocking and then taking more xrays. The appointment was scheduled for this afternoon. We drove all the way down to the equine hospital only to have Cash not show any lameness when the flex test was nor when being lunged. Dr. wanted to still take xrays of an area just below the knee. There was a small area on the xrays that the dr. pointed to and said he couldn't determine if it was an old fracture or a splint. This is where I'm not quite sure exactly what language to use. The explanation as I understand it is that there may have been a splint bone fracture or a tear that is healing well. Dr. suggested 4-6 weeks of not riding and then see how he goes. After reading RickB's information I quoted above, I don't remember feeling a "bump" nor did the dr. point one out to me. How long does an injury like this "normally" take to repair? Is there anything I can do to help it along? Any information would be very much appreciated!!!
