My 20 yr old gelding has a bump on his back. He has had it since we bought him in Nov. Vet felt it was congential and shoud be evaluated by a chiro. Chiro thought is congental also and that it was a rotated vertebra. She recommend exercises to strengthen his topline. He went lame just after we got him. Ultrasound diagonosed a tear in his inferior check ligament. He was rested for 2 months and then slowly started back to work by hand walking for increasing time. At this point his back end looked stiff and vet flexed and xrayed and felt that his right hock had arthritis. Now that his ligament is healed enough for undersaddle work we decided to have his hocks injected. That was done 2 weeks ago. He is moving better but still is short in the back sometimes. We have decided that it is unfair to ask him to be ridden as hard and as often as my daughter wants to ride so we are in the process of finding him a light riding home. We had a prospective person come out tonight. She said that she had decades of horse ownership and had owned racehorses for decades also. I told her his whole story as we were walking to his stall. She took one look at him and said that the bump on his back was the problem. That she had many racehorses that had the same thing and that they injected iodine into the muscle along the back to fix it. She then pressed down with her finger tips on the top of his hip and he about fell down. She said that was a sign of pain. She gave me the name of a couple of vets she used for her racehorses. I want to know if pressing down on the hip is an accurate way to tell if a horse is hurtng or can you get false positives? Also has anyone had bumps like this and what did you do? Did they cause problems? Can they be fixed?
