Had a horse diagnosed yesterday with a proximal (superior) check ligament tear. Apparently this is not as a common an injury as the distal check ligament. I can supply ultrasound and radio graphs, but Colo State Vet School is recommending 8-10 weeks rest, then looking at IRAP or stem cell injections, neither being cheap but also not prohibitive in the $1000-$2000 range. Does anyone have experience with either the injury or the treatments?
