perhaps another talk with your vet about what they have found, what a “slipped hip” is
I am obviously not explaining well. I’m a physician so I have a pretty good understanding of the anatomy. Actually, my husband, myself, and our good friend Sharon White, all had pelvis fractures of varying degrees in 2010 from riding accidents (and I had a dislocated right hip as part of that), can you believe it, so I have a bit TOO good an understanding of pelvic fractures…
What they are thinking is that the head of the femur is no longer in the acetabulum which leads them to think there probably was a crack through the acetabulum that they did not see on the initial films. Even knowing the exact anatomy, they could not really give us any more information r/e prognosis (except not good) because this injury is so rare in yearlings. They did feel that nothing could be done surgically to help. Basically, they more or less said, put him down now or wait 2 months and hope…
I have had a bit of the same issue myself. I did have a 6 hour arthroscopic surgery on my hip a year ago, about 6 months after the initial accident. Because I had a posterior dislocation which is quite rare especially in women in their 40s, my ortho guy (who is one of the top hip specialists and draws from all over the US) has been unable to give me any real prognosis except wait and see…
I was hoping someone else out there might be one of the “rare” instances or one of the vets on the forum might have seen a similar case… Really, just grasping at straws…
