Ridecamp: Re: [RC] hunter bumps (was Sore Backs)

>From what I was taught/read, you can also have a pretty pointy croup just as
part of conformation, but a hunter bump looks a little different, especially
a severe one.  If it is a hunter bump, it doesn't necessarily have to be the
result of overriding.  I'm positive Dakota pulled his just goofing around in
pasture with his buddies.  And it's not muscle injury.  The upper part of
the pelvis is called the ilium and the lateral points of that are what form
the points of the hip.  Right underneath that is a chunk of fused vertebra
called the sacrum.  If a horse is really thin, this is part of what forms
the bony ridge over that part of the topline.  Between the ilium and the
sacrum is an immovable joint with ligaments attaching and stabilizing the
two together.  If these ligaments are injured, then the attachment between
the two destabilizes and upper portion of the pelvis (the tuber sacrale)
moves upwards and forward to form the hunter bump.

There are a lot of horses that have them, mostly in horses that use a long
forward stride in doing whatever they do (in Dakota's case, being a dork in
pasture).  There was a study that said harness horses returned to racing
after one of these injuries earned less money, but there are a lot of other
things that might have contributed to that as well.  Certainly any joint
(although the sacroiliac is not a true joint, just an attachment)
post-injury is weaker than the original joint, but it's not a death sentence
or anything, obviously.
