How's things in Nevada?
Hunters Bump. This is a sub luxation of the sacrum, which is milder than a
dislocation. It can be treated with Chiropratic, after the cause is rmoved.
In my practice both human and equine I encounter this quite a bit. I usually
find a hypertonicity in the hamstrings, which attach to the sacrum, and the
lumbar fascia.
For me, the question is: "why does the horse have tight hamstrings". I "see"
the tight hamstrings as being either occupational, Jumping, Cutting, or
structural Pushing into closed shoulders, heavy on the forehand, or resulting
from an injury, slipping.
In the human a subluxated sacrum can cause irritation to the sciatic nerve,
as the piriformis spasms, with pain down back of the leg as well as in the
quadraceps area.
The Bump can also be caused by a rotation of the illia, unilaterally either
dorsally or ventrally.
My suggestion is to have the horse evaluated by a Vet that can do Chiro. the
cause needs to be understood and rectified. Assure it is a subluxation and
not dislocated, this would be very extreme to me. The bump is not the cause.
Find someone to open the hamstrings, to allow the adjustment to hold. Keep
the horse stretched well, especially the hams and shoulders.
The fact that it is in the horses brothers? only tells me that they have a
conformational pre-disposition to it.
good luck
