Key takeaways:
- The sacroiliac joint is not responsible for flexion. That is the job of the lumbosacral joint. The SI joint takes on the shearing forces transferred up from the hind limb. It moves in a side to side action, not a hinge action.
-The SI joint acts like the shocks in your car. It absorbs concussive force. A sprung or collapsed pelvis is like blowing your shocks. The forces exerted from the hind leg, no longer absorbed by the SI and pelvis, will now be transferred to the lumbar spine. And so begins lordosis/ ITP crowding/ overriding/ roached lumbar.
-Once the pelvis has sprung or collapsed, the p***c symphysis fuses, the SI creates bone spurs and arthritis sets in.
-There is no undoing this. This is permanent. No injection, no bodywork, nothing is restoring the pelvis to healthy function.
Becks doesn't even begin to describe implications to the distal limb. A collapsed pelvis changes the whole orientation of the acetabulum to the greater trochanter (hip joint or pelvic connection to femur bone). That changes the orientation to the stifle... That changes the orientation to the hock.... You get where I'm going with this.
This was not supposed to be a post about the efficacy and ethics of injections. I've seen injections cause a great deal of relief for many horses. I've seen them do absolutely squat, and I've seen them destabilize a horse to the point of no return.
But it scratches at the back of my brain, this game of whackamole. Inject a stifle here, a lumbar vertebrae there, while something as noxious as a collapsed pelvis continues to ooze dysfunction all over the body, indefinitely.
I am so incredibly grateful to the equine sciences collective that continues to mine for answers. I look forward to the day when I can attend a whole horse dissection. Until then, I'll keep watching for those blinks and yawns š
