thank you for your presentation I start my interest in SIJ pain & it is very helpful information in this prisentation

vertical hypermobility. Interesting that the CT images seem to reveal rather planar joint configurations which would be less stable, less form closure than those typical with more convoluted shape, if of course, this level of the joint is representative of the entire joint at all levels. I had to read these studies several times and hear various presentations before the deeper implications were manifested. Gratefully, Jerry Hesch, Hesch Instructor, Hesch Institute, sacroiliac clinician.

The axis of rotation appears to be Illi's ligament/axial ligament of the interosseous ligament complex, which has less collagen than the surrounding ligaments and occupies 14% of the surface area per Bechtel's research. Sturreson, Vleeming and Selvik's landmark research needs to be integrated in the clinical realm. It is fundamental, relevant, insightful. Same for Murakami's injection study. The force closure frame is in the transverse plane though some may have.. to be continued...

Yes, pain in sacroiliac joint area. But no mention about why. Most patients with misplaced SI joint have no pain in SI area to find by provocation tests. They have hip pain, back pain, knee pain, muscle tension where ever, etc. It is the same as spinal facet locks/rib joint misplacement. It is a malfunction of a joint that causes pain locally but also elsewhere. This is what I have learned as a patient suffering SIJ upslip and resulting spinal "locking" problem.
