The Anterior-Inferior Sacrum Subluxation

"The sacrum is the foundation of the spine. When it subluxates anteriorly and inferiorly, nothing above it sits right — and the body spends enormous energy compensating." — Dr. Romar Rochet

What the AI sacrum is

The anterior-inferior (AI) sacrum is a specific subluxation in which the sacrum — the base bone of the spine — tilts forward and downward. It's one of the most structurally significant subluxations Dr. Rochet corrects. Not because of where it is, but because of what it does to everything above it.

Why it's so disruptive

The spine is a mechanical column. Every vertebral segment above the sacrum depends on that foundation being level. When the sacrum subluxates anteriorly and inferiorly, it tilts the platform the entire lumbar spine sits on. The lumbar curve compensates. The thoracic curve compensates. The cervical spine compensates last — and it often takes the most stress.

The correction

Dr. Rochet corrects the AI sacrum subluxation with a specific sacral adjustment that addresses the displacement direction. The foundation is reset. As the sacrum returns to its correct position, the compensatory stress in the segments above begins to release. Correction starts at the base.

What happens with correction

Patients with undetected AI sacrum subluxations often present with complaints that seem unrelated — neck pain, hip problems, knee tracking issues, respiratory changes. The correction addresses the cause. The complaints that followed the structural disruption often follow it back.
