Pelvic Ligaments and Sacroiliac Biomechanics

A refined anatomy chart that bridges structural precision with biomechanical insight.
This chart presents the pelvis as both a mechanical framework and a dynamic system of load transfer, showing how bones, ligaments, and fascial chains stabilise movement through the sacroiliac joints. A truly elegant tool for educating on how imbalance, asymmetry, or ligament strain affects the entire kinetic chain.

Function Section (A–L):
Core biomechanical concepts are mapped directly onto the anatomy with directional arrows — explaining how form closure (ligament fit) and force closure (muscular–fascial tension) maintain pelvic stability. Includes vectors for load transfer, nutation/counternutation, force slings, and compensatory chains across the spine and lower limbs.

Structure Section (1–35):
Each number identifies a key anatomical landmark — from the iliolumbar and sacrotuberous ligaments to the pubic symphysis and coccyx. Accurate, labelled, and clinically aligned for chiropractors, osteopaths, and physiotherapists.

Designed to improve understanding between practitioner and patient.
The chart turns complex pelvic mechanics into clear visual logic — helping clinicians demonstrate load transfer, postural asymmetry, and pain referral patterns with confidence. Patients instantly see how local dysfunctions (e.g. SIJ irritation, pelvic tilt, postpartum strain) connect to whole-body compensation, from lumbar tension to lower-limb imbalance. It bridges the gap between clinical explanation and visual learning — making assessments, treatment plans, and follow-up conversations faster, clearer, and more engaging.

Ideal for:
Chiropractic & Osteopathic Clinics — patient explanation and postural analysis.
Physiotherapy & Sports Medicine — rehabilitation planning and movement retraining.
University Teaching — functional anatomy, biomechanics, and manual therapy.

✓ How this chart supports patient education.
This Pelvic Ligaments and Sacroiliac Biomechanics Chart helps practitioners explain pelvic ligament anatomy, sacroiliac joint mechanics and the relationship between load transfer, pelvic stability and movement control. It gives patients a clear visual reference for understanding the sacrum, ilium, SI joints, major pelvic ligaments, nutation, counternutation and how ligament support contributes to pelvic and lower back function. Useful for explaining pelvic ligaments, sacroiliac joint biomechanics, SI joint anatomy, pelvic stability, load transfer, lower back mechanics and patient education in chiropractic, osteopathy, physiotherapy, orthopaedic, pelvic health and rehabilitation settings.
