Document Summary
Transmitted force: pelvis is designed in order to transmit weight from body through our femur to the ground, as weight is transmitted centrally through vertebral column, it is equally divided across si joint and pelvis. Female pelvic girdle (more info on page 331 of textbook) Located between l5 and s1: made up of 2 joints: Intervertebral joint: between l5 and s1 last iv disc in vertebral column. Superior-facing s1 facet joint: faces anterior and slightly lateral. Facet joint is more anterior-posterior than medial-lateral faces posterior and slightly medial: different than lumbar facets. Iliolumbar ligament: runs form tp l5 to iliac crest: important because it helps prevent l5, which naturally wants to slide forward, from translating anteriorly off of s1, prevents anterior translation of l5. Important in terms of interlocking to prevent movement: si joint is 2 joints, anterior facing joint: plane joint.
