Study Notes
Anatomy of Pelvic Inlet and Outlet
- The red line is the accurate line, the bony boundary of the ilium.
- The blue line is the back to it line, associated with the superior ramus of the pubic bone.
- The pelvic inlet is formed by the sacral promontory, wing of the sacrum, accurate line of the ilium, back to it line of the pubic bone, and the pubic crest and symphysis.
- The pelvic outlet is formed by the coccyx, sacral tuberous ligament, pubic arch, and part of the pubic symphysis.
- The pelvic girdle's articulation is crucial for weight transfer and energy resistance.
- Three important ligaments are sacroiliac, sacrospinous, and sacrotuberous, stabilizing the pelvic girdle.
- The sacroiliac ligament stabilizes the joint between the sacrum and ilium.
- The sacrospinous ligament stabilizes the joint between the sacrum and ischial spine.
- The sacrotuberous ligament stabilizes the joint between the sacrum and ischial tuberosity.
- The sacroiliac, sacrospinous, and sacrotuberous ligaments ensure pelvic girdle stability.
- The sacrospinous and sacrotuberous ligaments divide the space into two foramina, through which structures can pass.
- The foramina are openings through which different structures can pass.
