Study Notes
Pelvis
- Each innominate (pelvic bone) is formed by the union of three bones: ilium, pubis, and ischium.
- The innominate bones connect at the pubic symphysis (anteriorly) and the sacrum (posteriorly) at the SI joint.
Function of the Pelvis
- The pelvis serves as a common attachment point for various muscles.
- It transmits the weight of the upper body and trunk to the:
- Ischial tuberosities during sitting.
- Lower extremities during standing and walking.
- The pelvis supports organs involved in:
- Bowel functions.
- Bladder functions.
- Reproductive functions.
Femoral Shaft and Neck Angles
- The angle between the femoral neck and shaft in the frontal plane is:
- Normal: around 15°.
- Anteversion: more than 15°.
- Retroversion: less than 15°.
- The angles are described in relation to the anterior and posterior positions.
