The Pelvic GirdleHipbones – Innominate Bone• Made up of 3 fused bones:

– ilium – ischium– pubis

• Acetabulum - hip socket– meeting point of ilium,

ischium, & pubis – on the lateral surface of the

Innominate articulates with head of femur

The Pelvis• Consists of 2 innominate bones, sacrum, & coccyx

Childbearing Modifications• Enlarged pelvic outlet• Broad pubic angle (> 100°)• Less curvature of sacrum and coccyx• Wide, circular pelvic inlet
