Pelvic Girdle Bones (Pelvis and Hip)

Acetabulum

Formed by the 3 ox coxae bones, this is where the femur articulates to form the hip joint.

os coxae

Hip bone. Has one of the few ball and socket joins with synovial fluid. Composed of the ilium, ischium, pubis bones. Features include the acetabulum, pubic symphasis, ischial tuberosity, obturator foramen, iliac crest.

Pubic symphasis

Joint - fibrocartilaginous - where the 2 pubis bones meet

ischial tuberosity

Located on the superior ramus of the ischium bone. Is the "sitting" bone.

Ischium Bone

Most distal bone of the ox coxae, forms the back of the ox coxae and is made up of the superior and inferior rami.

Ilium Bone

Most proximal, largest bone of the os coxae

obturator foramen

The foramen created by the ischium and pubis bones through which nerves and muscles pass.

Pubis Bone

The medial and anteriorly facing bone of the the ox coxae. Makes up 1/5 of the acetabulum

iliac crest

The superior boarder of the ilium.
