The innominate is made up of three bones which fuse late during the adolescent phase, including the ilium, ischium, and pubis. The bones fuse together at the center of the acetabulum, the fossa in which the femur articulates, each making up part of the articulation.

## Ilium

Iliac crest, Greater sciatic notch, Lesser sciatic notch, Iliac tuberosity, Preauricular sulcus, Auricular surface, Iliac fossa, and Anterior superior and inferior spines

## Ischium

Ischial tuberosity

## Pubis

Pubic symphyses

Structures formed by the intersection of the three bones of the innominate:

## Acetabulum

Lunate face and Fossa
