Overview

The pelvic girdle is the point of attachment for the thigh of the lower limb (femur). The pelivc girdles consist of three bones that join together to form the os coxae. The three bones are the ilium, icshium and pubis. The area where the three bones join together form a hollow cavity called the acetabulum; which is the point of attachment for the head of the femur.

The pelvis is a combination of bones. It is comprised of the two os coxae, or coxal bones, joined posteriorly by the sacrum and anteriorly by a piece of fibrocartilage called the pubic symphysis. The pelvis forms unique landmarks that are not found on the pelvic girdles so make sure you know the differences between the two.
