What is an innominate?
Innominate, means without a name. The pelvic ring is composed of three bones, the sacrum in the back and two large pelvic bones on each side called innominate bones. Some people refer to them as hip bones, but this is incorrect. If you fracture a hip, you fracture the surgical neck of the femur not the innominate. The prominate crests above your hips are the crests of the ilia which is part of the innominate.
