"Innominate" is not a combination of any specific anatomical structures.The term "innominate" is typically used to refer to the hip bone or the pelvic bone. It is a large, irregularly shaped bone that forms part of the pelvis. The hip bone consists of three fused bones: the ilium, ischium, and pubis.
