The hip bone (os coxae) is the complex-shaped bony structure formed after the fusion (synostosis) of three bones: ilium, ischium, and the pubis, that usually occurs before the age of 20*. The two hip bones are the major structural component of the pelvis.
Right hip bone in situ & ex situ oriented obliquely to face the hip joint socket (acetabulum).
Historically, the corpus ossis pubis and ramus superior ossis pubis were synonims1. Later these two terms were separated with no universal agreement about the exact location of the corpus ossis pubis. Many respected anatomy atlases2,3 place the body of the pubis within the acetabular region. That localization does not match the official anatomical terminology, according to which the body of the pubis contains the tuberculum pubicum, facies symphysialis, and crista pubica4. This statement is in agreement with the image above and other anatomy textbooks based on International Nomenclature.5,6.
