"The bony pelvis is formed by the sacrum and coccyx and a pair of hip bones (os coxae or innominate bones), comprising the ischium, pubis and ilium and are part of the appendicular skeleton."
"In childhood, each hip bone consists of three separate bones (ilium, ischium and pubis) connected by the triradiate cartilage. Around puberty, these bones fuse."
