I know, I know, it's another blog post about the pelvic girdle. Well, sort of. Sometimes it's a thankless job, holding the weight of our upper half, so this post is going to be dedicated to my favorite pair of jutting wings—the hip bones!

Did you know? The hip bones are part of the appendicular skeleton, which also includes the shoulder girdle and the upper and lower limbs.
