Rey Bustos’ Propeller Pelvis

Filed under: Anatomy, Rey Bustos — Anya Galkina - Studio Mysteries @ 6:08 pm

Did you know that the pelvis has a propeller structure? Bet you didn’t know that. Propeller structure, in engineering terms, means a plank that has been twisted, so that one part of it is at an angle to the other.

The bones of the pelvis are twisted just like that! The upper pelvic bones (the ilium), are at an angle to the lower pelvic bones (the pubis). Check it out:


See the direction in which Rey’s fingers are pointing? That is the angle of the ilium planes.


Now see the picture below – the pubic plane is a totally different direction:


See? It’s a propeller plank!

This is why anatomy is impossible to learn purely from books. You need a teacher with a passion for the subject and a good sense of humour.

P.S. That is a very understanding pelvis, especially considering it used to belong to a dude. As Leonard Cohen says, we are so lightly here.


  1. Who knew? I’m a Leonard Cohen fan too.
