Is the hip-bone a legal target for a punch?

The scoring area is from the waist line up, on the front of the torso and head, not the top of the shorts, otherwise Lennox Lewis's waist line was just under his tits!

You'd risk breaking your wrist by purposefully hitting it.

Gatti broke his hand in the third fight with Ward hitting him on the hip.

Foreman used that punch generously. That weird "amateurish" right he would throw that either bluntly exploded on the hip joint or barely made it another inch around and thudded into the kidney. OUCH.
