Q

How can you differentiate between M & F pelvises?

A

(3) Sacral promontory - sticks out more in M

(4) Ischeal spines - stick out further into the pelvis spines in M

(5). M - pelvis thicker and heavier, with deeper greater and lesser pelvis spaces.

(6) Pelvic outlet - bigger and wider in F

(7) Obturator foramen - round in M, oval in F
