Answer 10

8 -14

Question 11

what does anterversion mean

Answer 11

increased torsional angle

Question 12

what does retroversion mean

Answer 12

decrease torsional angle

Question 13

are the toes pointing in or out with anteversion

Answer 13

toes in

this is a better position for the femoral head
