WT BEARING AP

because it shows what they are actually experiencing in their knee when they are standing

Question 29

How do you know if a film is wt bearing

Answer 29

for evaluating scaphoid fx
requires hand to be ulnar deviated

it extends the scaphoid - so you’re looking perpendicular to axis of scaphoid

Question 38

Answer 38

ulnar deviation extends scaphoid

radial deviaiton flexes scaphoid
