State the degree of central ray angulation that should be used for an ulnar-deviated PA axial (scaphoid) wrist projection being obtained to demonstrate a proximal scaphoid fracture.
a. Use a 10-degree angle if the first metacarpal and ulna are aligned.
b. Use a 25-degree angle if the first metacarpal and ulna are not aligned.
c. Use a 15-degree angle if the first metacarpal and ulna are aligned.
d. Use a 20-degree angle if the first metacarpal and ulna are not aligned.
Question 2
A less than optimal lateral wrist projection demonstrating the distal scaphoid anterior to the pisi-form
a. will also demonstrate the distal scaphoid proximal to the pisiform.
b. will also demonstrate the ulna anterior to the radius.
c. was obtained with the wrist in ulnar flexion.
d. was obtained with the wrist internally rotated.
