A lateral elbow projection with accurate positioning demonstrates
1)an open elbow joint space.
2)the radial head distal to the coronoid process.
3)the radius superimposing the radial tuberosity.
4)the anterior fat pad.
A) 2 and 3 only
B) 1 and 4 only
C) 1, 3, and 4 only
D) 1, 2, 3, and 4

Question

Quizplus · Accepted Answer

An accurate lateral elbow projection should demonstrate an open elbow joint space (1), the radius superimposing the radial tuberosity (3), and the anterior fat pad (4). The radial head should be slightly proximal to the coronoid process (not distal), so statement 2 is incorrect. Therefore, the best choice is C, which includes statements 1, 3, and 4 only.
