Basic Patient Position
The patient sits alongside the end of the table with the
affected arm fully extended and the hand supinated, the table
top should be raised to the level of the lower border of the axilla
so the whole arm is supported and parallel to the cassette. The
patient should lean externally to bring the humeral epicondyles equidistant
from the film, in this position the wrist will be externally
rotated from AP.

Radiation protection
Direct lead rubber gonad protection using a "half
apron".
Ensure the lower limbs and torso are not below the table top in
the primary beam.
|
Central Ray
The vertical central ray is centered midway between the skin
surfaces to the joint space which is approximately 3 cm below a
line bisecting the humeral epicondyles. The long axis if the arm
should be in line with the long axis of the tube.

Evaluation of the Image
ID and markers must be present and correct in the appropriate
area of the film
Limits of the examination, superiorly distal 10 cm humerus,
inferiorly proximal 10 cm forearm. laterally the skin surfaces.
Evidence of collimation on four sides equally around the centering
point.
The open joint space should be visible.
The medial quarter of the radial head will be superimposed on
the ulna.
