Indications for imaging
Injury to the elbow in cases of suspected supra condylar
fracture with the patients elbow is presented in flexion, to
prevent further injury in these cases the elbow should not be
extended .

Anatomy Demonstrated
This projection demonstrates the distal humerus and olecranon
process of ulnar.

Basic Patient Position
From the AP position the patients elbow is flexed maximally,
ensure that the humeral epicondyles are equidistant to the film.

Radiation protection
Direct lead rubber gonad protection using a "half
apron".
Ensure the lower li8mbs and torso are not below the table top in
the primary beam.

Central Ray
The vertical central ray is centered 5 cm distally along the
forearm at 90 degrees to the humerus

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
Evidence of collimation on four sides equally around the centering
point.
the humeral epicondyles and the olecranon process should be
projected in profile.
Penetration should be increased to demonstrate the trabecular of
the superimposed humerus, radius and ulnar.
