Indications for imaging
  • Trauma - dislocations, fractures, soft tissue calcifications
  • Arthritis survey
  • Bone pain.

Humerus AP positioning

Basic Patient Position

The patient stands erect AP, the position of the film is adjusted to included the shoulder and elbow joints. The patients arm is abducted approximately 20 degrees and externally rotated to bring  the distal epicondyles equidistant from the film, the patient may need to be rotated to the affected side. The humerus may need to be positioned diagonally across the film to included the full length.

Central RayThe horizontal central ray is centered midway between the skin surfaces at the midpoint of the humerus. Exposure is made on suspended expiration.

Humerus lateral positioning


Basic Patient PositionThe patient stands erect PA, the position of the film is adjusted to included the shoulder and elbow joints, with the humerus in contact with the cassette, i.e. rotated into the anterior oblique position approximately 20 degrees. The arm is abducted approximately 35 degrees away from the trunk and the palm of the hand placed on the iliac crest to bring an imaginary line through distal humeral epicondyles at 90 degrees to the film, elbow in true lateral position.
The humerus may need to be positioned diagonally across the film to included the full length.


Central RayThe horizontal central ray is centered midway between the skin surfaces at the midpoint of the humerus. Exposure is made on suspended expiration.
