1.Antero-posterior
Position of the Patient and Cassette
• The patient is seated alongside the table, with the affected
side nearest to the table.
• The arm is abducted and the elbow joint is fully extended,
with the supinated forearm resting on the table.
• The shoulder is lowered to the same level as the elbow
joint.
• The cassette is placed under the forearm to include the
wrist joint and the elbow joint.

• The arm is adjusted such that the radial and ulnar styloid
processes and the medial and lateral epicondyles are
equidistant from the cassette.
• The lower end of the humerus and the hand are immobilized
using sandbags.

Direction and centring of the X-ray beam
• The vertical central ray is centred in the midline of the
forearm to a point midway between the wrist and elbow
joints.

2.Lateral
Position of patient and cassette
• From the antero-posterior position, the elbow is flexed to 90
degrees.
• The humerus is internally rotated to 90 degrees to bring the
medial aspect of the upper arm, elbow, forearm, wrist and hand
into contact with the table.
• The cassette is placed under the forearm to include the wrist joint
and the elbow joint.

• The arm is adjusted such that the radial and ulnar styloid
processes and the medial and lateral epicondyles are super-
imposed.
• The lower end of the humerus and the hand are immobilized
using sandbags.
