Reduction and preliminary fixation

Confirm the inclination of the humeral head.

Radiographic confirmation
The AP x-ray should show the correct relationship between the humeral head and the tuberosities.
Superolaterally, the humeral head and the greater tuberosity should be flush without a step-off or gap.
Confirm the inclination of the humeral head. The centrum collum diaphyseal angle (CCD) is illustrated. It is the angle between the axis of the humeral diaphysis, and the axis of the humeral neck, best identified as a perpendicular to the base of the humeral head. A CCD of less than 120° may predict a secondary collapse.
