Antero-posterior View of Shoulder

The middle and outer parts of the clavicle are well seen and are common fracture sites. Check the acromio-clavicular joint to see if there is any subluxation or dislocation present. This should be confirmed by a weight-bearing view if suspected. 

Look for fractures and dislocations of the humeral head. Both anterior and posterior dislocations can be missed on this view unless another radiogram at a different angle is performed. Look for supraspinatus tendon calcification. Look for deformities of the rotator cuff, evidence of recurrent dislocation or occasional congenital foramina of the scapula.
