Answer

A patient with a posterior dislocation presents with the affected arm held in adduction and internal rotation. Efforts by the examiner to abduct or externally rotate the extremity result in pain and very little movement. Additionally, a prominent acromion and coracoid are typically noted, with the humeral head palpable posteriorly. These findings may be obscured if swelling is massive swelling or if the patient is particularly large.
