Posterior shoulder dislocation is a rare clinical condition that accounts for only 2-4% of all gleno-omeral dislocations. Posterior shoulder dislocation may be missed initially on frontal radiographs in 50% of cases, because the humeral head appears to be almost normally aligned with glenoid. The aim of this study was to illustrate the most important radiographic signs of the shoulder dislocation and to integrate these signs with computed tomography. The computed tomography confirms the diagnosis, identifies bone lesions not viewable with Conventional Radiography, assesses the extension of bone damage of the articular surface and establishes the most appropriate conservative or surgical therapeutic planning.
