Anterior dislocation of the shoulder is far the commonest, representing more than 95% of all shoulder dislocations.

It the context of trauma is is essential orthogonal views are acquired to assess for dislocation and the associated concerns of fracture, a Hill-Sacs deformity, bony Bankart abnormality and rarely a lipohemarthrosis.  This comprises an AP view with either a axial, modified axial or Y view as patient circumstances dictate.

Post-reduction films are also undertaken to confirm restoration of the normal anatomical position.
