Inferior Shoulder Dislocation, Anterior-Posterior View
Figure 3A demonstrates an inferior shoulder dislocation, also known as luxatio erecta. This type of dislocation is rare, with an incidence of less than 1% of all shoulder dislocations. The arm is raised, abducted, and fixed, with the humeral head subcoracoid in position. The patient often presents with their arm resting on top of their head.
