Inferior dislocation of shoulder It is caused by severe hyper abduction force. With the humerus as the lever and acromion as fulcrum, the humeral head is lifted across the inferior rim of the glenoid socket and pokes into axilla subglenoid position. It is rare and also called luxatio erecta because the humeral head is subluxated dislocated anteriorly and humerus shaft points upwards erected. The staing picture of a patient with hisher arm locked in almost full abduction elevation, should make the diagnosis quite easy. The patient comes with hisher arm fixed almost by the side of the head. Potentially serious consequences e.g. neurovascular damage is quite common. It is reduced by pulling upward in the line of abducted arm with counteraction downwards. Ref: Rockwood and Greens Fractures in Adult 6e, Page 1287.
