Luxatio erecta: a missed diagnosis.

A case of inferior glenohumeral dislocation (luxatio erecta) is presented. Although the classical presentation of luxatio erecta is considered pathognomonic, this case was initially misdiagnosed. This lead subsequently to the use of inappropriate reduction techniques. Eventually, the patient was taken to the operating room and closed reduction performed under general anesthesia. Follow-up examination demonstrated severe rotator cuff disruption without neurovascular deficit. Inferior shoulder dislocations are discussed and an explanation of the incorrect diagnosis is offered.
