Spontaneous Sternal Fracture — A Misnomer

Abstract

Spontaneous sternal fractures, although rare, may present to the Accident and Emergency Department as a severe central chest pain of sudden onset. These may be confused with myocardial infarction1 or pulmonary embolism2. Treatment in the uncomplicated case may be symptomatic with analgesics, but this fracture may require sternal wiring if paradoxical sternal movement embarrasses respiration. Spontaneous fracture of the sternum appears in the majority of cases to be due either to secondary metastatic infiltration, myelomatosis or extreme osteoporosis3. We report a case which emphasizes the importance of investigating these patients.
