To our knowledge, intrathoracic displacement of a fractured scapula has only been described in two reports involving adolescents1,2. We present the case of a skeletally mature adult with a scapular fracture that penetrated the thoracic cage without causing a pneumothorax. We speculate as to how the adult scapula can deform in a manner consistent with this rare injury. As the patient had advanced Alzheimer disease, the family consented to the publication of data concerning this case.
