The "hangman's fracture" in infancy and childhood is a bilateral avulsion of the pedicles or their synchondroses from the C-2 vertebral body, frequently with anterior dislocation of C-2 or C-3. We present the case of the youngest infant in the medical literature with a hangman's fracture and discuss anatomy, kinematics of injury, radiographic diagnosis, and treatment.

The emergence of coronary artery thrombolysis and angioplasty have raised new questions about the transfer of patients with acute myocardial infarction (AMI). Since these modalities are generally limited in their availability, and since the success of thrombolysis is strongly time-dependent, the interfacility transfer of patients during AMI has become more common. Study of a relatively small number of patients indicates that aeromedical helicopter transport can be conducted in a safe manner, and that the outcome of management is of benefit to the patients. Reperfusion events, however, must be anticipated during transport of patients in whom thrombolysis is initiated preflight. Furthermore, initiation of thrombolytic therapy may be problematic if begun in patients with events mimicking AMI, particularly aortic dissection or Prinzmetal's angina.
