Lethal and sublethal injuries to infants caused by anteroposterior manual compression can be accompanied by lateral rib fractures, hemorrhage into the viscera, and when severe, rupture of large vessels and solid organs. Abusers may claim that these injuries were sustained in an attempt to perform cardiopulmonary resuscitation (CPR). The difference between injuries caused by CPR and injuries caused by inflicted anteroposterior compression is examined in one sublethal and two lethal cases.
