It is the purpose of this report to review 47 patients hospitalized during the past 12 years with diaphragmatic rupture, secondary to impact injury. We have not included lacerations or perforations due to gunshot wounds or stab wounds.
Forty-seven patients hospitalized during the past 12 years with rupture of the diaphragm due to blunt trauma are studied (Table 1). In all but four instances an
