Background Blunt injuries to the adrenal glands are considered rare, associated with severe injury, and highly mortal, based on autopsy series and earlier retrospective reviews. Recent studies have reported higher incidence rates associated with lower injury severity and mortality rates.
Methods A 3-year review of the Pennsylvania Trauma Outcomes Study Registry of adults with intra-abdominal injuries after blunt trauma was performed and associated organ injuries, injury parameters and in-hospital mortality were compared between those with and those without adrenal gland injury.
Results 5679 patient records were identified, 439 with adrenal gland injuries and 5240 without. The liver and the kidney were the intra-abdominal organs most frequently associated with injuries to an adrenal gland, and the spleen was the intra-abdominal organ most frequently injured in those without an adrenal gland injury. There was no difference in mortality rates.
Discussion Injuries to the adrenal gland occur with an incidence of 0.43% after blunt force trauma. The presence of a blunt adrenal gland injury is not a marker of severe injury or associated with an increased mortality rate.
Level of evidence II, Retrospective Study.
