IntroductionPower saw and axe injuries are associated with significant morbidity and are increasingly managed in the emergency department (ED). However, these injuries have not been summarily reported in the literature. We aim to evaluate and compare the common injury patterns seen with use of power saws and axes.Materials And MethodsData from the National Electronic Injury Surveillance System- All Injury Program (NEISS-AIP) database was analyzed during 2006 to 2016. All patients with nonfatal injuries relating to the use of power saws or axes were included. Baseline demographics type and location of injuries were collected. Descriptive statistical analyses were performed using Chi Square or Fisher's exact test.ResultsInformation on (n = 18,250) patients was retrieved from the NEISS-AIP database. Injuries were caused by power saw n = 16,384 (89%) and axe n = 1866 (11%) use, and mostly involved males (95%). The most frequently encountered injury was laceration axe n = 1166 (62.5%); power saw n = 11,298 (68.9%). Approximately half of all injuries in both groups involved the fingers and hand. Most injuries occurred at home (65%) and were attributed to power saw use (89%).ConclusionsPower saws and axes can cause significant injuries, the majority of which occurred at home and were primarily associated with power saw use. Lacerations and injuries to the finger and hand were prevalent in both study groups. Further research into power saw and axe injuries should place emphasis on preventative measures and personal protective equipment (PPE).Level Of EvidenceIV Study type: Retrospective review.Copyright © 2018 Elsevier Inc.
