BACKGROUND: Traumatic digit amputations are common hand injuries in the United States. The primary aim of our study was to describe the relationship between season and mechanisms of amputation.
METHODS: The Emergency Department and Orthopaedic Surgery Billing Department databases of our level І institution in the Northeast were reviewed to identify patients with a traumatic digit amputation between January 2010 and December 2015. Inclusion criteria were defined as any patient presenting with a partial or complete amputation through Verdan zone I or II. All patient information was entered into a secure database, including date of injury, demographic information, digits amputated, mechanism of injury (crush, laceration, avulsion, bite, blast, saw, snow blower, or lawn mower), and Verdan zones of amputation. In addition to descriptive statistics, Fisher exact and χ2 tests were used to compare the incidence of these traumatic digit amputation mechanisms between seasons.
RESULTS: For this 6-year period, an average of 24 patients presented each season for treatment of a traumatic digit amputation. Of all seasons, spring had the highest proportion of lawn mower amputations (62.5%; P <.0001), summer had the highest proportion of blast amputations (75.0%; P =.011), and winter had the highest proportion of snow blower amputations (90.9%; P <.0001). All other traumatic digit amputation mechanisms had no significant seasonal variation in incidence ( P >.30).
CONCLUSIONS: Given that certain traumatic digit amputation mechanisms occur predictably during certain seasons, seasonal public education has the potential to prevent these debilitating injuries.
