Abstract

Case presentation: A snowmobile racer fell from his sled and was run over by another, sustaining "shark bite" to his hand and leg. He was evacuated to a trackside medical trailer where the characteristic wounds were felt to require further exploration at a hospital.

Discussion: "Shark bite" is a colloquial term for lacerations sustained from metal studs attached to a snowmobile's track. "Shark-bite" lacerations may be more prone to complications than other lacerations commonly sustained in motorsports events.

Image of the left thigh and calf demonstrating four deep lacerations as well as multiple abrasions. These lacerations (arrows) are referred to as “shark bite” in the world of Snocross competition due to their resemblance to wounds experienced by those in a shark attack. They occur when the rider is run over by the metal treads of the snowmobile track. They are powerful enough to tear through the racer’s thick winter gear to cause these deep lacerations.
