This report describes a new hand injury seen in passengers in dune buggies having rollover accidents. Since these vehicles are usually driven off the road and far from treatment centers the treatment of these injuries is often delayed. As the rollover takes place, the reflex action—usually of the passenger—is to grasp the roll bar. A crush-avulsion injury occurs at the level of the metacarpals, with the thumb frequently spared. Wound contamination, delay in treatment, and the frequency of other serious injuries add to the seriousness of this injury. Redesign of the roll bar, provision of better passenger protection, and an internal grasp support are suggested to reduce its incidence.
