Eleven patients were treated for rollover injuries of the upper extremities from 1971 to 1976 resulting from the rollover accidents of off-road vehicles in rough terrain. Injuries to the volar surfaces of the extremity were most common, but injury to the extensor surfaces seemed to be more severe. Soft-tissue injuries predominated as did injury to the nondominant hand. The majority of patients returned to their original jobs after sometimes prolonged recovery and rehabilitation. A redesign of the rollover cage with interior hand holds could reduce the frequency and severity of these novel injuries.
