Abstract

Peroneal neuropathy can occur at any site of the nerve and the peroneal nerve can be injured about the fibular head by various kinds of injury or trauma, especially, by compression. Peroneal nerve palsy following adduction injury to the knee or fracture of the end of the fibula is well known. Less widely recognized is the impairment of nerve function that may follow an inversion sprain of the ankle. Peroneal nerve courses around the fibular neck and passes through a fibrosseous opening in the superficial head of peroneus longus muscle. This opening is quite tough and may make acute angulation as it passes through. So the nerve can be compressed at this site when it is stretched, as in the ankle inversion. We experienced an injury of the peroneal nerve about the fibular head following an inversion of the ankle, so we report a case of peroneal neuroapthy with electoromyographic data.
