Atypical deep peroneal neuropathy in the setting of an accessory deep peroneal nerve.
We report a case of deep peroneal neuropathy resulting in foot drop with preserved toe extension. These unexpected findings were the result of the presence of an accessory deep peroneal nerve that provided total innervation of the extensor digitorum brevis. We review the literature on total innervation of the extensor digitorum brevis by the accessory deep peroneal nerve with and without an associated deep peroneal nerve lesion.
