[Distal nerve compression of the leg. Clinical and electrophysiologic study].
Rare distal compressions of lower limb nerves include tarsal tunnel syndrome, entrapment of the first branch of the lateral plantar and medial calcaneal nerves, interdigital neuroma, compression of the deep peroneal nerve on the dorsum of the foot, entrapment of the superficial peroneal and sural nerves. Nerve conduction and electromyographic studies are essential to evaluate these peripheral nerve injuries in order to differentiate focal lower extremity nerve entrapments from ischemic mononeuropathies, lumbar radiculopathies or plexopathies, and generalized peripheral neuropathies. This review summarizes the clinical and electrophysiological findings for each of these rare entrapment syndromes and provides the necessary clues to obtain a correct differential diagnosis with other more common causes of foot and ankle pain and paresthesias.
