Entrapment neuropathy of the deep peroneal nerve associated with the extensor hallucis brevis.

The authors report a case of entrapment neuropathy of the deep peroneal nerve associated with the extensor hallucis brevis. This entrapment neuropathy was found distal to the inferior retinaculum that causes the anterior tarsal tunnel syndrome. Surgical decompression of the deep peroneal nerve that was entrapped by the extensor hallucis brevis relieved the symptoms. This condition, like the anterior tarsal tunnel syndrome, deserves attention.
