Anterior tarsal tunnel syndrome: case repot

The anterior tarsal syndrome, a compression of the deep fibular nerve under the inferior extensor retinaculum, is a very rare entrapment neuropathy. Its most important symptom is nocturnal pain on the dorsum of the foot. The distal motor latency of the deep fibular nerve is prolonged, and the EMG demonstrates an active and chronic denervation of the extensor digitorum brevis muscle. One case of complete lesion of the deep fibular nerve in the anterior tarsal tunnel is presented as well as a discussion of its physiopathology.
