Abstract:
We report clinical and electrophysiological findings in the four patients of anterior tarsal tunnel syndrome. All four patients, there was decreased pinprick sensation at the 1st interdigital space and limitation of digital dorsiflexion with atrophy of extensor digitorum brevis. Nerve conduction tests in the superficial peroneal, tibial and sural nerve were normal, but in the common peroneal nerve, the compound muscle action potential was decreased, while nerve conduction velocity between the knee and the ankle was normal with prolonged or upper normal limited terminal latency. Denervation potentials or giant MUPs had been found in the extensor digitonn brevis muscle, but absent in the tibialis anterior, extensor hallucis longus muscles.
