Tarsal tunnel decompression

Tarsal tunnel syndrome classically presents with neurological symptoms effecting the sole of the foot.
Most commonly it is due to tight fascial layers or peri-neural fibrosis compressing the posterior Tibial nerve and its branches though extrinsic compression from ganglions and other space occupying lesions can less commonly cause the condition.
Nerve conduction testing is usually (though by no means invariably diagnostic) but physical examination is more often equivocal.
Surgical treatment if performed with rigorous attention to detail is highly successful in my experience and warranted in symptomatic cases irrespective of their chronicity. Pain is most consistently dealt with by the Tarsal tunnel release and the earliest feature expected to improve.
