[Tarsal tunnel syndrome].

The most prominent subjective complaints are loss of sensation and stress pains in the foot. The symptoms resemble the carpal tunnel syndrome in the hand. The reproducible local pain on pressure below the medial malleolus is the prinicpal clinical symptom. The treatment of choice is the division of the retinaculum flexorum and if necessary, neurolysis of the tibial nerve. Etiopathogenetically, congestions due to standing, local distension of veins, consequences of trauma, tenosynovits, local tumorous processes and abnormalities of the abductor of the great toe must be considered.
