tibial nerve lesion
Last reviewed 01/2018
Damage to the tibial nerve is uncommon. Most usually, there is paralysis of gastrocnemius which is easily tested by asking the patient to stand on tiptoe. Plantar flexion and inversion of the foot are also weakened. The ankle jerk is absent.
Entrapment of the posterior tibial nerve at the level of the medial malleolus causes posterior tarsal syndrome. It is characterised by pain in the sole. Treatment is by surgical decompression.
