Posterior tibial neuralgia

Refers to the spread of pain along the posterior tibial nerve (neuralgia). The posterior tibial nerve passes through the fibrous bone canal in the umbilical ligament at the plane of the ankle and divides the medial and lateral plantar nerves at the exit. Sacral canal syndrome refers to the compression of nerves in this fibrous canal, but this diagnosis has not been strictly used for posterior tibial neuralgia caused by different reasons.
