What is the difference between posterier tibial tendon dysfunction and tarsal tunnel syndrome?

Tendon vs. Nerve: Pttd is a a tearing and degeneration of the tendon that holds up your arch it assists in rising up on toes. As it stretches out it can cause an increasing flatfoot deformity and ultimately hindfoot arthritis. Tarsal tunnel syndrome is a constriction of the posterior tibial nerve as it passes behind and around the medial ankle. It can cause pain, numbness and weakness of the intrinsic foot muscles.

Flat feet: Here is the simple answer....Posterior tibial tendon dysfunction or pttd is a flat foot deformity. It could be rigid or flexible and present with pain at the arch or heel area. Tarsal tunnel syndrome or tts is a compression syndrome (such as carpal tunnel syndrome in the hand) of the posterior tibial nerve. Pttd can cause tts. Therapy can vary significantly. Treatments include orthotics to surg.

RE: PTTD: Posterior tibial dysfunction is a tendon issue where the tendon on the inside of your foot/heel does not do a very good job of supporting the area. Tarsal tunnel syndrome is an entrapment/aggravation of the tibial nerve near the inside of your heel. Both of these structures anatomically pass through the "tarsal tunnel" and can exhibit similar pain profiles.

The difference is: tarsal tunnel refers to a compression or pinching of the tibial nerve, may cause symptoms consistent with pain, numbness, burning, loss of sensation on bottom of feet, can case these symptoms in the heel as well as the toes. Posterior tibial tendon dysfunction is a condition where the tendon which causes the arch to rise when walking starts to degenerate and can eventually tear or rupture.
