Unformatted text preview: Tarsal tunnel syndrome ( posterior tibial neuralgia) - is a condition that is caused by compression of the tibial nerve or its associated branches as the nerve passes underneath the flexor retinaculum at the level of the ankle or distally. Patophysiology: The nerves are responsible for transmitting afferent and efferent signals and for moving their own nutrients. The movement of these intracellular nutrients is accomplished through axoplasm (a type of cytoplasm within the nerve). The axoplasm moves freely along the entire length of the nerve. If the flow of the axoplasm is blocked, the nerve tissue distal to that site of compression is nutritionally deprived and susceptible to injury. Little bit of anatomy: The innervation of the branches of the posterior tibial nerve: ● Calcaneal branch ○ medial and posterior aspects of the heel ● Medial plantar branch ○ cutaneous branches to the plantar medial aspect of the foot ○ motor branches to the abductor hallucis and flexor digitorum brevis muscles...
