The tibial nerve is the larger terminal branch of the sciatic nerve with root values of L4, L5, S1, S2, and S3. It lies superficial (or posterior) to the popliteal vessels, extending from the superior angle to the inferior angle of the popliteal fossa, crossing the popliteal vessels from lateral to medial side.
If non-invasive treatment measures fail, tarsal tunnel release surgery may be recommended. Tarsal tunnel release is a form of a nerve decompression to relieve pressure on the tibial nerve. The incision is made behind the ankle bone and then down towards but not as far as the bottom of foot. The posterior tibial nerve is identified above the ankle.
The condition is caused by compression of the posterior tibial nerve (which is found in your foot) and can cause symptoms like pain, tingling, or numbness in your foot, according to Johns Hopkins ...
Tarsal tunnel syndrome is the most commonly reported nerve entrapment of the ankle. It is analogous to carpal tunnel syndrome in the wrist. It is caused by compression of the tibial nerve underneath the flexor retinaculum of the foot. [1] People with tarsal tunnel syndrome have pain in the plantar aspect of the foot mostly at night.
The nerve that communicates to the muscles that lift the foot is the peroneal nerve. This nerve innervates the anterior muscles of the leg that are used during dorsiflexion of the ankle. The muscles that are used in plantar flexion are innervated by the tibial nerve and often develop tightness in the presence of foot drop. The muscles that keep ...
tibial nerve; common fibular nerve (also known as the common peroneal nerve) [3] popliteal vein; popliteal artery, a continuation of the femoral artery; small saphenous vein (termination) [3] Popliteal lymph nodes and vessels [3] It is of note that the common fibular nerve also begins at the superior angle of the popliteal fossa.

The sciatic nerve (L4-S3), the largest and longest nerve in the human body, leaves the pelvis through the greater sciatic foramen. In the posterior thigh it first gives off branches to the short head of the biceps femoris and then divides into the tibial (L4-S3) and common fibular nerves (L4-S2). The fibular nerve continues down on the medial ...
The medial plantar nerve from the tibial nerve provides sensory innervation to the skin of the medial side of the sole, the skin of the medial three and a half toes, and the nail beds of these toes. It also provides motor innervation to abductor hallucis, flexor hallucis brevis, flexor digitorum brevis, and the first lumbrical.
