The medial and lateral plantar nerves may be evaluated through the recordings of the compound sensory nerve action potentials (csnap), compound mixed nerve action potentials (cmnap) and compound muscular action potentials (cmap). Once fusing, they are located posteriorly and centrally, gradually moving to a centrolateral position over the next 7.5 cm. The lateral plantar nerve (l), for the fourth web space.

It Classes Medially Being Located Between The 3Rd And Fourth Layers Of The Sole.

The Normal Values Obtained Are Higher In Amplitude Than Th.


The medial plantar nerve (m) provides digital nerves for the first three web spaces; In the end, the medial plantar nerve splits into three common digital plantar nerves and seven proper digital plantar nerves. The lateral plantar nerve is an important motor nerve in the foot because it innervates all intrinsic muscles in the sole, except for the muscles supplied by the medial plantar nerve (abductor hallucis, flexor digitorum brevis, flexor hallucis brevis, and first lumbrical).

Medial And Lateral Plantar Nerve Entrapment Symptoms.


The medial plantar nerve is the larger of the two terminal divisions of the tibial nerve, which accompanies the medial plantar artery. The medial plantar nerve supplies the abductor hallucis, flexor hallucis brevis, flexor digitorum brevis and. Entrapment in the medial longitudinal arch of the foot may result in altered sensation on the medial aspect of the sole of the foot.
