Medial plantar nerve
Dr Sarah Robertson and Dr Geon Oh et al.
The medial plantar nerve is the major sensory nerve in the sole of the foot.
Summary
- origin: larger terminal division of the tibial nerve
- course: from its origin under the flexor retinaculum, it passes deep to abductor hallucis, then appears between it and flexor digitorum brevis, gives off a medial proper digital nerve to the hallux, and divides near the metatarsal bases into three common plantar digital nerves
- motor supply: four intrinsic muscles - abductor hallucis, flexor digitorum brevis, flexor hallucis brevis, and first lumbrical
- sensory supply: skin on most of the anterior two-thirds of the sole and adjacent surfaces of the medial three and one-half toes, which includes the great toe
