Lateral Plantar Nerve[edit | edit source]
The lateral plantar nerve (LPN) or external plantar nerve (latin: nervous plantaris lateralis) is a terminal branch of the tibial nerve. The LPN enters the foot passing deeply into the abuctor hallucis muscle, then is directed anteriorlly and laterally through the sole between the flexor digitorum brevis and quadratus plantae muscles, medial to the lateral plantar artery. It divides into a superficial and a deep branch.
It is a is a sensorimotor nerve, it inervates all the intrinsic musculature of the foot sole except from (abductor hallucis, flexor digitorum brevis, flexor hallucis brevis, and first lumbrical). Sensory it inervates a skin band located on the lateral face of the two anterior thirds of the sole, aswell as the adjacent surfaces of the fisth and half of the fourth toe.
