Summary
origin: smaller terminal division of the tibial nerve
-
course:
lateral plantar nerve enters the sole of the foot by passing deep to the proximal attachment of the abductor hallucis muscle
it continues laterally and anteriorly across the sole between the flexor digitorum brevis and quadratus plantae muscles, supplying branches to both these muscles, and then divides near the head of the 5th metatarsal into deep and superficial branches
motor supply: abductor digiti minimi, quadratus plantae, 2nd, 3rd and 4th lumbricals, adductor hallucis, flexor digiti minimi brevis, dorsal and plantar interossei
sensory supply: strip of skin on the anterolateral anterior two-thirds of the sole and the adjacent plantar surfaces of the lateral one and one-half digits
