Definition
The common plantar digital branches of the lateral plantar nerve are terminal sensory branches that arise from the superficial branch of the lateral plantar nerve in the distal sole.
After the lateral plantar nerve courses obliquely across the plantar aspect of the foot, it divides into superficial and deep branches near the level of the base of the fifth metatarsal. The superficial branch of lateral plantar nerve splits into a proper and a common digital nerve; the proper digital nerve supplies the lateral side of the little toe, the Flexor digiti quinti brevis, and the two Interossei of the fourth intermetatarsal space; the common digital nerve communicates with the third common digital branch of the medial plantar nerve and divides into two proper digital nerves which supply the adjoining sides of the fourth and fifth toes.
