Lateral and Medial Plantar Nerves

Peer Review Status: Internally Peer Reviewed

The first and second lumbricals may receive branches from both the lateral and medial plantars. The branch of the lateral nerve to the second lumbrical courses forward, beneath the transversus (adductor hallucis), then turns backward over the transversus (adductor hallucis) to reach the lumbrical muscle.

Cruveilhier described a branch of the lateral plantar that pierced the transversus to reach the third lumbrical.

The lateral nerve rarely provides a branch to the lateral head of flexor hallucis brevis.
