The deep peroneal nerve is a branch of the common peroneal nerve that innervates foot dorsiflexors in the anterior compartment and toe dorsiflexors in the foot. It provides sensory supply primarily to the interspace between phalanges 1–2, as well as some minor supply to the articulation of the ankle. It can be injured near its origin around the fibular head, leading to foot drop, or as it passes through the anterior tarsal tunnel, leading to Anterior Tarsal Tunnel Syndrome, which presents with dorsal foot pain radiating to the lateral tarsometaltarsal joints. Conservative management is first line therapy, with surgical intervention reserved for recalcitrant or complicated cases.
