The deep peroneal nerve is the biggest of the two terminal branches of the common peroneal nerve
The deep peroneal nerve descends within the anterior crural compartment and supplies all the muscles of this compartment
It crosses in front of the ankle joint, giving an articular branch to the ankle joint, before the terminal branches innervate the dorsum of the foot, lateral to the dorsalis pedis artery
It innervates the skin of the interspace between the 1st and 2nd toes
It also innervates the digital extensor muscles and some of the tarsal and tarsometatarsal joints
