Answer B) Peroneal
Explanation: Inability of dorsiflex and foot eversion with sensory loss over front and outer half of leg and dorsum of foot are seen in peroneal nerve injury
Peroneal Nerve
-
The common peroneal nerve often referred to as the common fibular nerve, is a major nerve that innervates the lower extremity. It is one of the two major branches off of the sciatic nerve and receives fibers from the posterior divisions of L4 through S2 nerve roots
-
The nerve curves around the fibular neck before dividing into two branches, the superficial peroneal nerve (SPN) and the deep peroneal nerve (DPN).
The superficial peroneal nerve innervates the lateral compartment of the leg, and the deep peroneal nerve innervates the anterior compartment of the leg and the dorsum of the foot.These two nerves are essential in eversion of the foot and dorsiflexion of the foot, respectively.
