 The most common cause is habitual leg crossing that compresses the common fibular nerve as it crosses around the neck of the fibula.Transient trauma to the nerve can result from peroneal strike.Damage to this nerve typically results in foot drop, where dorsiflexion of the foot is compromised and the foot drags (the toe points) during walking; and in sensory loss to the dorsal surface of the foot and portions of the anterior, lower-lateral leg.
