The typical symptom in common peroneal nerve injury is foot drop. The common peroneal nerve passes posterior to the popliteal fossa to the anterolateral aspect, especially beneath the fibular tuberosity, and innervates the anterolateral calf muscles and a range of sensations in the dorsum of the foot. After injury, sensory deficits may occur, especially between the first and second toes, with specific areas of hypoesthesia or loss of sensation. Motor deficits are mainly manifested as foot drop, i.e., inability to hook the toes, and drooping of the big and little toes. Common causes of common peroneal nerve injury are compression, such as compression of the small head of the fibula when a cast is applied, which can lead to common peroneal nerve paralysis over time.
