Peroneal Neuropathy (Foot Drop)

Peroneal neuropathy most commonly arises from compression of the nerve at the level of the fibular head, where it lies near the surface. Conditions such as crossing the legs, prolonged squatting, tight casts, and surgical positioning on the operating table can compress the nerve.

The classic presentation is 'foot drop'; the patient cannot lift the ankle upward and cannot walk on the heels. While walking, the toes catch on the ground and the patient must lift each step high.

Diagnosis uses physical examination, electromyography, and imaging when needed. Conservative or surgical treatment is planned based on the underlying cause; early diagnosis improves the chance of functional recovery.
