Common-Peroneal-Nerve Injury

Common-peroneal-nerve injury (at the fibular head) causes foot drop (inability to dorsiflex/evert the foot) and numbness over the lateral leg/dorsum of foot. Risk factors: leg crossing, squatting, weight loss, fibular-head trauma. Treatment: avoid compression, ankle-foot orthosis, observation for recovery; surgical exploration/decompression in severe or traumatic cases.

Common Symptoms

Foot drop; steppage gait; lateral-leg/dorsum-of-foot numbness; history of leg crossing/squatting/trauma

Treatment

Avoid compression; ankle-foot orthosis; observe recovery; surgical decompression if severe/traumatic

Preventive Measures
