- Common peroneal nerve
- Lateral branch of the sciatic nerve
- Winds around the neck of the fibula → divides into:
- Superficial Peroneal nerve
- Runs in the lateral compartment of the leg and pierces the fascia mid way down
- Motor: lateral compartment (fibularis longus and brevis → eversion)
- Sensory: lower anterolateral leg and dorsum of the foot (except first web space)
- Deep Peroneal nerve
- Runs in the anterior compartment of the leg
- Motor: anterior compartment (tibialis anterior, EDL, EHL, fibularis tertius) + dorsum of foot (extensor digitorum brevis)
- Sensory: first web space of foot
