Common peroneal nerve injury

After the sciatic nerve was separated, it slanted downward along the medial edge of the biceps femoris and passed through the outside of the popliteal fossa to reach between the biceps femoris tendon and the lateral head of the gastrocnemius. Deep peroneal and superficial peroneal nerves. Dominate the peroneus longus, tibialis anterior, long extensors, long toe extensors, long short extensors, short toe extensors, and skin sensations on the outside and back of the calf.
