SUMMARY

1. Peroneal nerve: L4, L5, S1, S2. Innervates the PERONEUS LONGUS AND BREVIS, responsible for eversion of the foot.

2. Tibial nerve: L4, L5, S1, S2, S3. Innervates the TIBIALIS POSTERIOR, responsible for inversion of the foot.

3. Typically occurs at the proximal head of the fibula, causing foot drop. Remember that L5 radiculopathy also causes foot drop.

4. Patients with peroneal neruopathy will not be able to evert the foot as only the PERONEUS LONGUS AND BREVIS are involved.

5. Patients with L5 radiculopathy will not be able to evert and invert the foot (as the lesion is higher up and PERONEUS LONGUS AND BREVIS, TIBIALIS POSTERIOR are involved).
