Answer

As with all limb injuries, the neurovascular status of the limb must be assessed. This assessment consists of palpation of the dorsalis pedis and posterior tibial arterial pulses. Testing for sensation, especially over the sural nerve distribution, is also necessary; sural nerve and peroneal nerve palsies, although rare, may complicate a lateral ligamentous injury. Electromyographic examinations of individuals with severe ankle sprains have shown that 80% of these patients have some degree of peroneal nerve injury.
