›Fracture pattern by mechanism

›Torsional forces — spiral fractures with fibula intact

›Direct trauma — transverse or comminuted fractures

›Axial loading — segmental or comminuted patterns

›Fatigue loading — stress fractures in athletes and military recruits

›Anterior compartment — tibialis anterior, extensor hallucis longus, deep peroneal nerve

›Lateral compartment — peroneal muscles, superficial peroneal nerve

›Superficial posterior compartment — gastrocnemius, soleus, sural nerve

›Deep posterior compartment — tibialis posterior, flexor digitorum longus, posterior tibial nerve and vessels

›Compartment syndrome pathophysiology
