Proximal Fibula (Maisonneuve)

Maisonneuve injury = proximal fibular fracture + syndesmotic disruption + medial injury (deltoid/medial malleolus). Mechanism: external rotation with pronation. Examine entire fibula in ankle injuries; knee pain/tenderness is a clue. Management centers on syndesmotic stabilization; proximal fibula usually non-op. Avoid missing saphenous nerve injury or peroneal nerve palsy proximally.
