Lauge Hansen SA Supination ADduction (Inversion) Ankle Fracture

Surgery of the Foot and Ankle: http://astore.amazon.com/nichogiovi-20 Popular Running Shoes: http://astore.amazon.com/nichogiovi-2... With the foot in a fixed supinated position a lateral Adductory force is exerted along the lateral malleolus as the talus inverts with-in the ankle mortise. In Stage 1, one of three injuries may occur, a rupture of the lateral collateral ligaments, an avulsion fracture the lateral malleolus, or a transverse fracture of the distal fibula below or at the level of the ankle joint.  (Note: The syndesmotic ligaments are not involved with Supination ADduction injuries). If the ADductory force continues medially the talus will abut against the tibia and progress to a Stage 2 injury resulting in an oblique to near vertical fracture of the medial malleolus.   One must note that this is a multi-factorial injury; the relative position of the foot, the amount of force involved, and the inherent strength of both the ligamentous and osseous structures all play an intricate role in the development of this type of injury.   (Take home points) Rupture of the lateral collateral ligaments or a fracture of the fibula below the level of the ankle joint in stage 1.  Oblique to near vertical fracture of the medial malleolus seen in stage 2.
