Fx Classifications Flashcards
Essex-Lopresti tongue type fx
primary fx line (shear fx) which is intra-articular, spearates the sustentaculum tali from the lateral body, secondary fx line through the tuberosity, resembles beak fx
Fortins type 1
talar body fx, fx of talar body on any plane
Lauge-Hanson Supination-adduction
stage 1: rupture of lateral collateral ligaments +/or transverse fx of fibula below ankle joint
stage 2: vertical fx of medial malleolus, -pathomneumonic-talus moves medially, if talus has a vertical fx its a stage 2
