Displaced talar neck fractures no longer constitute a surgical emergency; timing of definitive surgery has no bearing on the risk of osteonecrosis. Amount of initial fracture displacement is best predictor of osteonecrosis. Grossly displaced fractures or fracture-dislocations should be provisionally reduced, with or without temporary external fixation. Periosteal stripping should be limited to only that necessary to obtain anatomic reduction. Dissection within the sinus tarsi or tarsal canal should be avoided. Rigid internal fixation with solid cortical screws countersunk within the talar head and placed below the "equator" of the talar head is imperative for optimum stability.
