1. This is a follow-up study of fifty-seven vertical fractures of the neck of the talus in fifty-five patients. I examined and evaluated forty-three of the patients more than one year after injury.
2. A classifications based on the initial roentgenographic appearance of the fracture or fracture-dislocation is suggested.
3. Initial treatment is discussed with open reduction through a medial incision suggested.
4. Following anatomical reduction of a vertical fracture-dislocation of the talus, not complicated by avascular necrosis, a good or excellent result is the expected outcome.
5. The early-recognition of, the incidence of, and a plan for the treatment of avascular necrosis is discussed. The results of various methods of treatment of avascular necrosis of the talus are evaluated.
6. Following anatomical reduction of a vertical fracture-dislocation of the talus associated with avascular necrosis only a fair or poor result can be anticipated.
