FRACTURE OF THE LOWER ARTICULAR SURFACE OF THE TIBIA IN FRACTURE DISLOCATION OF THE ANKLE

1. Posterior and anterior marginal fractures of the tibia occur not infrequently as complications of fracture dislocation about the ankle, and account for many of the bad results in this class of cases.

2. The posterior marginal fracture is most often accompanied by a fracture of the lower end of the fibula and of the medial malleolus, and should be treated in the same way as the ordinary Pott's fracture, special attention being paid to the prevention of recurrence of the backward dislocation of the foot.

3. Anterior marginal fracture may be associated with fracture of both malleoli, and anterior dislocation of the foot.

4. In the treatment of both these fractures complete reduction of the dislocation and restoration of the integrity of the inferior articular surface of the tibia must be obtained, either by manipulation or by open operation.
