By a closer study of the literature, it will be noticed that in reports on fractures with a large fragment torn from the anterior tibial lip, illustrated by roentgenograms in two planes,1 fracture in the base of the medial malleolus is invariably found2 (Fig. 1).

A review of the case records of these fractures demonstrates that the fractures are always produced by a fall on the foot from a considerable height (10 to 13 ft. [3 to 5m.], three or four stories).

According to the mechanism of fall, the foot will go into pronation by
