During the period from 1932 to 1934 there were admitted to the fracture service for females at the Cook County Hospital patients with 3,294 fractures. The fractures, dislocations and tears in the ligaments of the ankle numbered 352, or 10.84 per cent of all fractures. These were reduced and treated subsequently in the follow-up clinic. Our data are based on the records of the hospital and the follow-up clinic and on our study of 300 of the hospital's roentgenograms.
We are adding to these data the results of a study of 78 fractures of the ankle encountered in private practice, with a review of the roentgenograms. Our work, therefore, is based on a study of 430 fractures of the ankle and a review of the roentgenograms of 378.
The clinical study of these fractures has been augmented by a detailed description of the practical anatomy and physiology of the ankle
