title: The mechanisms producing fracture-separation of the proximal humeral epiphysis.
abstract: Six mechanisms which may produce fracture-separation of the proximal humeral epiphysis are proposed. Four of them are illustrated by case reports. It is suggested that they may be differentiated by examination of the patient and study of the radiographs. In unstable fractures manipulation is indicated and, if performed with an understanding of the mechanism of injury, will produce a stable reduction.
