EXACT knowledge of the mechanism, pathologic anatomy, genetic
roentgenologic diagnosis and genetic reduction of fractures of the
ankle is to be attained by combined experimental-surgical and experimental-roentgenologic investigations.1 In this study the mechanism of
fracture was determined by fracturing, the pathologic anatomy was
ascertained by dissection, the genetic roentgenologic diagnosis was
established by roentgen examination and the genetic reduction technic
of the fractures was found by reduction maneuvers, which will be
dealt with in a later paper, "Clinical Use of Genetic Roentgenologic
Diagnosis and Genetic Reduction."
