This reference work presents a classification of fractures of all long bones. The fundamental principle of this classification is the division of all fractures of a bone segment into three types and the further subdivision into three groups and their subgroups. The groups are arranged in an ascending order of severity according to the morphologic complexities of the fractures, the difficulties inherent in their treatment and the prognosis. Thus, once a surgeon classifies a fracture, he will have determined its severity and he will have a guide to its best possible treatment."

It is to the great and lasting credit of LORENZ BOHLER and his school that they have in the last decade developed and demonstrated so thoroughly the techniques for the conservative management of fractures. Nevertheless there have always been many, including some from BOHLER'S school, who have found considerable place for surgical management, and with the significant progress in general surgery seen in postwar years, a new stimulus has been given to this part of traumatic surgery, especially since bone injuries have become more complex and frequent. The concept of internal fixation is not new....
