EDITORIAL NOTE

An American edition of this “ATLAS OF FRACTURES AND DISLOCATIONS," translated from the fifth German edition, is needed and will be welcomed by both students and practitioners.

Fractures and dislocations cannot be properly taught nor.understood without illustrations showing the visible external deformity, the X-ray shadow, the anatomic preparation, and the method of dressing. These are as necessary here as with anatomy.

The book of Professor Helferich, better than any yet published, answers the requirements for illustrations. We have much to thank the author for. Such a splendid collection of illustrations is possible only in a very large clinic, and represents time, labor, and great care. The work has been reviewed with pleasure and profit.

PREFACE TO THE FIFTH EDITION

The present edition has been enriched by the addition of nine skiagraphs and twenty-one text figures. The text of the epitome has been enlarged and corrected. The original intention of retaining the character of an epitome, and describing important matters more fully at the expense of questions of great rarity, has been adhered to. ACcordingly, I refrained from inserting, from the wealth of my skiagraphs, reproductions of rare conditions. On the other hand, the reader will find many new Röntgen-ray pictures illustrating the commoner fractures. To assist in the understanding of the Röntgen-ray plates, and I have no doubt many think this a very difficult matter, - I have taken skiagraphs of normal joints and added an explanatory outline sketch carefully prepared by Dr. Werner. It is to be regretted that we do not as yet possess any method of reproduction which would enable us to present pictures approaching in excellence the Röntgen-ray plates. Many of the Röntgen-ray pictures were reproduced directly from original plates of larger size (as, for instance, the nine plates representing normal structures, Plate 6, and textfigures 97, 105, 106, 156, 157, and 158). Others were reproduced from drawings by Dr. Werner, copied from original plates and photographs. These are Plate 7, and the text-figures 2, 3, 66, 76, 80, 82, 87, 90, and others.
