It is with pleasure that we offer these introductory remarks for the Manual of Internal Fixation in the Horse, a book describing a further application of AO or ASIF techniques. The letters A-O stand for the Arbeitsgemeinschaft fUr Osteosynthesefragen and have been trans lated into the Association for the Study of Internal Fixation. The organization is truly a "study group", created in Switzerland, that met for the first time in 1958. The major goal was to establish a task of fracture treatment by force committed to the improvement osteosynthesis. The group's motivation arose out of the then prevailing unsound or inconsistently successful attempts at fracture treatment. According to statistics obtained from the Swiss National Health Insurance Program at the time, the so-called conservative treatment of fractures had resulted in a high rate of persistent morbidity. The problems encoun tered included: irreparable damage due to long-term immobilization; delayed union or pseudoarthrosis; malalignment; and, inadequate reduction of intraarticular fractures with resultant osteoarthritis. Accurate, stable osteosynthesis seemed the only practical way to address those various shortcomings. However, many of the osteosyn theses performed at that time had led to new problems, since most were not stable and, in some cases, actually worked to prevent healing.

Fractures in the Horse ist ein umfassendes zeitgemäßes Referenzwerk zu Frakturen beim Pferd. In den ersten 15 Kapiteln werden Grundlagen behandelt wie: * Struktur und Funktion der Knochen, physiologische Aspekte der Anpassung, Stressschutz und ultrastrukturelle Morphologie * Die Pathophysiologie von Knochenbrüchen, insbesondere die wesentlichen Merkmale von Knochenversagen, verschiedene Brucharten, Belastungsmerkmale, Spannung und Dehnung. * Die Epidemiologie von Frakturen mit geographischer, disziplinärer und pferdespezifischer Inzidenz, Risikofaktoren und Varianten sowie Vorhersagbarkeit. * Bildgebende diagnostische Verfahren wie Röntgen, Ultraschall, Szintigraphie, Magnetresonanztomographie, Computertomographie und Positronenemissionstomographie. * Behandlung akuter Frakturen, präoperative Planung, Anästhesie und Analgesie, Versorgung von stehenden Frakturen und Umgang mit Komplikationen. * Chirurgische Ausrüstung und Reparaturtechniken, externe Koaptation und Rehabilitation. In den 22 weiteren Kapiteln werden sämtliche klinisch relevanten Frakturen behandelt. Beschrieben werden jeweils die relevante Anatomie, die Frakturtypen, Inzidenz und Ursachen, klinische Merkmale und Erscheinungsformen, Bildgebung und Diagnose, Behandlung akuter Frakturen sowie Behandlungsoptionen und -techniken. Zudem enthalten die Kapitel eine Dokumentation der verfügbaren Ergebnisse sowie durchgängig Empfehlungen des Autors. Fractures in the Horse ist ein aktuelles Referenzwerk für alle, die sich mit Pferdemedizin beschäftigen. Es ist als Handbuch für Chirurgen, Diagnostiker, Assistenzärzte und Ärzte in Ausbildung geeignet. Tierärzten dient es als Nachschlagewerk für die Behandlung von Frakturen und vermuteten Frakturen in der Praxis, bei der Beratung der Tierhalter und der Entscheidungsfindung. Einzelne Kapitel sind auch für Anästhesisten, Chirurgen und klinisches Personal, das für die bildgebende Diagnostik zuständig ist, von Interesse.

Radius fracture configurations conducive to internal fixation most often contain a spiral or oblique fracture of the distal diaphysis. The location and fracture configurations are biomechanically challenging because of the limited amount of bone available distally for screw purchase and the complex three dimensional (3D) loading and unconstrained motions that occur in the distal radius. Development of an in vitro loading-measurement system that mimics in vivo unconstrained 3D relative motion of long bones, applies uniform load components over the entire length of a test specimen, and measures 3D relative motion to directly determine construct stiffness was verified. Stiffness results were comparable in magnitude to those theoretically predicted, and were consistently higher than results in the literature due to elimination of potting-fixture-test machine finite stiffness. Construct failure configurations were always reproducible with theoretical failure modes for bone. Biomechanical properties of the dynamic condylar screw (DCS) implant system and the double broad dynamic compression plate (bDCP) construct used to repair distal oblique diaphyseal osteotomies and ostectomies in adult cadaveric radii were compared. No statistical difference was observed between the DCS implant system and the bDCP construct stiffness during axial compression, torsion, or four-point bending; intact radii displayed the greatest stiffness. Torsion and four-point bending failure loads were not statistically different for the DCS implant system when compared to the bDCP construct.

This text provides broad coverage of all fractures, descriptions of surgical approaches, application of implants to specific bones, and fracture repair. Predisposing conditions, characteristic fracture patterns and incidences, options for treatment, and experiences with selected techniques make the text an authoritative, comprehensive volume. Many new techniques, approaches and implants are presented for the first time. Chapters are copiously illustrated with extensive line drawings, case photographs, and radiographs depicting diagnostic approaches and management techniques. Thorough descriptions of potential complications and likely outcomes are based on the contributors' extensive clinical experiences. Coverage is comprehensive, from basic bone science...to treatment of over 20 site-specific fractures...to postoperative considerations. Each chapter on a specific bone discusses the relevant anatomy, etiology and repair of various fractures.

Treatment of Equine Fractures provides equine practitioners with a rapid and comprehensive reference to the management of specific fractures in the horse. For each fracture type described there is a literature review and a detailed description of treatment illustrated with line drawings, radiographs and case histories followed by results of treatment and prognosis. Although AO/ASIF techniques are used extensively in many of the fractures described, other methods of fixation are included where appropriate. Arthroscopy, growth disturbances and arthrodesis are also included. This book will be an invaluable reference for practitioners and for final year and postgraduate students with an interest in equine fracture repair

After the publication of the AO book Technique of Internal Fixation of Fractures (Miiller, Allgower and Willenegger, Springer-Verlag, 1965), the authors decided after considerable discussion amongst themselves and other members of the Swiss AO that the next edition would appear in three volumes. In 1969, the first volume was published (the English edition, Manual of Internal Fixation, appeared in 1970). This was a manual of surgical technique which discussed implants and instruments and in which the problems of internal fixation were presented schematically without radio logical illustrations. The second volume was to be a treatise on the biomechanical basis of internal fixation as elucidated by the work done in the laboratory for experi mental surgery in Davos. The third volume was planned as the culminating effort based upon the first two volumes, treating the problems of specific fractures and richly illustrated with clinical and radiological examples. It was also to discuss results of treatment, comparing the results obtained with the AO method with other methods. The second and third volumes were never published. The second edition of the AO Manual appeared in 1977. It dealt in greater detail with the problems discussed in the first edition, although it still lacked clinical exam ples and any discussion of indications for surgery. Like the first edition, it was trans lated into many languages and was well received. Finally, after 22 years, the much discussed and much needed third volume has appeared.
