The original AO/ASIF Instrumentation manual presented a concise and complete description of the AO instruments. Thoughtfully developed by Fridolin Sequin and Rigmor Tex hammar, the manual discussed in a clear fashion the purpose and care of the various AO instruments that are handled by the operating room staff. One important feature of the first edition was a detailed checklist of the instruments required for the more common operative procedures for treating fractures. Fridolin Sequin was well-suited to author the first edition: his 15 years of experience as a technical engineer for the AO gave him in-depth knowledge of AO instruments, and he drew on the clinical knowledge of Rigmor Texhammar, a consultant and di rector of the AO courses for nurses. Its original feature of com bining a column of text with a column of illustrations meant the manual quickly became accepted as a standard. By 1981, trans lations could be found in English, French, Spanish, and Italian. Not surprisingly, the manual was very popular.

During their 20 years of activity members of the Associa tion for the Study of Internal Fixation (AO - ASIF) have made authoritative contributions to the development of internal and external fixation. The close collaboration of surgeons, basic researchers, metallurgists, engineers and the establishment of clinical documentation has made it possible to achieve a solid scientific basis for internal fixa tion. Clear definitions for the standardization of different types of osteosynthesis were possible: interfragmentary compression, splintage and buttressing as well as combina tions of these three techniques. At the same time a scienti fic and workmanlike instrumentation was developed. The idea was to keep diversification within limits but, however, to assemble a comprehensive collection of implants and in struments to answer all the problems presented by the com plexity of bone operations. Osteosynthesis is a difficult and demanding operative method. Its. claims on the surgeon and the theatre staff are high. Therefore plans have existed for a long time to supplement the "Manual of Internal Fixation" with a de tailed description of the AO Instrumentation, its use and maintenance. Our collaborator FRIDOLIN SEQUIN, graduate engineer, has accomplished this task with expert knowledge. He has organized over many years courses for theatre nurses and has been able from the resulting experience to provide helpful suggestions. When RIGMOR TEXHAMMAR R. N. joined AO-International four years ago, it was natural to include her as a co-author.
and refinement that exists within the necessarily strict rules of the internal fixation method. In this way we seek to contribute to as weIl as to stimulate the search for rational solutions to surgical problems. It is assumed throughout that the reader is fa miliar with the technical fundamentals of internal fixation, and so these details are omitted. Instead, special indications and technical refinements are presented on the basis of case examples. Because an endless variety of situations can arise in orthopedic surgery (a circumstance that is attracting more and more surgeons to the field), we have taken ca re that our examples can readily be applied to novel situations. We now credit, in alphabetic order, those who contributed most to the techniques presented: R. BLATTER, A. BOITZY, C. BRUNNER, O. CECH, A. DEBRUNNER, F. MAGERL, G. SEGMÜLLER, G. STÜHMER, and B.G. WEBER. We thus express thanks to those colleagues in our clinic who agreed to having their ideas published. But we are also grateful to our illustrators, H. and K. SCHUMACHER, our photographer, M. SCHAFFNER, and our chief secretary, U. OETLIKER, who contributed so much to the preparation of the manuscript. Finally, we thank Springer-Verlag for their patience with us and especiaUy for their efficient work in bringing the book to press. St. GaU, Fall 1981 CH.F. BRUNNER B.G.

The rigid internaI fixation of mandibular fractures has become a widely ac cepted practice among European surgeons. The caution or even outright re jection voiced at a congress of the German Society of Maxillofacial Sur 1970s is no longer prevalent. Through a process of geons held in the late critical review and implementation, rigid internaI fixation has become an established treatment modality at numerous centers, especially in Switzer land, the Federal Republic of Germany, and the Netherlands. By comparison, the method has received very little attention in North America and the Anglo-Saxon countries. By and large, surgeons in these countries continue to treat mandibular fractures by intermaxillary fixation, possibly supplemented by the use of interosseous wires. Many recent edi tions of surgical texts confirm this. Lately, however, there appears to be a surge of interest in methods of functionally stable internaI fixation, especially in the United States of America, and AO/ ASIF instruction courses are increasingly in demand. This book is intended to aid course participants in their lessons and practi cal exercises and also to guide the clinical practitioner in the application of AO/ ASIF principles. Basel, September 1988 B.SPIESSL VII Acknowledgments I have received help from many sources. The colleagues of the past 20 years who have contributed to the case material upon which this manual is based are too numerous to credit by name.

The Manual of INTERNAL FIXATION is well known internationally as a standard work for every specialist dealing with osteosynthesis. Due to the many changes that have taken place, an international faculty of orthopaedic surgeons and traumatologists completely revised and expanded the manual. In its third edition the manual reflects the state of the art and is the necessary reference for every AO specialist.
This reference work comprehensively covers essential orthopedic trauma implants and their application in both upper and lower limbs. It offers insights into the invention, advantages, and disadvantages of various implants, along with the rationale behind their current designs, biomechanics, and materials. Additionally, the book addresses fracture fixation and general considerations when comparing different subgroups of implants, such as nails versus plates or ORIF versus external fixation. The book is divided into several sections, such as upper and lower limbs, spine, and pelvis. It also includes unique sections dedicated to pediatric implants, implant removal, metallurgy and bone grafts. It is written and edited by experienced surgeons from around the world. This book fills the gap as currently, there are no specific reference books on this topic but only operative manuals and inventory lists of various commercial companies detailing their own products. This highly informative and meticulously presented book serves as both a practical and a theoretical guide for practicing orthopedic surgeons, scientists/researchers, academicians, students as well as orthopedic technicians and nurses.
This book has become necessary as a consequence of the rapid expansion of the surgical procedures and implants available for spinal surgery within the "AO Group". We have not attempted to write an in-depth book on spinal surgery, but one which will help the surgeon in the use of AO concepts and implants. We con sider the practical courses held all over the world essential for the teaching of sound techniques so that technical complications and poor results can be avoid ed for both the surgeon and, in particular the patient. This book is a practical manual and an outline of what is taught in the courses. It is intended to help the young spinal surgeon to understand the correct use of AO implants. The indi- tions given will aid the correct use of each procedure. . It must be strongly emphasized that surgery of the spine is technically de manding. The techniques described in this book should only be undertaken by surgeons who are trained and experienced in spinal surgery. Certain techniques, in particular pedicle screw fIxation and cages, have not yet been fully approved by the FDA in the United States. However, throughout the rest of the world, the use of pedicle screws has become a standard technique for the spine surgeon, since it has been shown to improve fIxation techniques and allow segmental correction of the spine. The use of cages has become more and more popular, specifIcally as a tool of minimally invasive spinal surgery.
