The strength of this text, based on comments from the first edition, is that the reader, particularly the newcomer to orthopedic surgery, is able to find all of the basics of the subject in one text. This concept enables the reader to come to grips with subjects that have only been touched upon in undergraduate teachings. The intent behind compiling the book is to form a bridge, or more properly a "firm callus", between the literature available for undergraduate students and those intending to study bone in depth. Though many texts already exist for undergraduates and also for students of advanced orthopedic surgery, few cover the bridge intended in this edition. It is hoped that the second edition will continue to set the stage for graduates undergoing training in orthopedics, be they surgeons in the medical, dental or veterinary field. All of the authors have an established reputation in the fields that they have covered in the enclosed chapters. It is essential reading for the budding orthopedic surgeon.
