This volume, edited by an orthopaedic surgeon, contains contributions from fellow surgeons as well as practitioners of neighbouring fields such as radiology and engineering. The chapters are organized into four sections: after a survey chapter on orthopaedic surgery from the eighteenth to the twentieth century, section one on ‘Major advances in the twentieth century’ deals with arthroplasty of the hip and the knee, arthroscopic surgery and orthopaedic trauma. The second section, entitled ‘The scientific background’, contains chapters on biomechanics, biomaterials, and orthopaedic radiology, whereas the third section under the title ‘Fragmentation of orthopaedic surgery’ covers various specialized subfields, such as hand and spine surgery. The last section consists of only one chapter, ‘Orthopaedics in 2050’, and is devoted to the field's future. The editor and authors have clearly spent a lot of time and energy on this book, their specialized knowledge and experience being an invaluable resource. The amount of material accumulated is daunting, the degree of medical expertise used to evaluate it impressive. Medical historians who are interested in the technical aspects of orthopaedic surgery will thus be delighted to find so many useful leads collected in one place. However, doctors are not historians and one should not expect this book to meet the standards of professional historical practice. Problems arise when the authors depart from their fields of expertise and turn to more general historical subjects. This is most obvious in the survey chapter, which contains a number of factual errors and historical misjudgements. Thus, the importance of Lister's work does not really lie in the application of Pasteur's discoveries, nor was Johannes Muller the founder of scientific medicine in Germany. In both instances it is easy to see how the misconceptions came about and how they could have been prevented by a conversation with a medical historian. Similarly, consultation of an expert in medical history could have steered the authors away from their reliance on encyclopaedia articles and general textbook chapters toward relevant literature on the subject. To mention one example, Roger Cooter's seminal work on Surgery and society in peace and war: orthopaedics and the organization of modern medicine, 1880–1948 (Basingstoke, 1993) is not quoted anywhere in the volume. The evolution of orthopaedic surgery shows the degree to which historians and medical practitioners live in different intellectual worlds. Like most medical practitioners, the authors of this volume assess past events according to present standards. This is what scientists and doctors usually do in the introductory section of their scientific articles. There they comment on previous work, evaluating it as to its strengths and weaknesses in order to create a suitable context for presenting their own work. It is in this sense, then, that books like the present one are best understood. Such contributions by medical practitioners are certainly useful and deserve to be praised: on the factual level, they offer a lot of information to the historian. Moreover, they provide a source for understanding practitioners' aims and objectives. However, as long as the agendas differ so much between historians and doctors, and as long as there is so little co-operation between them, volumes like this one cannot be seen as a meaningful contribution to the critical analysis of past developments that historians of medicine are striving for.
