Trauma and Injury Handbook for Orthopaedic Exams An essential companion to every budding trauma and orthopaedic surgeon, especially in trauma meetings and exams. Along with a comprehensive classification list, we have endeavoured to give evidence behind the common controversies that arise in orthopaedic trauma. The use of orthopaedic classifications as a means of testing the academic ability of trainees has been a common if not ever present factor in every teaching or trauma meeting throughout the world. The initial consideration for this book arose following regular debates of such classification origins, basics and even false representations. A number of classifications have evolved over the years like classic Chinese whispers, with a number of modifications replacing their original descriptions. Examples of theses include the regularly used Rockwood classification for ACJ dislocations, which is actually a modification of the Allman classification from 1967. However, the Allman classification for clavicle fractures, which originates from the same paper, is almost an endnote within the paper. The commonly referenced Weber classification of ankle fractures was initially described by Danis in 1949. Gartland’s classification of paediatric supracondylar fractures has had a number of modifications, most of which by Wilkins in his book ‘Fractures in children’. Confusingly, he changes his modifications from edition to edition, leading to many mistakes in published literature. These are only a few examples of this failure in referencing. We have attempted in all cases to return to the original papers, although in some cases this was impossible. In some cases (for example Seddon’s classification of nerve injuries) the authors have published their classifications in more than one journal. And in this instance we have given both examples if there are alterations in their description.
