This definitive version of the book is in the form of a high-quality large-format A4 looseleaf binder, to be practical in use and to optimise viewing of the content (because it lies flat). The looseleaf format also means that pages can be replaced when necessary, as surgical techniques develop; and brand new content from the authors can be added to the book. The HES Book is future-proofed, whereby it will evolve over time in line with developments in the field - there will be no waiting around for the publisher to print a new edition! ​If you already have a copy, you will be able to download page updates for free.
