I think some of these responses reflect an old reality. If you have a smart phone in your pocket, you don't need Handbook of Fractures. And, if you don't have any baseline knowledge on trauma care, the information in the Handbook aren't going to help much. Instead, I'd first of all recommend some basic chapters on internal fixation. Either Skeletal Trauma's relevant chapter, or Rockwood's, or the AO Handbook - whatever your library has access to - it is way better to understand principles then waste time memorizing random details you have no context for anyway. And go to the AO Foundation website and watch the videos on the basics of internal fixation, intramedullary fixation, and external fixation. Then, to prep for cases, check out the AOSurgery website/app. You can quickly see what the options are for treatment, what the approaches are, and learn about the major classifications. I think this website, made by the AO itself, puts Handbook into the history books.
Speaking of history, I am absolutely floored by the number of people who claim they want to spend the rest of their lives doing orthopaedic surgery, and don't even know what the word 'orthopaedic' means. When I interview, a blank stare to that question and you might as well move up your plane flight out of town. Want to know what an orthopaedic residency looks like? Read "Hot Lights, Cold Steel." Want to learn why orthopaedics treats fractures instead of general surgery (like in some countries, including the USA pre-WW2)? Read "Rearticulations of Orthopaedic Surgery." Really want to understand the concepts of reducing fractures, and learn from a legend at the same time? Read, "The Closed Treatment of Common Fractures" by Sir Charnley himself. Take an interest in the field you are passionate about, and you learn a lot while setting yourself apart.
