This book, published in January 2023, adopts an innovative approach to tackling the ST3 (Trauma and Orthopaedic Surgery) interview for securing a National Training Number in the UK National Health Services. It utilises an anatomic area-based approach which covers the relevant topics of anatomy, clinical stations, surgical approaches and operations. This aims to encourage the prospective applicant to consolidate his or her knowledge as he or she tackles each of the different stations in one anatomical area. ST3 Interview Preparation for Trauma and Orthopaedic Surgery book is intended to help prospective applicants to apply a systematic approach to clinical stations, and it provides a reproducible framework that can be applied to commonly asked questions. Each topic has a structured question-and-answer section to enable candidates to assess their knowledge. The scope of this book is to cover the clinical and technical skills stations of the interview, including orthopaedic-related knowledge and anatomy, relevant guidelines, surgical approaches, operations, and technical skills.
