A Guide to Xrays (PART I) - The Ankle Joint

A Guide to X-rays in Orthopaedics – Part I: The Ankle Joint is a practical and visually driven guide to understanding and interpreting ankle radiographs. Designed for medical students, orthopaedic residents and practising clinicians, the book focuses on developing a systematic approach to reading X-rays rather than simply memorising findings. It explores the AP, mortise and lateral views in detail, explaining positioning, adequacy, normal anatomy and the important parameters that should be assessed. Readers are guided through concepts such as medial clear space, tibiofibular overlap, tibiofibular clear space, talar alignment and ankle mortise congruity. The book also explores useful findings on the lateral radiograph, including Kager's fat pad, Böhler's angle, Gissane's angle and calcaneal alignment. Important special projections and functional radiographs are introduced to demonstrate how additional views can answer specific clinical questions. Illustrations, annotated radiographs and concise explanations are used throughout to make complex radiographic concepts easier to understand and remember. Rather than treating measurements as absolute diagnostic cut-offs, the book encourages readers to interpret them alongside radiographic appearance, clinical examination and the overall patient picture. The aim is to help readers recognise not only obvious fractures but also the subtle changes in alignment, relationships and spaces between bones that may reveal an important injury. Ultimately, this book teaches you where to look, what to look for, and how to think about what you see on an X-ray.
