This atlas presents a collection of richly illustrated teaching cases. It covers the fundamentals of orthopedic oncology complemented with relevant aspects that are demonstrated using individual cases. In a specialty that deals with a relatively smaller number of cases compared to tumors of other systems, this atlas prepares readers for clinical practice by combining a problem-based learning (PBL) approach, which lies on the continuum between structured and guided learning, with theory and practical insights. The book is divided into sections, arranged according to anatomical regions and the reconstruction type. Each section focuses on a specific anatomical region, and each case presentation includes the basic clinical history, basic principles, preoperative, perioperative and radiographic images, a pitfall list, treatment strategy, technical pearls, outcomes and complications. For each region the authors discuss both the biological and non-biological reconstruction techniques. The book is designed to actively involve the reader, making it an invaluable tool for all orthopedic surgeons confronted with oncologic surgery. The book is intended for trainees in orthopedics, orthopedic oncology fellows as well as practicing consultants.
