World Clinics in Orthopedics is intended as a practical resource for both orthopedic surgeons in practice and in training. It is a detailed overview of the newest information in the field of orthopedics, arranged by subspecialty.

We have sought to provide the reader with the most pertinent and recent developments written by thought leaders in each of the major orthopedic subspecialties: spine, hip preservation, hip and knee arthroplasty, sports medicine, shoulder and elbow, foot and ankle, hand and wrist, oncology, trauma, pediatrics, and basic science. Furthermore, we are excited to have contributions from internationally renowned surgeons in Europe, Asia, and Central and South America. This lends a truly international perspective to this work and alerts the reader to challenges faced by surgeons the world over.

It is our sincerest hope that World Clinics in Orthopedics will serve as a compendium of the newest in orthopedic knowledge. We hope that you, the reader, will find this as a unique, practical source for the latest information as you care for your patients.
