This book presents cases on the musculoskeletal system in clinical vignette format. Each case pertains to a specific diagnosis, and all cases are grouped according to the body region involved. It is our intention to present each case in a clear, concise, informative, and user-friendly manner. The purpose of this book is to provide medical students, PMR residents and young PMR attending preparing for their boards with a valuable resource for review, studying, and learning. We hope that we have succeeded in our goals, and that this book meets your educational needs.
