Orthopedic surgery or orthopedics (alternatively spelt orthopaedics) is the branch of surgery concerned with conditions involving the musculoskeletal system. Orthopedic surgeons use both surgical and nonsurgical means to treat musculoskeletal trauma, spine diseases, sports injuries, degenerative diseases, infections, tumors, and congenital disorders.

In the present book, ten typical literatures about orthopedic surgery published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on orthopedic surgery. We hope this book can demonstrate advances in orthopedic surgery as well as give references to the researchers, students and other related people.
