Orthopedic Surgery 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. The word Orthopedics comes from two Greek words, ortho, meaning straight and pais, meaning child. Originally, orthopedic surgeons dealt with bone deformities in children, using braces to straighten the child's bones. With the development of anesthesia and an understanding of the importance of aseptic methods in surgery, orthopedic surgeons extended their role to include surgery involving the bones and related nerves and connective tissue.
