Orthopedics is a specialty within surgery, dealing with bone and soft-tissue disease, damage, and deformity. Its name derives from 17th-century treatment designed to produce "straight children." Until the advent of anesthetics, asepsis, and X-rays in medicine, its methods were restricted to amputation and manipulation for dislocation, etc. Treatment of congenital deformity; fractures and tumors of bone; osteomyelitis; arthritis, and joint dislocation are common in modern orthopedics. Methods range from the use of splints, physiotherapy, and manipulation, to surgical correction of deformity, fixing of fractures and refashioning or replacement of joints. Suture or transposition of tendons, muscles, or nerves are performed.
