Orthopedic surgery or orthopedics (also spelled orthopaedic surgery and 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, sports injuries, degenerative diseases, infections, tumors, and congenital disorders.
Doctors that specialize in this branch of medicine are called orthopedists or orthopedic surgeons, and they treat problems of the bones, joints, ligaments, tendons, muscles, and nerves.
Orthopedic surgeons treat a wide range of musculoskeletal disorders, like trauma (broken bones), sports injuries, degenerative diseases, back pain, congenital defects and tumors.
Procedures commonly performed by orthopedic surgeons include joint replacement surgery such as hip or ankle replacement, spine surgery, shoulder surgery, anterior cruciate ligament reconstruction and disc replacement surgery.
Orthopedic surgeons may sub-specialize in hand surgery, joint reconstruction, spine surgery, sports medicine and trauma.
