Orthopedic surgery deals with problems of the spine and the extremities. An orthopedic surgeon diagnoses and treats patients whose musculoskeletal problems include arthritis, trauma and congenital deformities. He or she also works with patients who have traumatic and overuse injuries. Using both surgical and non-surgical means, the orthopedic surgeon will treat injuries and degenerative problems of the spine and extremities, such as hands, feet, knees, shoulders and elbows.
