<unk> s are a<unk> s specializing in the care and treatment of problems relating to the<unk> , wrist, and forearm including trauma and<unk>  infection.  Many<unk> s also treat the elbow, arm and shoulder.<unk> s do not just engage in surgery - they are the primary medical doctors to deal with these issues, and often use non-surgical approaches.
In the US,<unk>  surgery is a subspecialty of surgery.  A<unk>  must first qualify as a general<unk> , plastic<unk> , or orthopedic<unk> , and then must do a one year long fellowship in<unk>  practice.  Board certified general, plastic, or orthopedics<unk> s who have completed approved fellowship training in<unk>  surgery and have met a number of other practice requirements are qualified to take the "Certificate of Added Qualifications in Surgery of the<unk> " examination, commonly referred to as the "CAQSH."
The historical context for the three qualifying fields is that both plastic surgery and orthopedic surgery are more recent branches off the general surgery main trunk.  Modern<unk>  surgery began in World War II as a military planning decision. US Army<unk>  General, Major General Norman T. Kirk, knew that<unk>  injuries in World War I had poor outcomes in part because there was no formal system to deal with them. Kirk also knew that his civilian general surgical colleague Dr. Sterling Bunnell had a special interest and experience in<unk>  reconstruction. Kirk tapped Bunnell to train military<unk> s in the management of<unk>  injuries to treat the war casualties, and at that time<unk>  surgery became a formal specialty. Orthopedic<unk> s continued to develop special techniques to manage small bones, as found in the wrist and<unk> . Pioneering plastic<unk> s developed microsurgical techniques for repairing the small nerves and arteries of the<unk> s from all three specialties have contributed to the development of techniques for repairing tendons and managing a broad range of acute and chronic<unk>  injuries.<unk>  surgery incorporates techniques from orthopaedics, plastic surgery, general surgery, neurosurgery, vascular and microvascular surgery and psychiatry and is a complex, fascinating specialty.
Two medical societies exist in the United States to provide continuing medical education to<unk> s: the American Society for Surgery of the<unk>  and the American Association for<unk>  Surgery.
