for repairing tendons and managing a broad range of acute and chronic hand injuries. Hand surgery incorporates techniques from orthopaedics, plastic surgery, general surgery, neurosurgery, vascular and microvascular surgery and psychiatry. A recent advance is the progression to 'wide awake hand surgery.' In a few countries such as Sweden, Finland and Singapore, hand surgery is recognized as a clinical specialty in its own right, with a formal four to six years hand surgery resident training program. Hand surgeons going through these programs are trained in all aspects of hand surgery, combining and mastering all the skills traditionally associated with "Orthopedic hand surgeons" and "Plastic hand surgeons" to become equally adept at handling tendon, ligament and bone injuries as well as microsurgical reconstruction such as reattachment of severed parts or free tissue transfers and transplants. Scope of field Hand surgeons perform a wide variety of operations such as fracture repairs, releases, transfer and repairs of tendons and reconstruction of injuries, rheumatoid deformities and congenital defects. They also perform microsurgical reattachment of amputated digits and limbs, microsurgical reconstruction of soft tissues and bone, nerve reconstruction, and surgery to improve function in paralysed upper limbs. There are two medical societies that exist in the United States to provide continuing medical education to hand surgeons: the American Society for Surgery of the Hand and the American Association for Hand Surgery. In Britain, the medical society for hand surgeons is the: British Society for Surgery of the Hand (BSSH). In Europe, several societies are brought together by the Federation of European Societies for Surgery of the Hand (FESSH).
