Hand surgery, offered at Chattanooga, deals with diagnosing, prescribing medicines and therapy and generally caring for problems associated with the hand, wrist and forearm, along with diagnosing and caring for the shoulder and elbow. This field deals with both surgical and non-surgical treatments. This is usually practised by graduates in general surgery, plastic surgery and orthopedic surgery, who take the certificate examination of "Certificate of Added Qualifications in Surgery of the Hand" once they have the requisite qualifications. This practice is used for treating conditions such as hand injuries, carpal tunnel syndrome, carpometacarpal bossing, rheumatoid arthritis, Dupuytren's contracture and congenital defects. The surgeon, depending on his initial qualification, can operate for setting fractures, "replant" operations for injuries and trauma, and repair connections of tendon, muscle and bone. Thus, one should seek out hand surgery if one is experiencing pain and/or discomfort, at the places available in Chattanooga. Continuing medical education for practitioners of hand surgery is provided by associations such as the American Society for Surgery of the Hand and the American Association for Hand Surgery.
