Hand Surgery

About Hand Surgery

The hand is one of the most complex parts of the human body. Bones, joints, muscles, nerves, blood vessels, and skin are concentrated within a small area, allowing the hand to function as both a highly precise organ of movement and an important sensory organ. Because these structures work closely together, they cannot always be considered or treated separately.

The hand also contains many joints of different types. Hand problems may result from injuries and musculoskeletal disorders, as well as medical conditions such as rheumatoid arthritis and conditions associated with menopause. The wide range of possible injuries and disorders means that specialist knowledge is often required for accurate diagnosis and treatment.

Hand surgery is therefore recognized as a specialist field within Japan’s medical certification system. Some of the main conditions treated by hand surgeons are listed below. The list is based in part on information published by the Japanese Society for Surgery of the Hand.
