The hand is the most complex and versatile structure in the human body. Formed of 27 bones, the hand and wrist require more than 30 muscles and a vast web of ligaments and tendons to move them into the myriad postures required for the countless tasks the hand performs every day. The complexity of hand function is reflected by the large amount of brain space dedicated to it. Injury to or dysfunction of any element of hand function can cause significant disability. Because of the importance of the hand to every aspect of life, it is essential for the surgeon to make the correct diagnosis and perform the appropriate and needed procedures, avoiding both undertreatment and overtreatment.
