The hand is a very complex organ with multiple joints, different types of ligament, tendons and nerves. With constant use, it is no wonder that hand disease injuries are common in society. Hand injuries can result from excessive use, degenerative disorders or trauma. Trauma to the finger or the hand is quite common in society. In some particular cases, the entire finger may be subject to amputation. The majority of traumatic injuries are work-related. Today, skilled hand surgeons can sometimes reattach the finger or thumb using microsurgery. Sometimes, traumatic injuries may result in loss of skin, and plastic surgeons may place skin and muscle grafts.
