Hand surgery encompasses a broad range of procedures to restore function and appearance of the hand following trauma, infections, congenital deformities, or rheumatic changes. Common types of hand surgery include skin grafts, tendon repairs, nerve repairs, joint replacements, and replantation of amputated fingers or hands using microsurgery. Risks of hand surgery depend on the procedure but can include infection, incomplete healing, loss of movement or feeling in the hand or fingers, and blood clots.
