Current concepts of digit replantation.

Amputated or devascularized digits should be appropriately cooled as quickly as possible. The injured extremity is dressed, splinted and elevated. Careful selection of patients for replantation has yielded satisfying results to both patients and surgeons. Replantation is indicated for a thumb or multiple-digit amputation or proximal-level injuries. However, single-finger replantation (except in a child or when extenuating circumstances exist) may not be warranted. Success depends on function, not merely on making the digit viable.
