Where possible, the best results may be achieved by reattaching the amputated original tissues (microsurgical replantation). In noninfected, uncontaminated traumatic injuries resulting in composite soft tissue defects, Early free flap reconstruction of the upper extremities has important advantages over delayed (72 h-3 months) or late wound closure (3 months-2 years). In recent years, thin, pliable, and versatile fasciocutaneous flaps such as the anterolateral thigh (ALT) and lateral arm (LA) free flaps have been increasingly used with great success to reconstruct the upper extremity. The use of "spare parts" and functional reconstructions using osteomyocutaneous free flaps or toe to thumb transfers complete the armamentarium of the upper limb reconstructive microsurgeon.
