Progress in limb and digital replantation: Part B.
Progress in micro- or macroreplantation has resulted in higher survival rates of formerly amputated parts. Progress has been made as a result of intensive laboratory training and considerable experience due to the popular application of microsurgical techniques. More amputated digits or limbs may survive because the time of ischemia can be exceeded in using cold storage or perfusion. Homo- or heterodigital vessel transposition, expanded indications for vein graft interposition, as well as heterotopic transplantation allow for extremity preservation even in crush injuries, and in disastrous multiple amputations combined with contusion or avulsion. Nowadays, microvascular digital replantation with vessel anastomosis distal to the distal interphalangeal joint in adults is technically feasible. Finger amputations in children are a prime indication for replantation. Maintenance of extremity length is possible in applying external fixation. Emergency free flaps or compound tissue transfer under the "Urgence differée" condition may provide reliable soft tissue coverage. Secondary reconstruction with regard to bone defects, tendon repair, and eventual nerve grafting have to be aspired, finally leading to an improvement of functional results in daily and leisure activities as well as in early professional readaptation.
