Replantation in the lower leg, although technically feasible, still remains a complicated clinical issue in terms of the decision-making process. In children, a limb salvage or replant procedure would seem preferable; however, in crush amputations from railroad injury, a very severe trauma, difficulties in treatment should be thoroughly weighed against prosthetic possibilities: for example, only a fair or good functional outcome would justify an attempt to replant a severed shin. Unfortunately, the outcome in most cases is unpredictable at the time of initial evaluation, and even during the replantation procedure itself. To facilitate prognosis, the authors determine four typical variants of replantation course and outcome, based on local patient conditions, although they stress that no clear indications for replantation vs. prosthesis can be derived from the variants listed. Rather, general guidelines for the surgeon's decision at a very early stage of treatment are presented. Choice of procedure and tactics cannot be determined once and for all, because the prognosis for functional outcome can change during the course of treatment. Among a few well-defined situations are clean amputations (replantation is indicated) and traumas with very extensive crushing of the whole lower leg (replantation is contraindicated). In the majority of cases, replantation is a worthwhile attempt, but this does not imply that a replanted extremity must be preserved at any cost. The surgeon must consider the possibility of re-amputation, in case of an unfavorable variant in the postoperative course. A successful case of replantation, involving two lower leg railroad amputations in a child, is presented.
