[Surgical replantation]

In the early days of replantation surgery, if viability was restored the operation was judged a success. Nowadays restoration of viability alone is not sufficient to fulfill the criteria of successful replantation, which are as follows: Lack of severe systemic disturbances due to the replantation, a "functional extremity" according to the definition of Chen et al. (1978), no or little pain at the site of the replantation, good aesthetic results, and an acceptable length of time for rehabilitation and return to normal life. Successful replantation needs a therapy concept that is based on an exact definition of the amputation injury from the viewpoint of the amount of severance, the level of the amputation, and the type of amputation mechanism, complete knowledge of current replantation indications, and exact selection of patients amenable for replantation.
