A successful replantation of mutilated extremities should have not only the certainty of survival but also the maximum functional recovery. In this study of 40 replantation units after more than 5 years’ follow-up only 70% achieved good or excellent result. Five cases failed in replantation due to wrong indication orthrombosis of vessels. The causes of unsatisfactory replantation were two level amputation, technical failure, infection and adhesion of tendons. Careful selection of patients, improved surgical skill, and good handling of tendons will surel improve the result of replantation in the future.
