Reimplantation remains the reference treatment for functional and aesthetic recovery of the hand. The interest of this study is to propose the reposition flap as an alternative to different hedging techniques in the proximal stump, in many situations where revascularization is impossible. It consists in osteosynthesis of the bone fragment and its coverage by a pedicled local flap. Methods： The technique of reposition flap was evaluated retrospectively between 2003 and 2016 through a study of 13 patients compiled in Nabeul orthopedic department. For each patient, the sensitivity, the pulp trophicity, the interphalangeal mobility, the digital length, the appearance of the nail and radiological consolidation were evaluated. Results： The reposition flap keeps more than 80% of the length of p3. This procedure improves nail aesthetics in comparison with the regularizations. There is no significant difference in sensitivity of the pulp or of the mobility of the distal inter-phalangeal （DIP） joint as a function of the technique studied. However there is a significant difference in average test of the Quick Dash （350 against 500 for regularizations）. Conclusion： The reposition flap seems to be a good alternative to regularization in the context of trans-p3 fingers amputations, in which the distal fragment is not revascularizable. It allows better aesthetic and functional results.展开更多
