ABSTRACT
Reconstructive surgery is indicated after nerve palsy in the upper extremity once it is certain that nerve recuperation is impossible. In fact, the problem is complex because it is often difficult to determine precisely the likehood and quality of potential nerve regeneration. The situation was less trying some time ago, when the prognosis for recuperation after proximal nerve lesions was then so bad that one could advise tendon transfers at the time of nerve repair, almost without risk. 1 With progress in nerve repair, early tendon transfers are now seldom required.
