The repair of injuries to the nerves and tendons of the hand, with any reasonable assurance of success, is a product of modern aseptic, atraumatic surgery. With an increasing appreciation of wound healing and the many factors which affect it has come the realization that man is dependent for repair on living, healthy cells and that no amount of technical skill or rapid operating dexterity can compensate for disregard of delicate living tissue. Important in all surgery, this realization is doubly so in repair of the nerves and tendons of the hand, for in few situations do even minor disturbances of a wound play such havoc with end results. The first prerequisite for this type of surgical intervention is an appreciation of just what is meant by primary healing, since without this and without the patience to work carefully to attain it the end results will always be disappointing.
