83 children with 109 injuries to flexor tendons were re-examined according to the Buck-Gramcko scheme. On the basis of this, we can say that surgery to the flexor tendons in children gives better results than in adults. In pre-school children there can be widely differing results, since the necessity of post-operative care is not appreciated. These results could certainly be improved by painstaking care on the part of the doctor, combined with therapy in the hands of specially trained personnel and corresponding inclusion of the mother. In no case could be observe any disadvantage to the further growth of the hand bones, after surgery to the flexor tendons, including transplantation of a flexor tendon. Generally speading speaking, there appear to be no contraindications in children, as long as general principles are observed. In about one-third of the cases, a further improvement in function of the flexor tendor can be gained by secondary tenolysis.
