[Problems of the two-stage restoration of flexor tendon injuries. I. Current results. Biological and functional factors affecting healing].

After describing the morphological and biological relations in the intact human flexor tendon and tendon sheat unit authors deal in details with the severe injuries of the flexor tendons inside the tendon sheat, having a bad prognosis. The results of the previous experimental investigations, and among them their own results, are reviewed. The success of the two-phase tendon transplantations in this kind of injury is determined, according to their opinion, beside the known clinically related factors, by biological and functional factors. Further examination of the complicated reparative processes with the use of modern methods of investigation is planned. The present work is ment for introduction of these experiments.
