Homologous vessel graft as substitute for flexor tendon graft. An experimental study on rabbits

Homologous vessel grafts were tried as substitutes for flexor tendon grafts. Pieces of different lengths were excised from a flexor tendon and replaced by a homologous abdominal aorta graft which was turned inside out and then anastomised by drawing it over the tendon stumps in a cuff-like manner. The grafts became firm, homogeneous and completely tendon-like with very little adhesion but with a tendency to become extended and thus too long to be functional.
