Tendon and fascia transplantation for repairing flexor tendon

In order to explore the treatment methods of the injured frexor tendon in "no man’s land", we used chicken’s toe as the expermental model and transplanted tendon with its surrounding fascia to repair the defective profoundus tendon and sheath. Postoperatively, the animals were divided into motion and immobilization groups. Observaing the pathological changes under light and objective or electronic microscope, we found that early postoperative motion promoted the proliferation of repair cells and reduced adhesion. Excursions of the injured or transplanted tendon in the sheath repairing or mobilization group were better than in the sheath defect or immobilization group. Mechanical property of the grafted tendons provided the same difference.
