Effect of Amniotic Membrane Transplantation on Tissue Adhesion in Flexor Tenorrhaphy of Chicken / 대한정형외과학회잡지

ABSTRACT

PURPOSE: The role of the amniotic membrane with or without radiation was investigated with regard to preventing adhesion after flexor tenorrhaphy of chicken. MATERIALS AND METHODS: Nine chicken were divided into three groups. The second flexor tendon of the chicken was operated on. In group A, the flexor tendon was excised and one half and the tendon was repaired. In group B, the repaired tendon was covered with an amniotic membrane. In group C, the repaired tendon was covered with a lyophilised and 25 kGy irradiated amniotic membrane. The gross and histology findings on the level of inflammation and fibrosis of the repaired tendon were evaluated at 3, 6 and 9 weeks after surgery. RESULTS: Group C had the least inflammatory cell infiltration and fibroblast proliferation at any time. CONCLUSION: The use of radiated amniotic membrane was effective in preventing inflammation and adhesion after flexor tenorrhaphy in chickens.
