An experimental study of absorbable membrane in prevention of tendon adhesion in chicken / 中华创伤骨科杂志

ABSTRACT

Objective To investigate the effect of absorbable membrane on prevention of tendon adhesion after the ruptured tendon is repaired. Methods In our experiment, 30 12-weeks-old Leghorn cocks were divided into 2 groups randomly. Group A was the blank group, and Group B was the absorbable membrane group. Each group had 15 cocks. The flexor tendon of third phalanx was made ruptured. After repairing, histological observation, failure mode test and functional recovery test were performed regularly. Results In Group B, there was little adhesion between tendon and normal tissue under gross observation. There was no significant tissue necrosis or scar tissue under microscope. There was no difference in the failure mode test between the 2 groups 6 weeks after repairing. The functions of movement of interphalangeal and metacarpophalangeal joints in group B were better than those in group A. Conclusion The absorbable membrane can be a kind of material or method used to prevent tendon adhesion.
