Fibrin sealant in prevention of flexor tendon adhesions: an experimental study in the rabbit

The effect of fibrin sealant on the development of adhesions in flexor tendon surgery was studied in both immobilized and active weight-bearing paws of rabbits. A partial laceration was produced and was treated with sutures alone or with both sutures and glue. Immobilized tendons treated in these ways showed no difference in adhesion formation, but in mobile tendons there was a difference at 6 weeks in gross appearance, scanning electron micrographic appearance, and strength of adhesions as measured when the distally cut tendon was pulled out of its sheath. These observations indicate that, after repair, a mobile flexor tendon heals with a smooth gliding surface and without formation of restricting adhesions when treated with fibrin glue around the suture site.
