Abstract:
PURPOSE: Peritendinous adhesion is one of the most notorious complication after the flexor tendon injury. In this study, Alloderm(R)(LifeCell Corp., Branchburg, N.J.), which is the decellularized human dermal analogue with its intact native basement membrane components, was used for the prevention of peritendinous adhesions following flexor tendon repair. METHODS: Thirty New Zealand white male rabbits were divided equally into 3 groups. In all groups, the flexor digitorum profundus of the third finger of the right back foot was cut totally and repaired by modified Kessler suture technique. Following tendon repair, Alloderm(R) was wrapt around the repaired tendon in the first group and sodium hyaluronate gel was sprayed to the operation field in the second group. In the control group, no external material was applied. The right back foot were immobilized for 6 weeks to optimize the formation of adhesion ingrowth. After death, the third finger that repaired tendons and sheaths was removed en bloc. We checked range of motion. and studied histologically for all groups. RESULTS: The experimental groups had better range of motion than the control group. We checked that the range of motion was 73.5 degrees in Alloderm(R) group, 55.9 degrees in the hyaluronic acid group, and 38.3 degrees in the control group. in the histological study, the experimental group had less adhesions compared with the control group. CONCLUSION: This study concludes that Alloderm(R) can decrease peritendinous adhesions following flexor tendon repairs in rabbits. We think the method could be used in clinical cases.
