The effect of butyric acid with autogenous omental graft on healing of experimental Achilles tendon injury in rabbits

In this study، the role of local injection of butyric acid (BA) with autogenous omental graft was evaluated in healing of experimental Achilles tendon injury in rabbits. Nine adult male New Zealand rabbits were anesthetized and a partial thickness tenotomy was created on both hindlimbs. In treated group، omental graft was secured in place using BA soaked polygalactin 910 suture. In control group، the graft was sutured without BA. Butyric acid and normal saline were injected daily to treatment and control groups for three days، respectively. Based on the findings، on day 15 after injury، the tendon sections showed that healing rate in BA treated group was higher than that in control group. Furthermore، at days 28 and 45، comparison between BA treated and control groups demonstrated that BA increased the healing rate but with no significance. In summary، results of this study show that application of BA with autogenous omental graft can improve healing process of damaged Achilles tendon.
