Regarding the complexity of healing tendon and the factors that interfere with this, the aim of this study was to evaluate the comparison between the suture materials. Canine flexor digitorum profundus (FDP) tendons were collected from nine healthy mongreal adult dogs. The 18 thoracic FDP were randomly selected in three groups of tendons submited of tenotomy and tenorraphy using Prolene®, Nylon® e Vicryl®. The diameter 6.0 for epitendon and 4.0 for endotendon. The tendons were then repaired using one of suture material with the modified Kessler technique. The study was divided in two ensays. Ensay1: The tendons repaired were tested in Assay Universal Machine and were evaluate the biomechanical properties refering to Maximum Limit (ML), Elasticity Limit (EL), Rigidity (RG) and Resilience (RS). Ensay2: Prolene®, Nylon® e Vicryl® 6.0 and 4.0 size were tested alone. Although Vicryl® it has been the more rigid suture material, this revealed to be the most appropriate thread for the experimental tenorrafia in dogs, because among all the other appraised mechanical properties it was what obtained the best results.
