Reinervation techniques can be done by termino-terminal or end-to-side anastomosis, and it has been extensively studied. The end-to-side anastomosis hasn’t been used often compared to the termino-terminal technique, because the former is contested by some authors regarded the reinervation chances when the integrity of the epineuro is maintened. Therefore, due to the divergenses, the authors decide to study the effects of epineuro in the nervous regeneration in the end-to-side anastomosis technique. In this study, 20 wistar adults rats were used, distributed in two groups (A and B). In the A Group, 10 rats were submited to the section of fibular nerve in the right pelvic limb and fixation of this nerve to the muscle; in the left pelvic limb, section of the fibular nerve was done with lateral anastomosis with the fibular nerve. In Group B, the procedures were indentical to the A group, with the only difference that the limbs were exchanged. In the 90 th post operative day a biopsy was performed in each fibular nerve in order to histological analisys in optical microscope, where the reinervation was object of study. The reinervation was found happened, showing that the preservation of epineuro didn’t avoid the axonal regeneration.
