The objective of this experiment was to document the postoperative evolution of New Zealand rabbits that underwent a hemi laminectomy surgery (T13-L1) and received a graft of autogenous muscle as an hemostatic agent into the spinal canal. These animals were followed for a period of 14 and 28 days with daily neurological assessments and, at the end of their follow-up period, were euthanized in order to remove the graft site to be examined microscopically. The animals were divided into 6 groups such as the control group A and B, C and D treated with 25% decrease of the medullary canal and, E and F treated with 50% decrease of the medullary canal. All groups were evaluated neurologically every day until euthanasia. Groups A, C and E were euthanized at 14 days after the surgery and groups B, D and F at 28 days. The segments T11-L3 vertebral column of all the rabbits were collected and sent for histopathological examination. In order to evaluate the neurological postoperative effect, the animals were classified daily by the Tarlov scale and the results were compared by nonparametric Kruskal-Wallis test for each time (days). There was no statistical difference among the groups. Histopathological examination showed the presence of muscle grafted in the spinal canal and the spinal cord compression caused by the graft.
