Topografia do cone medular de Ouriço-cacheiro (Coendou prehensilis, Linnaeus, 1758) (Rodentia)

The first proposed of caudal anesthesia was in 1926 and many techniques were developed to anesthetize the lumbar and sacral spinal nerves. This study determined the medullary cone topography of the Coendou prehensilis, using six adults from the Sabiá Park Zoo, Uberlândia-MG. The material was fixed in formaldehyde solution 10% in the LAPAS. The skin incision was done, then the spine muscles were removed and the vertebral arches were cut to visualize the spinal cord and the surrounding structures. The medullary cone in all the specimens began in the fourth lumbar vertebra (L4) and finished in the second sacral vertebra (S2), and the length changed to 5.9cm to 4.7cm. This study concluded that the best place for epidural anesthesia of the pelvic limb in the Coendou prehensilis is between the L4 and S2 vertebrae.
