Abstract

In order to determine the best location for performing the technique of epidural access either to epidural anesthesia, myelography scans, spinal tap, among others, this study aimed to describe the anatomy of the conus of the crab eating fox (Cerdocyon thous), particularly its esqueletopia. For the realization of this work six adult animals of both sexes were dissected, withdrawing from the muscles of the lumbar and sacral vertebrae column to identify, removing the muscles of the lumbar and sacral vertebrae column to identify which were sectioned in their vertebral arches to expose the spinal cord. Medullary cone was identified, measured with a pachymeter and identified its esqueletopia. In all animals studied, the presence of seven lumbar vertebrae (L) were observed. Showed the conus with the base in L5 (50% of animals), or between L5 and L6 (50%) in the apex L6 (66.7%) between L6 and L7 (16.7%) or in L7 (16.7%). The average length of the medullary cone observed was 16.62 + 7.33 mm. As the apex of the conus does not exceed the lumbosacral space. We concluded that this space is possible the realization of access to the epidural space without risk of injuring the spinal cord of the animal.
