Abstract
ABSTRACT A captive adult male bush dog (Speothos venaticus) was referred to our Veterinary Medical Teaching Hospital from a local zoo due to a two-week history of progressive hind limb gait impairment and ataxia, non-responsive to clinical management. Computed tomography revealed decreased disc space at L3 - L4 level, with probable disc extrusion narrowing the right side of the spinal canal, compressing the spinal cord. We opted to surgically remove the disc material using both fenestration and right lateral pediculectomy (mini-hemilaminectomy) techniques. Twelve days after surgery there was mild residual proprioceptive ataxia. Gait was fully regained with remission of the neurological deficits around the 30th postoperative day. This is - to the best of our knowledge - the first successful report of a lumbar intervertebral disc extrusion in a bush dog (Speothos venaticus) surgically treated by pediculectomy and disc fenestration.
Highlights
The bush dog (Speothos venaticus) is a small canid - rarely seen in nature - from Central and South America (DeMatteo and Loiselle, 2008)
It’s vulnerability is due to the toll of human progress and urban expansion over what was once their natural habitat, lack of protective laws added up to their susceptibility to fall ill from domestic dog (Canis lupus familiaris) diseases (Oliveira and Dalponte, 2008)
Hemilaminectomy has been applied to a binturong (Arctictis binturong) (Spriggs et al, 2007), a lion-tailed macaque (Macaca silenus) (Capitanio et al, 2008) and tigers (KetzRiley et al, 2004; Flegel et al, 2008)
