Case Studies: Neuro Surgery – Disc disease

Hemilaminectomy for disc disease after plain CT

A 9kg, Sealyham Terrier presented with acute paraplegia (paralysis of the hind limbs). The condition was painful, and there was still enough nerve connection between drain and feet to allow some response when the toes were pinched. Tail and hind limb reflexes were intact. Hind limb muscle tone was increased. Neurological signs localised to between...

Disc disease occurs when pathology affects the intervertebral discs – the soft tissue spacers that are found between vertebrae of the spinal column. The intervertebral discs are a bit like donuts with a fibrous surround (the annulus fibrosus) and a gel centre (the nucleus pulposus). Nerve roots come out between vertebrae and these can easily be...

These had progressed in the previous weeks and months, and at presentation to us the patient was knuckling on both back legs and looked “drunk”.

He was completely off his back legs and the referring vet suspected that one of the intervertebral discs, the soft tissue spacers that sit between the bones of the spinal column, had ruptured. One of our nurses recognised this dog and its...

Extruded disc material located centrally at L5-6

Intervertebral discs are the soft tissue structures separating the bones of the vertebral column. There are 7 cervical, 13 thoracic, and 7 lumbar vertebrae. Most clinically significant disc disease affects the thoracolumbar discs between T10 and L3. Degenerate discs can rupture and spill their central contents (disc extrusion) or bulge out (disc protrusion). The extrusion or protrusion...
