Consequences of intraoperative spinal cord manipulation in dogs with thoracolumbar intervertebral disc extrusion
ABSTRACT The objective of the present study was to evaluate if extradural contact during hemilaminectomy would cause neurological deterioration in the early and/or late postoperative period in dogs with intervertebral disc extrusion. Nineteen dogs with thoracolumbar intervertebral disc extrusion und...
