Objective Intervertebral disc fenestration has been shown to reduce the risk of extrusion in the thoracolumbar region in dogs, but use of the technique varies between individual neurologists and surgeons. Our aim was to investigate opinions and practices regarding disc fenestration amongst those involved in neurosurgery in dogs. null null null null Study Design A web-based survey containing questions relating to the use of fenestration during treatment of intervertebral disc extrusion in dogs was distributed to board-certified neurologists and surgeons. Results were analysed using Microsoft Excel. null null null null Results There were 323 responses from 190 neurologists and 133 surgeons. Seventy-one per cent of respondents routinely used concurrent disc fenestration when performing decompressive surgery in the thoracolumbar region, although the rate was lower amongst surgeons (55%) than neurologists (82%). Only 25% of respondents performed concurrent fenestration in the cervical spine. Forty-five per cent of respondents reported having experienced complications, with haemorrhage being the most common. null null null null Conclusion Fenestration is widely used in the management of thoracolumbar intervertebral disc extrusion, but a universally accepted approach does not exist, and differences are seen between neurologists and surgeons.
