acute; pain, paresis, paralysis, ataxia, root signature
Lameness or pain in a limb due to nerve root compression.
On a radiograph, signs of IVDE may include __(2)__, but you need _________ to definitively diagnose IVDE.

Describe medical treatment of IVDE. (3)
rest, NSAIDs, muscle relaxants
Describe surgical management of IVDE and when it is warranted.
when unresponsive to medical treatment or neurologic deficits worsen; hemilaminectomy(thoracic or lumbar) or ventral slot (cervical) to remove material compressing spinal cord
With intervertebral disc protrusion (IVDP), the __________ and __________ degenerate and bulge into the spinal canal.

Large breed dogs
Describe the conservative treatment of IVDP.
