What percent of disk cases does Cervical IVDD account for
20%
Signalment for cervical IVDD
3-8 yr Dach, Beagles, Poodle and Dobies due to primary disc dz

Also, lg breeds secondary to cervical vertebral instability
What is the difference in location for cervical IVDD based on breed size
Small breeds usually C2/3

Large breeds usually C 5/6 or C6/7
What is the difference b/t Type I and II disc dz
I- disk extrusion (aka chondroid degeneration) seen in chondrodystrophic breeds; disk loses water content, which decreases its pliability

II- disk protrusion; fibrous degeneration that occurs over a period of time
What are three factors that severity of disc dz depends on
Site of extrusion
Speed/Velocity of extrusion
Volume of disk extruded
What is the most common clinical sign of cervical IVDD
Neck pain
True/False: Large amounts of disc material extruded can cause cord compression and neuro deficits
True
Reflexes depend on segment affected
What is the definition of conservative therapy for cervical IVDD
Absolute cage rest
NSAIDs
Muscle relaxants (Valium OR Methocarbamol)
When is conservative tx appropriate in a case of cervical IVDD
If pain is the only presenting sign, and this is the first time
Why would a myelography/CT be indicated in patient w/ first time suspected IVDD
When conservative tx has not worked (strict cage rest for 7-10 days has not helped)
What is the most common clinical procedure for tx of cervical IVDD
Ventral slot decompression
What is a possible reason for a large amount of hemorrhage seen during a ventral slot
If disrupt vertebral sinus, bleeds a lot and cannot be ligated or cauterized!
What is the px for cervical IVDD patients that undergo sx
