Noyes, Vet Surg, 2017:
Planned laminectomy defects tended to be larger based on MRI compared to CT
Castel, JVIM, 2017:
- What % of the cases that developed PMM did and did not have intact pain perception at presentation?
- IVDD at what location has increased risk of developing PMM?
Castel, JVIM, 2017:
- 25% of PMM cases had intact pain perception and 75% did not
- Mid-lumbar IVDDs are at increased risk of PMM
Chai, JAVMA, 2018:
What was associated with increased odds of IVDD in Pekingese?
Chai, JAVMA, 2018:
Presence of calcified discs in the T10-L4 region, greater body weight, and female dogs
Hamilton-Bennett and Behr, Vet Surg, 2019:
Cats with IVDD treated with hemilaminectomy
- What outcomes were achieved?
- What % had dispersal of extruded disc material beyond the disc space evident on MRI?
- What % had complete degeneration of the extruded disc and lateralization of the extruded disc material?
Hamilton-Bennett and Behr, Vet Surg, 2019:
- 50% excellent outcome, 17% good outcome, 17% poor outcome
- 83% had dispersal of disc material beyond the disc space
- 50% had complete degeneration of extruded disc and lateralization of disc material
Gordon-Evans, Vet Surg, 2019:
What is associated with a slower recovery post-op in Dachshunds that receive post-op rehab?
Gordon-Evans, Vet Surg, 2019:
Increased pre-op disability is associated with slower recovery but not body condition
Moissonnier, VCOT, 2014:
Disc fenestration and intervertebral body spacer at C6/7
- Recommended size of spacer?
- Effects of disc fenestration and spacer placement on extension-flexion ROM?
Moissonnier, VCOT, 2014:
- Diameter of spacer should be 50% of the vertebral endplate width measured on VD radiographs and 50% of the vertebral endplate height measured on lateral radiographs
- Disc fenestration increases extension-flexion ROM, spacer placement decreases ROM in flexion but not extension
Hakozaki, JAVMA, 2015:
- Most common site of cervical IVDD in chondrodystrophic vs non-chondrodystrophic breeds?
- Most common site of cervical IVDD in Yorkies and CHH?
- Yorkies vs Dachshunds - which breed had higher numbers of affected discs?
- Was mean recovery time longer in dogs with 3 affected discs or 1 affected disc or neither?
Hakozaki, JAVMA, 2015:
- C2-3 in chondrodystrophic breeds, C4-5 in non-chondrodystrophic breeds
- C5-6 and C6-7 (54% of Yorkies and 69% of CHH)
- Yorkies had higher number of affected discs than Dachshunds
- Mean recovery time was longer in dogs with 3 affected discs than 1
Rossetti, Vet Surg, 2016:
Use of VITOM for ventral slot
- Most common site of cervical IVDD?
- What % had residual post-op extradural compression?
- What % had sinus bleeding?
Rossetti, Vet Surg, 2016:
- C2-3 (40%), C3-4 (33%)
- 57% had residual compression post-op
- 20% had sinus bleeding
Hermann, VCOT, 2018:
Standard ventral slot vs inverted cone slot vs slanted slot vs fenestration
- Which procedure(s) increased the ROM of the C4-5 VMU?
- Do the inverted cone slot and slanted slot provide any biomechanics benefit over the standard ventral slot?
Hermann, VCOT, 2018:
- All procedures increased the ROM of C4-5 VMU
- No benefit over standard ventral slot
Aikawa, Vet Surg, 2014:
- Proximity of the kyphotic segment from the site of IVDD in Frenchies?
- Risk of PMM in grade 5 Frenchies vs Dachshunds?
- What % of grade 5 Frenchies vs Dachshunds recovered?
Aikawa, Vet Surg, 2014:
- Sites of IVDD in Frenchies were 2-10 discs away from the kyphotic segment
- Disk of PMM higher in Frenchies than Dachshunds (33% of Frenchies vs 12% of Dachshunds)
- 33% of grade 5 Frenchies recovered vs 53% of grade 5 Dachshunds recovered
Salger, Vet Surg, 2014:
Thoracolumbar partial lateral corpectomy for IVDD
Main complications?
Salger, Vet Surg, 2014:
Hemorrhage (25%), nerve root injury (8%)
Steffen, JAVMA, 2014:
What is the suggested mechanism of functional improvement in dogs with IVDD treated conservatively?
Steffen, JAVMA, 2014:
Spontaneous regression of disc extrusions resulting in substantial reduction in size of herniated material, as well as functional compensation of neurologic deficits caused by spinal cord compression and decrease in inflammation
Rohner, VCOT, 2015:
Decrease in multifidus muscle blood flow was greater which which retractor - Gelpi or Grevel?
Rohner, VCOT, 2015:
Decrease in blood flow was greater with Gelpi retractors
