Q

Golini, Vet Surg, 2014:
Transarticular fixation combined with dorsal laminectomy and partial discectomy

  1. What % showed clinical improvement?
  2. Implant failure rate?
  3. Was arthrodesis of the articular facets observed?
A

Golini, Vet Surg, 2014:

  1. 76% showed clinical improvement
  2. 30% implant failure rate - post-op residual mobility of the LS joint may explain the relatively high implant failure rate
  3. Arthrodesis of articular facets was not observed in any dog

Q

Mackenzie, VRU, 2016:
Injected gelified ethanol into the LS disc

What % showed leakage of the injected material into the vertebral canal immediately after injection and at 1 year after injection?

A

Mackenzie, VRU, 2016:

33% showed leakage immediately after injection, 11% showed leakage at 1 year following injection

Q

Worth, Vet Surg, 2017:

  1. Dorsal annulectomy combined with partial discectomy may lead to further dynamic collapse of the LS articulation - true or false?
  2. What is a possible cause for persistent or recurrent clinical signs of L7 nerve root compression?
A

Worth, Vet Surg, 2017:

  1. True
  2. Subsequent loss of foraminal volume could further compromise the LS intervertebral foramina during extension, resulting in persistent or recurrent clinical signs of L7 nerve root compression

  1. Results of the procedure?
  2. What % had a tense gait or stiffness while rising and sitting immediately post-op?
A

Muller, Vet Surg, 2017:

Q

Saunders, Vet Surg, 2018:

  1. Was there an association between a greater rostral projection of the sacral lamina and a diagnosis of DLSS?
  2. Is the height of the vertebral canal at L7/S1 diagnostic or predictive of DLSS?
  3. Risk factor(s) for development of cauda equina syndrome?
A

Saunders, Vet Surg, 2018:

  1. No association between greater rostral projection of the sacral lamina and DLSS
  2. Height of the vertebral canal at L7/S1 was neither diagnostic nor predictive of DLSS
  3. Dogs >5 years of age had a greater risk of developing cauda equina syndrome

Q

Zindl, Vet Surg, 2018:
Pedicle screw-rod fixation system

Effect(s) on motion at L7-S1 and L6-7?

A

Zindl, Vet Surg, 2018:

Significantly reduced primary and coupled motion at L7-S1 with a concomitant increase in motion at L6-7, which may suggest the potential for adjacent level effects

Q

Worth, VCOT, 2018:

  1. Effect(s) of lateral foraminotomy on volume of the LS lateral intervertebral neurovascular foramen?
  2. Regrowth of bone at the foraminotomy site occurred despite having excellent outcomes - true or false?
  3. Increased foraminal volume was still evident at long-term follow-up, but in 33% of those dogs, what was the % increase in foraminal volume compared to pre-op?
A

Worth, VCOT, 2018:

  1. Lateral foraminotomy increased the volume of the LS lateral intervertebral neurovascular foramen to >7 times its initial volume
  2. True
  3. In 33% of the dogs, the long-term increase in foraminal volume was only 125% of the pre-op volume
