Spinal Fractures and Luxations

Question 1

Vallefuoco, VCOT, 2014:

Short- and long-term outcomes in cats with T/L fracture-luxations treated with screws and PMMA?

Answer 1

Vallefuoco, VCOT, 2014:

50% excellent outcomes, 25% satisfactory outcomes, 25% died in the post-op period due to concomitant injuries

Question 2

Sturges, Vet Surg, 2016:

Lumbar vertebral stiffness and ROM following stabilization of lumbar vertebrae with bilateral pins + PMMA vs unilateral LCP?

Answer 2

Sturges, Vet Surg, 2016:

Lumbar vertebral stiffness was greater with bilateral pins + PMMA, and ROM was reduced with bilateral pins + PMMA, compared to unilateral LCP

Question 3

Di Dona, VCOT, 2016:
Percutaneous transilial pinning for L7 fractures

Outcomes?

Answer 3

Di Dona, VCOT, 2016:

88% good to excellent outcomes (normal function), 12% poor outcomes (persistent unilateral sciatic nerve deficits)

Question 4

Nel, Vet Surg, 2017:

Fixation of LS fracture-luxations with pins + PMMA or SOP plates provide similar stability - true or false?

Answer 4

Nel, Vet Surg, 2017:

True

Question 5

Tran, Vet Surg, 2017:
Lateral vs dorsal stabilization of lumbar spinal fracture-luxations

Advantages and disadvantages of the lateral approach?

Answer 5

Tran, Vet Surg, 2017:

Advantages: superior for pin angle accuracy and bone purchase - clinically important consequences of breach are less common
Disadvantages: prevents observation of the articular facets

Question 6

Fujioka, Vet Surg, 2019:
Patient-specific drill guide template

1. What % of screws were placed without vertebral canal invasion?
2. Was greater accuracy achieved for screws placed in the cranial lumbar or caudal thoracic vertebrae?

Answer 6

Fujioka, Vet Surg, 2019:

1. 90% of the screws were placed without vertebral canal invasion
2. Greater accuracy of screw placement was achieved in the cranial lumbar vertebrae than the caudal thoracic vertebrae

Question 7

Gallastegui, VRU, 2019:

What % of fractured vertebrae had complete agreement for exact fracture location between MRI and CT?

Answer 7

Gallastegui, VRU, 2019:

Complete agreement between MRI and CT was achieved in only 14-33% of fractured vertebrae

Question 8

Schmidli, VCOT, 2019:
C2 fractures

1. What % only showed cervical pain?
2. What % had fractures involving the dens?
3. Chances for full or functional recovery with conservatively vs surgically managed cases?

Answer 8

Schmidli, VCOT, 2019:

1. 32% showed only cervical pain
2. 23% had fractures involving the dens
3. Chances of full or functional recovery were very good for both conservatively and surgically managed cases

Question 9

Hansen, JVECC, 2019:
Traumatic AA subluxation

1. What % of cases had additional information about further injuries that were obtained only by CT or MRI?
2. Most common location for cervical fractures?

Answer 9

Hansen, JVECC, 2019:

1. 88%
2. Most common location for cervical fractures was the body of C2
