Question 1

Dejardin, Vet Surg, 2018:
Minimally invasive lag screw fixation of SI luxation/fracture using the Sacroiliac Luxation Instrument System (SILIS)
What was the dorsoventral and craniocaudal screw deviation from an ideal trajectory?

Answer 1

Dejardin, Vet Surg, 2018:
0.9-3.8 degrees deviation from ideal trajectory

Question 2

Pratesi, VCOT, 2018:
Bilateral SI luxation
How was SI reduction and stabilization achieved?

Answer 2

Pratesi, VCOT, 2018:
Use of a single 2.7mm cortical self-tapping transsacral screw and nylon nut

Question 3

Schmierer, Vet Surg, 2019:
Feline ilial fractures - single locking plate vs single non-locking plate vs double non-locking plate
Which implants withstood more cycles?
Screw loosening occurred in which constructs?
Which constructs were superior?

Answer 3

Schmierer, Vet Surg, 2019:
Locking implants withstood more cycles
Screw loosening occurred only in the non-locking constructs
Single locking constructs were superior to single non-locking constructs, but double non-locking constructs offered a strong alternative

Question 4

Guthrie
TPLO plate for ilial body fx
JSAP 2018

Answer 4

Reduction in pelvic canal diameter 5%

Question 5

Bourbos
Skeletal Traction for Pelvic Fx
VCOT 2021

Answer 5

Relationship b/w weight and traction of 2 cm
~Transverse linear
~Oblique square of body weight

Question 6

Jones
Influence of radiograph position on SI and LS angle
VCOT 2018

Answer 6

More than 5 degrees of malposition
~decreases SI and LS angles

Moving focal point to the femur
~decreased the measured lumbosacral angle

Abdominally centered radiographs
~no effect on lumbosacral and sacroiliac angles
