Question 1

Hanlon, vet surg 2022
Mechanical evaluation of canine sacroiliac joint stabilization using two short screws

-what length of the sacral body did the short screws span?
-which construct was stiffer?

Answer 1

23%
2 screws >2x yield load, stiffness

Question 2

McCarthy vet surg 2022
Accuracy of a drilling with a custom 3D printed guide or free-hand technique in canine experimental sacroiliac luxations

-% sacral corridor disruption in free hand?

Answer 2

20%

Question 3

Petrovsky, vet surg 2021
Short-term outcomes of 59 dogs treated for ilial body fractures with locking or non-locking plates

• What % non locking constructs had implant failure?

Answer 3

45% non locking constructs had implant failure - probability of implant failure significantly higher (more than 20x higher) with non locking

Question 4

Hammer, vet surg 2020
Predictors of comorbidities and mortality in cats with pelvic fractures

-what factors were associated with mortality?

Answer 4

increased number of injuries, increased fracture severity and neurological injury

Question 5

Bourbos, VCOT 2021
The Use of Intraoperative Skeletal Traction for the Repair of Pelvic Fractures: An Experimental Cadaveric Study

-how much traction was achievable with this system?

Answer 5

at least 2cm

Question 6

Roberts, VCOT 2021
Management and Long-Term Outcome of Acetabular Fractures in Dogs: A Retrospective Study of 49 Dogs

-most common location of fractures?
-what factor associated with worse CBPI scores?
-what % had new neurological deficits after surgical repair?

Answer 6

mid-third of acetabulum
conservative management
21% new neurological complications after surgical repair

Question 7

Cinti, VCOT 2020
Triple Pelvic Osteotomy Fixed with Lag Screw for the Treatment of Pelvic Canal Stenosis in Five Cats

-what mean canal enlargement was obtained?

Answer 7

20% mean canal enlargement

Question 8

Rollins, VCOT 2019
Evaluation of fluoroscopic-guided closed reduction versus open reduction of sacroiliac fracture-luxations stabilized with a lag screw

-what resulted in a lower rate of screw loosening

Answer 8

fluoroscopic guided screws had lower rate of loosening

Question 9

Han, JFMS 2022
Evaluation of a screw insertion landmark for a minimally invasive repair technique in induced bilateral sacroiliac luxation in feline cadavers

-describe the landmarks

Answer 9

1) line from cranial acetabulum to caudal iliac crest
2) line perpendicular to this line from caudal iliac crest.
drill hole goes half way along the second line

Question 10

Couper, JFMS 2020
Evaluation of prognostic factors for return of urinary and defecatory function in cats with sacrocaudal luxation

-what percentage of cats regained voluntary urinary funcction?
-what factor associated with decreased likelihood of recovery?

Answer 10

90% regained voluntary urinary function

higher neurological grade associated with decreased likelihood and longer duration to recovery

Question 12

Vardanega, JSAP 2024
Sacral fracture stabilisation using dorsal transiliac locking plates: 12 cases (2017-2023)

-what was the most common type of sacral fracture?
-What percentage had good to excellent outcome?

Answer 12

-Anderson type II
-100% good to excellent outcome

Question 13

Kang, VCOT 2024
Biomechanical Comparison of Double 2.3-mm Headless Cannulated Self-Compression Screws and Single 3.5-mm Cortical Screw in Lag Fashion in a Canine Sacroiliac Luxation Model: A Small Dog Cadaveric Study

-what depth of sacrum did the two screw constructs cover?
-what construct was strongest in what test?

Answer 13

40% depth
2x2.3mm headless compression screws stronger versus rotational forces
