Pelvic Fractures Flashcards
Bruce, VCOT, 2014:
Ilial fractures - DCP vs LCP
Biomechanical differences?
Bruce, VCOT, 2014:
No differences in mode of failure, displacement at failure or ultimate load at failure
Krebs, Vet Surg, 2014:
Feline ilial fractures - bone plate +/- IM pin
Biomechanical advantage of the addition of an IM pin?
Krebs, Vet Surg, 2014:
No biomechanical advantage of adding an IM pin to ilial fractures stabilized with bone plates
Stieger-Vanegas, VCOT, 2015:
- What fractures are more accurately diagnosed with CT compared to radiography?
- What fractures are diagnosed with similar accuracy with either CT or radiography?
- How can radiography be improved for diagnosis of pelvic fractures when CT is not available?
Stieger-Vanegas, VCOT, 2015:
- Sacral fractures (especially sacral body fractures), ischiadic table fractures and pubic fractures were more accurately diagnosed with CT than radiography
- Fractures of the acetabulum and iliac body, and coxofemoral and sacroiliac joint luxation or subluxation were diagnosed with similar accuracy using CT and radiography
- Right and left lateral oblique radiographs may aid in accurately diagnosing pelvic fractures when CT is not available
Schmierer, Vet Surg, 2015:
Lateral plating of feline ilial fractures
Screw loosening rates for DCP vs single locking plate vs double locking plate?
Schmierer, Vet Surg, 2015:
50% screw loosening rate for DCP, 8% screw loosening rate for single locking plate fixation, and 0% screw loosening rate for double locking plate fixation
Hoffberg, JVECC, 2016:
- Distribution of pelvic fractures?
- What % had concurrent intra-abdominal injury?
- What fractures are more likely to be associated with concurrent intra-abdominal injury?
- Overall survival to discharge?
Hoffberg, JVECC, 2016:
- 90% pubic fractures, 81% ischial fractures, 58% SI luxation, 43% ilial fractures, 30% acetabular fractures, 13% sacral fractures
- 37% had concurrent intra-abdominal injury
- Sacral fractures are more likely to be associated with concurrent intra-abdominal injury
- Overall survival to discharge: 89%
Singh, VCOT, 2016:
SI luxation repair
- Which approach was associated with better post-op reduction?
- Screw loosening rate for dorsolateral vs ventrolateral approaches?
- What % of screws were properly placed within the sacral body?
Singh, VCOT, 2016:
- Dorsolateral approach had better post-op reduction
- Screw loosening rate: 5% for dorsolateral approach vs 8% for ventrolateral approach
- 70-80% of screws were properly placed within the sacral body
Dejardin, VCOT, 2016:
SI lag screw fixation
- Which technique provided more accurate and consistent sacral screw placement - minimally invasive osteosynthesis or ORIF?
- What was the trend for the screws in the ORIF group?
Dejardin, VCOT, 2016:
- Minimally invasive osteosynthesis fixation provided more accurate and consistent sacral screw placement than ORIF
- There was a trend toward a cranioventral orientation of screws in the ORIF group
Silveira, VCOT, 2017:
SI luxation repair in cats
- Benefit(s) of intra-op radiology?
- What % of screws in the group without intra-op radiology exited the sacrum?
- What % of screws in the group with intra-op radiology exited the sacrum?
- What was the % of sacral width purchased by the screw in the group without intra-op radiology vs the group with intra-op radiology?
Silveira, VCOT, 2017:
- Intra-op radiology improved the position and sacral purchase of lag screws
- 47% of the screws in the group without intra-op radiology exited the sacrum
- 13% of the screws in the group with intra-op radiology exited the sacrum
- Screws in the group without intra-op radiology achieved 55% sacral width purchase, whereas screws in the group with intra-op radiology achieved 71% sacral width purchase
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?
Dejardin, Vet Surg, 2018:
0.9-3.8 degrees deviation from ideal trajectory
Pratesi, VCOT, 2018:
Bilateral SI luxation
How was SI reduction and stabilization achieved?
Pratesi, VCOT, 2018:
Use of a single 2.7mm cortical self-tapping transsacral screw and nylon nut
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?
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
