Pelvic fractures Flashcards
Kenzig BMC 2017
SOP vs DCP
simple iliac # model in dogs
no sig diff DCP vs SOP
Petrovsky VS 2021
Retrospective study 63 iliac # in dogs
locking vs nonlocking
30% implant failure - 45% nonlocking, 4% locking
use of nonlocking sig risk factor - 20x more likely to fail
Blakely BMC 2019
Ex vivo canine model
SOP vs screw/wire/PMMA vs acetabaular plate
SOP stiffer than acetabular plates
Piana VCOT 2020
LCP/VetLOX/SOP for 18 acetabular fractures in dogs
92% return to fx
comp rate similar to nonlocking implants
Roberts VCOT 2021
retrospective review 49 dogs acetabular fractures
majority mid > caudal > cranial
30% neuro deficits on presentation
long term 10% major comp with sx, 30% with conservative mx
Griffin JAVMA 2023
modified hemipelvectomy 20 dogs 3 cats for tumour excision
(partial sacrectomy/vertebrectomy, osseous excision crossing midline + amp, reconstruction with muscle/mesh)
36% partial sacrectomy/vertebrectomy postop mobility issues
18% major comp - acute L7#, recurrence of tumour
Schmiere VS 2019
Ex vivo study feline iliac comminuted gap #
dorsal plate + nonlocking screws
lateral plate + nonlocking screws OR locking screws
lateral and dorsal LCP + nonlocking screws
cyclic load to failure
single locking superior to single nonlocking
double plating increased stiffness and resistance to failure and is a strong nonlocking alternative
Paulick VS 2022
biomechanical study cat model
4 locking systems : ALPS 5, ALPS 6.5, 2.0 LCP, 1.9-2.5 Fixing)
vs 2.0 DCP
cyclic load to failure
all DCPs screw loosened
bone slicing occurred in all locking systems -> ilium highly susceptible due to thin cortices
ALPS 5 not recommended
locking systems recommended for iliac #s
Hammer VS 2020
retrospective 280 cats with pelvic #
20% mortality - higher with severity of pelvic #, concurrent body regions affected, neuro signs
Adrian VCOT 2024
SOPs with cortical screws 20 pelvic # in cats
5% major intra, 25% major postop (2x gr trochanter removal, 3 SOP removal)
full fx in all cats - low incidence of canal narrowing and screw loosening
Murugarren VCOT 2023
LCP for acetabular # in 15 cats
full fx half, acceptable half - overall 100%
LCP suitable acetabular # in cats
Haine
17 acetabular 3 in cats
screws//wires/pins+PMMA, DCP, locking
56% presenting neuro deficits
29% transient neuropraxia postop
33% of preop deficits persisted postop
18% major comp (implant failure resulting in FHNE, pin loosening from trochanteric osteotomy)
20% full fx, 80% acceptable - overall 100%
