Griffin JAVMA 2023
modified hemipelvectomy 20 dogs 3 cats for tumour excision
(partial sacrectomy/vertebrectomy, osseous excision crossing midline + amp, reconstruction with muscle/mesh)

A

Q

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

A

single locking superior to single nonlocking

double plating increased stiffness and resistance to failure and is a strong nonlocking alternative

Q

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

A

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

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)
