R/U fractures

Question 1

Schmokel JSAP 2021

Prospective study
25 dogs, 7 cats, average 4kg
Simple closed RU #

Answer 1

All union
3% deep ssi

Question 2

Higuchi JSAP 2021

Retrospective
RU diaphyseal # in toy dogs, average 3.5kg

Orthogonal plate, nonlocking cuttable

Cranial plate removed 40d postop

Answer 2

5% major complications (re # after plate removal)

Question 3

Muroi VCOT 2021

Retrospective 236 # in toy breed dogs
Implant-induced osteoporosis on rads - index of pixel values cf humeral condyle

Answer 3

Sig decrease in pixel 1-12m postop

Implant-induced osteoporosis persisted in dogs >6mo for 1-12m
improved after 3m in <6mo

Question 4

Aikawa VS 2019

140 distal RU # in toy/mini dogs
Free-form type II ESF

Answer 4

All healed
3% major complications

Question 5

Aikawa VCOT 2018

ORIF 65 distal RU # in smal dogs

Answer 5

all healed
6% major copmlications

Question 6

Makar JFMS 2024

Retrospective 49 cats
RU diaphyseal #
single vs double fixation
36% of single fixation had intact radius or ulna

Answer 6

No diff bwt double (8%) vs single (11%) major comp

single plate 14x more likely to have successful outcome

Question 7

Angorro

Toy poodles R/U #

Answer 7

FEA - concentrated stresses in the distal regions of the toy poodle’s radius bones

Removal of 1.5 vs 2.0 LCP notched T plate
Plates with longer lengths showed a more uniform stress distribution on the one-third distal radius

Localized stress concentration is observed around the screw holes, while trabecular bone regions near the screw holes exhibit lower stress levels
