Humeral Condyle

Question 1

Smith
Breed associated with humeral condylar fracture
JSAP 2020

Answer 1

Frenchies 41%
English Springer Spaniel 15%

Lateral 70%
Medial 9%
T/Y 21%

Median age at the time of fracture was 4 months

Question 2

Moores
Natural History of Humeral intracondylar fissure
JSAP 2017

Answer 2

Mean fissure size of 50%
~fractured at a mean of 14 months after diagnosis
~18% progressed to fractures
~24% required Sx

Question 3

Gonsalves
Screws for humeral condylar fx
VCOT 2016

Answer 3

3.5 mm Cortical Bone Screw
~36% stiffer than 3.0 mm Headless compression Screw

Although both screws provide similar anatomical reduction and yield strength to condylar fracture fixation in adult canine humeri.

Question 4

Villamil
Breed impact on Humeral condylar fx
VetSurg 2020

Answer 4

Breeds associated with HCF
~Frenchies (6.58X medial)
~Spaniels

Epicondylar plate
~fewer complications than lag screw & k-wire

Question 5

What travels through the humeral supracondylar foramen of the cat

Answer 5

Median n

Brachial a.

Question 6

Repair of physeal fx of the proximal humerus

Answer 6

~2 k-wires and Tension Band
~2 k-wires
~Lag screw

Question 7

Repair of physeal fx of the greater tubercle

Answer 7

2 pins and tension band

Question 8

Repair of physeal fx of greater tubercle and humeral head

Answer 8

~K-wire & tension band

~Lag screw & K-wire

Question 9

Repair of the humeral head

Answer 9

Lag screw & K-wire
