Abstract
Objective The aim of this study was to investigate the prevalence, breed predisposition and
fracture conformation of humeral condylar fractures (HCF) over a 10-year period. Results
were compared with published studies emanating from the United Kingdom exploring effect
of breed on HCF.
Methods Data for all canine admissions to the Veterinary Teaching Hospital at Kansas State
University were extracted for the period January 2010 to October 2020. Humeral fractures
were recorded and further subclassified as medial, lateral and ‘T’/‘Y’ condylar fractures.
The associations between HCF and subtypes with breed were assessed using univariate
logistic regression with a comparison group. Multivariable logistic regression was
used to evaluate the effect of breed while accounting for dog age, sex and neuter
status.
Results Of the 44,952 canine patients seen during the study period, period prevalence (95%
confidence interval [CI] for HCF was 0.26% [0.22, 0.31]). After adjustment for age
and neuter status, French Bulldogs were 49 times more likely to be diagnosed with
a HCF compared with the comparison breed group (odds ratio [OR], 49.0; 95% CI, 26.9–89.3).
After adjustment for age and neuter status, Cocker Spaniels (OR, 42.8; 95% CI, 16.8–108.6),
Boston Terriers (OR, 22.9; 95% CI, 11.0–47.9) and Brittany Spaniels (OR, 21.5; 95%
CI, 7.3–63.1) had the next highest increase in HCF compared with the comparison group.
Conclusion Based on a study population from the United States, French Bulldogs were 49 times
more likely to be diagnosed with a HCF compared with the comparison breed group.
