Pet Health By the Numbers: Prevalence of Bone Fractures in Dogs & Cats
In each issue of Today’s Veterinary Practice, Pet Health by the Numbers correlates article topics with statistics provided by Banfield Pet Hospital (banfield.com). These statistics are extracted from data collected from the medical records of nearly 2.4 million dogs and 480,000 cats presented to more than 890 Banfield Pet Hospitals in 2014.
Learn more about data collection by reading Welcome to Pet Health by the Numbers (January/February 2014 issue) and Key Findings from the State of Pet Health 2014 Report (May/June 2014 issue), both available at tvpjournal.com.
The following tables outline the prevalence of selected bone fractures in dogs and cats presented to Banfield Pet Hospitals in 2014. Fractures are discussed in A Practitioner’s Guide to Fracture Management, Part 1: Diagnosing Fractures & Choosing a Fixation Technique.
Path to Pet Wellness: No large retrospective study of fracture incidence in dogs in North America has been published since 1994,1 and no similar study has ever been done in cats. These data confirm previous reports that juvenile dogs and cats have a higher incidence of fractures.2
In contrast to dogs at university referral hospitals,1 the Banfield primary care data contains far fewer ilial category (also includes acetabular) fractures, suggesting that ilial and acetabular fractures may be underdiagnosed in general practice compared to appendicular fractures, or that (less likely) they are of low overall incidence but are more likely than appendicular fractures to be referred to specialists.
Radial fractures in dogs are higher here than previously reported at university referral hospitals,1 which suggests that an unexpectedly high number of toy dogs with radial fractures are treated by external coaptation (cast, splint) in local practices, and are, therefore, at risk for later nonunion.
Prevalence of fractures in cats (femur fractures > tibia > radius > humerus) shows a nearly 100% higher incidence of femur and 50% lower incidence of radial fractures compared with dogs. While etiology in these data is not reported, the distribution of fractures in cats presented here mirrors a previous report of cats with fractures from high-rise syndrome.3
Further, more detailed evaluation of the Banfield database would be of great benefit to veterinary science.
