To critically review the different screening systems used for canine hip dysplasia (CHD) and their impact on the prevalence of the disease.
Critical literature review.
Literature search through PubMed (November 1959–October 2011) and the Orthopedic Foundation for Animals (OFA), Fédération Cynologique Internationale (FCI), British Veterinary Association/Kennel Club (BVA/KC), and Pennsylvania Hip Improvement Program (PennHIP) websites.
The OFA, FCI, and BVA/KC screening methods, which use the hip-extended radiographic projection, have had relatively minor success on CHD prevalence. These screening approaches are prone to conflicting data regarding interobserver agreement. The PennHIP and Dorsolateral Subluxation (DLS) systems, both distraction methods, have not reported on prevalence but seem to be important heritable traits in genomic screening of dysplastic dogs.
A shift towards genome screening yields a promising future combating CHD, although further investigation towards fine-mapping in the search for genes, responsible for CHD, is necessary.
