Objective To critically review the different screening systems used for canine hip dysplasia ( CHD ) and their impact on the prevalence of the disease. Study design Critical literature review. Methods Literature search through P ub M ed ( N ovember 1959– O ctober 2011) and the O rthopedic F oundation for A nimals ( OFA ), F édération C ynologique I nternationale ( FCI ), B ritish V eterinary A ssociation/ K ennel C lub ( BVA / KC ), and P ennsylvania H ip I mprovement P rogram ( P enn HIP ) websites. Results 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 P enn HIP and D orsolateral S ubluxation ( DLS ) systems, both distraction methods, have not reported on prevalence but seem to be important heritable traits in genomic screening of dysplastic dogs. Conclusion 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.
