The major desideratum of the screening action of the hip dysplasia is the early discovery of the disease and its highlighting at an early stage. Hip dysplasia is interpreted as an abnormal and / or defective development of the hip (hip joint), which can cause excessive wear of the articular cartilage due to the support of body weight leading to the development of arthritis, often called degenerative joint disease or simply osteoarthritis, these terms being used randomly. All these morphofunctional changes can be detected early, by different methods of observation, which necessarily involve X-ray radiological examination, performing a complex analysis of the images studied, according to the recommendations of various international organizations such as FCI Fédération Cynologique Internationale (FCI) - score which includes measuring the Norberg angle, the Orthopedic Foundation for Animals (OFA), the PennHIP Program - which involves measuring hip laxity, etc.
