Fast facts about Canine Hip Dysplasia
    *Canine hip dysplasia (CHD) is the most commonly inherited orthopedic disease in dogs.
    *CHD is a degenerative, developmental condition, leading to painful hip osteoarthritis, stiffness, and diminished quality of life.
    *All dog breeds are affected by the disease, in some breeds more than 50% of dogs are afflicted.
    *The disease is polygenic and multifactorial.
    *The development of CHD is affected by environmental factors such as weight and age.
    *There is no medical or surgical cure for CHD.
    *CHD is a major concern for working dogs, pet owners, breeders and veterinarians.

What is PennHIP?

PennHIP is a not-for-profit veterinary health service at the University of Pennsylvania.

PennHIP is a multifaceted radiographic screening method for hip evaluation. The technique assesses the quality of the canine hip and quantitatively measures canine hip joint laxity. The PennHIP method of evaluation is more accurate than the current standard in its ability to predict the onset of osteoarthritis (OA). Osteoarthritis, also known as degenerative joint disease (DJD), is the hallmark of hip dysplasia (HD).

PennHIP is more than just a radiographic technique. It is also a network of veterinarians trained to perform the PennHIP methodology properly and, perhaps most importantly, it is a large scientific database that houses the PennHIP data. Radiographs are made by certified PennHIP members worldwide and are sent to the PennHIP Analysis Center for evaluation. The resulting data is stored in the database, which is continually monitored as it expands. As more information becomes available, the PennHIP laboratory is able to obtain more precise answers to questions about the etiology, prediction and genetic basis of hip dysplasia.

PennHIP publishes its findings in scientific journals. Published information is disseminated to all PennHIP members; it is also shared with interested breed clubs and routinely appears in publications within the dog fancy.

PennHIP is composed of three major components:

    A diagnostic radiographic technique
    A network of trained veterinarians
    A medical database for scientific analysis
