The University of Pennsylvania Hip Improvement Program (PennHIP) is a multifaceted radiographic technology (x-ray) 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. Osteoarthritis, also known as degenerative joint disease (DJD), is the hallmark of canine hip dysplasia (CHD).

The PennHIP method is a different way to assess, measure and interpret hip joint laxity. It consists of three separate radiographs: the distraction view, the compression view and the hip-extended view. The distraction view and compression view are used to obtain accurate and precise measurements of joint laxity and congruity. The hip-extended view is used to obtain supplementary information regarding the existence of DJD in the hip joint.

On average the distraction view has been shown to reveal 2.5 - 11 times more hip laxity (depending on breed) than the hip-extended view. Also the PennHIP method can measure the laxity of a hip joint with greater precision than the hip-extended method. The degree of hip joint laxity, as measured by the PennHIP method, has been shown to be the most important risk factor in determining whether a dog is prone to developing CHD.

This group is opened to Bernese Mountain Dog breeders who would be interested in sharing their experience with PennHIP. We would like to join together on this list to discuss our breeding stock, help other breeders who want to breed with quality "PennHIP" berners and discuss ways of promoting PennHIP certifications as one of the best methods to improve hip status in our breed.
