Welcome to PennHIP
PennHIP is a not-for-profit program wholly owned and operated by the University of Pennsylvania. Our mission is to develop and apply evidence-based technology to direct appropriate breeding strategies aimed at reducing in frequency and severity the osteoarthritis of canine hip dysplasia.
PennHIP incorporates a new method for evaluating the integrity of the canine hip. It is accurate in puppies as young as 16 weeks of age. It has great potential to lower the frequency of CHD when used as a selection criterion.
New Breed Laxity Update!
The breed laxity statistics have been generated for February 2013. The statistics are available to all certified PennHIP veterinarians . Remember to login to gain access.

We have some recent publications that will likely be of interest.
Officially released in December is the new Veterinary Surgery: Small Animal two volume set (Tobias and Johnston eds) in which we have a comprehensive chapter on Pathogenesis, Diagnosis and Control of Canine Hip Dysplasia. The chapter covers research up to the present day and it is a "must read" for all PennHIP members and those having a genuine interest in canine hip dysplasia.
We also have two new manuscripts in the January 2012 issue of Veterinary Surgery. Here, for the first time we report on radiographic evidence demonstrating the chronology of CHD development in a cohort of dogs followed for life. In the second manuscript in the issue we investigate the unique hip joint phenotype of a chondrodystrophic breed, the Pembroke Welsh Corgi. Thanks to all PennHIP members for contributing case material for this latter publication.

PennHIP vs OFA
A new scientific paper has just been published in the Journal of the American Veterinary Medical Association entitled "Evaluation of the relationship between Orthopedic Foundation for Animals' hip joint scores and PennHIP distraction index values in dogs" (pg 532-541). This study shows that dogs judged as "normal" by the OFA can have clinically important passive hip joint laxity as determined by the PennHIP method. The results suggest that OFA scoring can underestimate susceptibility to osteoarthritis in dogs, which may impede progress in reducing or eliminating hip dysplasia through breeding.

Dr. Smith was interviewed by Lisa Stahr, host of Special Pets, Special Needs. Gail talks about the PennHIP method and how it can predict the likelihood of getting Degenerative Joint Disease/Osteoarthritis later in life.
