There are 3 sets of x-rays taken during an official PennHip evaluation - one set is identical to the ones (at least for OFA, I don't know about other countries) used in a normal, standard evaluation that is "judged". So if someone does decide to make a PennHip evaluation, the vet only needs to make an extra set of that film at the same time to submit to the normal registry for their country. PennHip also has a vet (or might be more than one) look for deformities in that view - if you look at a report, it will say if dog has "DJD" = degenerative joint disease = typically HD.
There is a special tool used in PennHip x-rays that extends, or pulls the joint out - showing the laxity/looseness of the tendon.
Yes, all films must be submitted to the University of Pennsylvania - where they use results in research. It also makes the controls and results more accurate - since it is required that owners allow the dog's results to be used in statistics for the breed, in addition to the training required of all vets taking the x-ray, and the numerical measurement.
