[1] The program was established at the University of Pennsylvania School of Veterinary Medicine by Gail Smith[2] in 1993, with the primary objective of reducing the prevalence of hip dysplasia in dogs.
[4] The PennHIP method was developed by Gail Smith at the University of Pennsylvania in 1983 with the current radiographic submission system dating back to 1993.
The device acts as a fulcrum at the level of the proximal femur to lateralize the femoral heads when the performing veterinarian exerts minimal adduction force.
[4] The first two previously mentioned radiographs are used to obtain precise measurements on laxity and joint congruence, while the extended view is needed to collect further information on osteoarthritis if present.
The purpose of these RXs is to obtain a technological calculated value that in the end an index of the joint laxity is given with less vulnerability to errors in comparison to the qualitative methods.
