Changing The Concept Of Canine Hip Dysplasia

by Dr. Wendell O. Belfield

It may interest breeders and fanciers of the larger breeds of dogs,that the winds of time are changing the concept of canine hip dysplasia (CHD). In the May, 1997 issue of the Journal of the American Veterinary Medical Association, were two papers discussing a new outlook on CHD.

The first paper, “Onset of epiphyseal mineralization and growth plate closure in radiographically normal and dysplastic Labrador Retrievers,” was a collaboration of seven researchers/educators at the veterinary schoool at Cornell University. The results of this study is as follows. “There were 26 radiographically normal left and right hip joints. Onset of mineralization of the proximal femoral epipysis and of the right proximal tibial epiphysis was significantly later in dysplastic than in radiographically normal puppies. The left femoral capital growth plates closed significantly later in dysplastic than radiographically normal joints, but other differences in growth plate closure were not detected.”“Clinical Implications — Endochondral ossification may be abnormal in dogs with CHD. The disease appears to affect multiple joints, even though it is most evident clinically in the hip joint.”

The second paper was presented by Jens Sejer Madsen, Ph.D., D.V.M. from the Small Animal Hospital, Department of Clinical Studies, Royal Veterinary and Agricultural University, Frederiksberg C, Denmark.
