University to launch hip replacement registry


A national registry for dogs undergoing hip replacements is to be launched by the University of Liverpool and the British Veterinary Orthopaedic Association (BVOA).

Hip replacement has been performed in dogs since the 1970s and has become an increasingly common procedure. However, because artificial hips are intended to last for the rest of the dog’s life, there is a need to track the performance of the artificial joint and to understand why some hips might fail.

The Registry will be hosted by the University of Liverpool and it is hoped that thousands of dogs will be recruited to create a powerful database.

Just as in human medicine, there are various designs of hip that can be implanted but there is little information on the relative merits of each type. Hip registries in humans have been instrumental in providing good long-term outcome information on the advantages and disadvantages of various implant designs. In addition, the canine registry will collect and analyse data on the performance of hip replacement in different breeds, bodyweights and ages of dog.

Professor John Innes, who will lead the Liverpool team, said, “We are delighted to collaborate with BVOA on this project. We will use secure, on-line data submission procedures to maximize our dataset. We hope to collect data on a large number of canine hip replacements from across the UK in a relatively short period of time and we will then follow their progress for at least 10 years. We hope to have a real impact in terms of improving the success rate of canine total hip replacement. This should bring real benefits to affected dogs and their owners.”

Dr Chris May, chairman of BVOA said, “The BVOA is uniquely placed to bring together veterinary surgeons in collaborative projects for the benefit of pet animals with orthopaedic problems in the UK. The initiative of the Registry for Canine Hip Replacement, championed by Professor Innes is the first of its type in the world and it will be of undoubted benefit to the many dogs that suffer painful conditions of the hip.

In addition, the Registry will pave the way for similar co-operative projects in the future, which is an important step because such collaborative ventures are essential to the continued sound scientific development of veterinary medicine. The BVOA is proud to be instrumental in this world leading project.”
