The dog presented to the Neurology and Neurosurgery Service at Pride after the dog's GP vet had diagnosed a tumour.
The neurological examination was consistent with a thoracolumbar lesion and the X-rays showed a radiopaque mass with bony lysis on the third lumbar vertebral body.
Annette Wessmann, an EBVS European Specialist in Veterinary Neurology at Pride said: “We chose to do a CT scan based on examination and the X-rays.
“It confirmed the suspicion of a neoplastic lesion and ruled out other tumoral focus along the rest of the spine and other organs."
A customised titanium implant was designed for the dog's spine in collaboration with BETA Implants.
Rosario Vallefuoco, an RCVS and EBVS Small Animal Surgery Specialist and Head of Small Animal Surgery at Pride said: “It was a case of combining our experience with that of the engineers.
“The original implants had been designed for humans, and we had to imagine what would be required for a dog and work out at every step what changes we would have to make.”
The surgery took place in three different stages, the first being L3 vertebra skeletonization and dorsal lamina removal.
The second step was vertebral body removal.
Finally, the third step was vertebral reconstruction using the designed implants.
The whole procedure took six hours, and the dog was up and walking again within 12 hours.
Subsequent histopathology assessment of the mass confirmed osteosarcoma, so the surgery is being followed up with chemotherapy.
Following the success of the surgery, Pride Veterinary Referrals says it now hopes to help other dogs with similar conditions.
