Cat amputee fitted with 'bionic' feet
(CNN) -- If cats have nine lives, they may have just acquired a 10th -- thanks to a groundbreaking surgery that saved the life of a feline double amputee.
A British cat, Oscar, has made a full recovery after being fitted with a pair of prosthetic feet in November. The cat's hind paws were severed by a combine harvester.
The three-hour procedure, performed at an animal hospital in Surrey, England, by neuro-orthopaedic veterinary surgeon Dr. Noel Fitzpatrick, could serve as a model for human amputees.
Oscar's custom-made implants, ITAPs (Intraosseous transcutaneous amputation prosthetics), were modeled after deer antlers, which have a honeycomb structure that bones can grow through and skin can grow over.
By using computer-generated technology, a team of veterinarians and scientists designed a feline foot that mimics the way a cat walks and runs.
Oscar's implants were attached to his bones and then covered by hydroxypatite, which allows bone cells to grow onto the metal. Skin can then grow over the ITAP to form a seal against bacteria and keep infections at bay.
Custom-built paws were attached to the end of Oscar's prostheses, allowing him to run and jump like normal cats. One video of Oscar walking on his artificial feet has attracted more than 346,000 views on YouTube.
Here's the video they mention.
