PerFiTS patients

Fitzpatrick Referrals’ Bionic Heroes

Published 16.02.17

We’re proud to have helped many dogs and cats facing total limb amputation to go on to live happy and adventurous lives on four paws with PerFiTS prostheses.

PerFiTS patients

A PerFiTS (Percutaneous Fixation to Skeleton) prosthesis, innovated by Professor Noel Fitzpatrick, is a uniquely designed implant that is packed full of groundbreaking technology.

Special coatings allow the patient’s bone to incorporate into the metal of the implant meaning the implant becomes a physical part of the patient’s skeleton. Further specialist coatings at the interface where the implant passes through the skin allow the skin cells to incorporate into the metal ensuring a robust, bacteria proof, seal forms between the skin and the implant. The portion of the implant that passes through the skin allows an exoprosthesis, or foot, to be attached to the endoprosthesis.

There have been over 20 patients who have benefited from this pioneering surgery. As the only practice in the world offering this service, we feel very honoured to have given the gift of mobility to many dogs and cats across the country.


One of the latest patients to receive this life-changing surgery at Fitzpatrick Referrals is Rodney, a West Highland Terrier rescue puppy who has no back feet and only a thin layer of skin around his stumps. Rodney is the second dog in the world to receive two bionic back feet and his story was followed in series 8 of The Supervet, which returned to Channel 4 on Thursday 16th February 2017.

Here are a few of our other patients to have received the PerFiTS prosthesis, some of whom you may remember from past episodes of The Supervet on Channel 4.


Oscar was the first animal in the world to receive a double amputation prosthesis on his back legs after his rear paws were chopped off by a combine harvester in 2009.

Peanut was born with deformed front legs and with his love of outdoor life, his feet were constantly getting infected. Peanut’s life was transformed with the application of bone-anchored prosthetics by Professor Noel Fitzpatrick and he continues to live an adventurous life roaming the woods as the only cat in the world with two front bionic feet.
