Rescued Dog Gets Prosthetic Limb


Cassidy was found wandering the streets of the Bronx, with his right rear leg cut off. He was 30 pounds underweight, and most of his fur was gone.
Cassidy was scheduled for euthanasia. But a morning news program ran a story on him, and Steve Posovsky was watching.
A retired dentist who lives in Florida and Long Island with his wife Susan, Posovsky says he “had to get” Cassidy when he saw the report.
That was in August of 2005. Fast-forward three years. Cassidy had his health back, but still couldn’t walk long distances without getting tired. He’d go “about 10 minutes and plop down and need a rest,” says Posovsky.
Steve and Susan contacted a veterinary surgeon in North Carolina and had a prosthesis made for Cassidy, but it kept coming off. So they decided to have a permanent one done.

The process is called “osseointegration.” An implant is inserted directly into the bone, where it fuses with the bone. A c-shaped removable foot attaches to it. The technique is so cutting-edge it may someday benefit humans.
Now, Posovsky says, Cassidy can walk “for hours” without getting tired.
