Cassidy adjusting well to “bionic” leg
Cassidy, the three-legged dog we first told you about last month, seems to be getting around well on his new prosthetic leg, if the footage in this CBS report is any indication.
Cassidy was missing one of his hind legs when he was adopted from a New York City shelter in 2005 by Steven and Susan Posovsky.
Veterinary Orthopedic Surgeon Dr. Denis Marcellin-Little at the North Carolina State University College of Veterinary Medicine outfitted Cassidy, a German shepherd mix, with his new titanium leg in July — after much trial and error.
“We worked for about a year first to try to design an external brace that was fairly sophisticated, but did not work very well,” Marcellin-Little told CBS .
“There were two removable legs were made for him. Slip-on legs, which he was able to just kick off,” Steven Posovsky said. “At that point, they took out some computer diagrams and said let’s look into this possibility of an osteo-integrated leg.”
Cassidy’s artificial leg is a permanent prosthetic. A titanium rod was implanted into Cassidy’s lower leg bone. Over several months, they fused together. A custom designed carbon fiber foot with a rubber tread for traction screws right on to the implant.
“Now he walks for two, three hours and not a hint of fatigue,” Steven Posovsky said. “Watching him run on the beach is a very emotional thing for me personally. But a lot of tears of joy.”
