Hanger Clinic patients first in world to be commercially fit with Triton smart ankle

Las Vegas, Nev., February 11, 2015 – Last week, John Redfield and Vernita Jefferson became the first amputees in the world to be commercially fit with the Triton smart ankle, the world’s newest microprocessor-controlled prosthetic ankle-foot. The Triton’s innovative technology allows users to walk with confidence, without having to think about their next step. Hanger Clinic Vice President of Prosthetics Kevin Carroll, MS, CP, FAAOP, fit both patients at a Hanger Clinic location in Las Vegas, Nevada.

To hear Redfield and Jefferson's thoughts on how the Triton will improve their lives, watch the following segment from KVVU-TV (FOX):

About the Triton: Using embedded sensors and built-in Bluetooth connectivity, the Triton smart ankle can sync to a mobile app on users’ smart phones, allowing for real-time feedback and adjustments from both the user and prosthetist. Other attributes include:

- The ability to adjust 50 times per second in real time.
- A 34-degree range of motion, allowing the user to navigate a variety of terrains, including inclines and declines.
- An adjustable heel for up to a two-inch heel height, allowing users the freedom to wear the type of shoes they would like, including heels.

About the Redfield and Jefferson: Manchester, Conn. resident John Redfield, 52, lost his leg below the knee in April 1991 when he was hit by a van while riding his motorcycle. Just seven months after his accident, he participated in a road race nearly five miles long and has been running ever since with advanced prosthetic technology. Chicago, Ill. resident Vernita Jefferson, 73, is an avid swimmer who had a below-the-knee amputation in 2007 after she developed peripheral arterial disease. She continues to enjoy water aerobics classes, participates in church choir, and mentors other amputees.

During the development of the Triton smart ankle, the manufacturer of this mechatronic technology, Ottobock, partnered with Hanger Clinic for the clinical evaluation, application and testing. The technology is currently available exclusively to Hanger Clinic.
