Veteran and nine-year-old girl find independence with new adjustable socket technology developed by Hanger Clinic

Las Vegas, Nev., Feb. 7, 2017 – Last week, 63-year-old Ken Muller and nine-year-old Lilly Biagini became two of the first amputees in the world to be fit with the new ComfortFlex® Adapt, an adjustable socket technology that empowers patients to control their own prosthetic socket fit with the turn of a dial. Hanger Clinic Vice President of Prosthetics Kevin Carroll, MS, CP, FAAOP (D), one of the developers of the technology, worked with both patients at a Hanger Clinic location in Las Vegas, Nevada.

Lilly, who previous needed her mother's help to remove or put on her prosthetic legs, says this about the ComfortFlex Adapt: "I do not have to ask my mom to help me. I feel powerful." Watch Lilly and Ken tell their stories to KTNV-TV (ABC):

About the ComfortFlex® Adapt socket system: The socket is where the prosthesis and the body connect, making it the most important part of any prosthesis. The ComfortFlex® Adapt socket system provides a new level of comfort and control for users. The system is anatomically contoured to provide a secure, comfortable fit for people who wear artificial limbs, while accommodating sensitive areas within their residual limbs. Designed with a low profile and maximize flexibility, each socket is custom made with Hanger Clinic's patented custom socket technology, guaranteeing an individualized, accurate fit that provides stability, control, and performance. More information on the ComfortFlex® Adapt technology is available here:

About Lilly Biagini: Nine-year-old Northern California resident Lilly Biagini had both her legs amputated above-the-knee in 2014, and has been walking independently for almost three years. With her original prosthetic sockets, Lilly had to remove her prosthetic legs to change the amount of "socks" covering her residual limb to ensure a comfortable fit with her prostheses. With the ComfortFlex® Adapt, Lilly will be able to adjust the fit of her prosthetic legs by herself for the first time, providing Lilly with the independence she needs to continue on as an energetic nine-year-old.

About Ken Muller: Las Vegas resident Ken Muller, a 63-year-old U.S. Air Force Veteran, had his leg amputated above-the-knee in 2010 as a result of injuries sustained during a motorcycle accident in 1974. Ken still rides motorcycles today and enjoys hunting, fishing and walking his two dogs. With the new ComfortFlex® Adapt, Ken is eager to be able to work in his yard longer without his prosthetic leg becoming uncomfortable, and aspires to play golf again.
