On Monday, Max Ortiz Catalan, a researcher at the Chalmers University of Technology in Sweden, has announced an innovative mind-controlled prosthetic arm that mimics a lifelike sense of touch. This is what the future of prosthetics looks like and where prosthetic limbs will go. Max has created osseointegrated prosthetic arm with direct structural and functional connection between an artificial titanium implant and living bone, nerves and muscles! An electrode neural control system is connected to nerves, that provides the amputee with sensations and feelings that simulate a real hand’s sense of touch.

Clara Gardner plans undergo osseointegration surgery

Clara Gardner

Clara Gardner has suffered severe injuries and permanent disabilities in a car crash. It took place in 2008, when she was just 16 years old. Clara was hit by a drunken driver who was going very fast at 50 mph. And she lost both her legs from the knee down in that tragic car accident. After the accident, Clara Gardner spent three years in a wheel chair. For the past four years, she had tried to walk using traditional prosthetic legs with a socket attachment system. But socket prostheses are heavy, painful and difficult to fit. So she decided to find a new kind of prosthetic legs that would allow her to walk again comfortably and without feeling pain. But when Clara Gardner heard about osseointegration she had hope of a future with much less struggle.

Percutaneous osseointegrated prostheses for amputees

Osseointegration is defined as the formation of a direct interface between an implant and bone, without intervening soft tissue. The term refers to the direct structural and functional connection between living bone and the surface of a load-bearing artificial implant. The surgical procedure first started in Sweden in 1990. But US doctors have began to practice percutaneous osseointegrated prostheses (POP implant) only in 2015. The first surgeries for the two veterans took place on Dec. 7 and Feb. 8, 2015, when was involved implanting the device into the femur bone and attaching a post to the femur component of the device through the skin. During this year, doctors at the Salt Lake VA plan to attach osseointegrated prosthetics for eight amputee veterans.
