  1. Combat Wound Induced Prosthetics Ryan Dolan

  2. Casualties in Iraq and Afghanistan • Over 50,000 soldiers wounded • 16,000 of these have been severe, disabling wounds • Including over 1500 soldiers who underwent an amputation Main Cause: Improvised Explosive Devices (IEDs)

  3. 4 Main Types of Prosthetics • Transradial:Amputation below the elbow • Transhumeral: Amputation above the elbow • Transtibial: Amputation below the knee • Transfemoral: Amputation above the knee

  4. Components of Artificial Limbs The Pylon: The internal frame or skeleton of the limb The Socket: Interface with the stump or residual limb Suspension System: Keeps the limb attached to the body • Myoelectric Prosthetics: • Use sensors attached to the prosthetic to interpret muscle, nerve, and EMG activity • Translates these signals into information that the motors and circuits of the prosthetic can understand • Mainly found in upper extremity prosthetics

  5. Glucose Powered Fuel Cells • Generates electricity from the glucose present in cerebrospinal fluid • Cerebrospinal fluid can be found in both the spine and the brain • Can power implants that interpret brain activity, and as a result can be used to send signals to prosthetic limbs

  6. Jan Scheuermann • Paralyzed from the neck down • MIT created a prosthetic limb that is controlled by Jan’s thoughts • First working example of mind-controlled prosthetics • The arm is called Hector, and it has the potential to change the world of prosthetics as we know it

  7. Major Robert Eldridge2nd Batt, 7th SFG • Lead vehicle struck by anti-tank mine, which caused his left leg to be amputated upon arrival at the hospital • Spent 6 months at Walter Reed hospital recovering from his injuries • Along with help from other special forces soldiers, and his prosthetic leg, MAJ Eldridge returned to active duty and was conducting combat operations only 3 years after his injury
