THE CHALLENGE The loss of a limb to injury or disease is devastating, both emotionally and physically. In addition to adjusting to a new way of life, amputees are often challenged with identifying and acquiring an appropriate prosthetic device. They looked to the engineering team at Avient for material selection and manufacturing guidance.
