ABSTRACT:
An impact reducing prosthetic pylon has a distal component which can be attached to a prosthetic foot and includes a housing within which the proximal component can slidably fit. A resilient bumper-like member formed of a foam is positioned within the housing and is compressed by the proximal component when the prosthesis is under a load. Relative rotation of the proximal and distal components is prevented, but a limited, resiliently damped rotation may be permitted.
