Abstract:
An impact and torque absorbing prosthetic shock module, comprising:an outer pylon having a proximal end and a distal end, said outer pylon having at least one internally threaded surface; an inner pylon having a proximal end and a distal end telescopingly engaged with said outer pylon so that an annular interface is formed between said pylons, said inner pylon adapted to move axially and rotationally with respect to said outer pylon; a resilient element within said inner pylon having a proximal end and a distal end and being sized and configured to resist relative axial displacement of said pylons; a torque-resisting cuff connecting the pylons and providing torsional resistance to relative rotational motion between said pylons; and an internal support for said distal end of said resilient element, said internal support being threadingly engaged within said outer pylon.
