ABSTRACT:
Prosthetic shock absorber rotation apparatus for a prosthetic leg includes an outer cylindrical element which may be secured to a prosthetic foot and a tubular member which extends in the opposite direction and which may be secured appropriately at an attachment location above or below the knee. A sleeve is disposed in the two members and a bushing is secured to the tubular member and moves with the sleeve. Extending between the sleeve and the outer cylindrical element are elastomeric elements. The elastomeric elements are disposed within the sleeve and bear against a wall in the outer cylindrical element to absorb shocks. A spring element attached between the outer cylindrical element and the tubular member allows limited rotational flexibility.
