1. An actuated prosthesis for replacement of an amputated limb, the prosthesis comprising:

  • a primary joint member;

    a socket connector assembly for connecting a socket to said primary joint member;

    an elongated structural member having opposite ends spaced apart along, a main longitudinal axis;

    a connector assembly for connecting a terminal portion to on end of said structural member;

    a pivot assembly for operatively connecting the structural member to the primary joint member to permit relative rotation between said primary joint member and said structural member about an first axis defined by said pivot assembly;

    a linear actuator connected at one end to said structural member and at the opposite end to said primary joint member at a location spaced from said pivot assembly, whereby extension or retraction of said actuator induces a corresponding rotation of said primary joint member relative to said structural member about said pivotal axis.
