ABSTRACT:
A functional ankle for a prosthetic limb comprising an elastomeric member and a flexible member. The elastomeric member separates the prosthetic foot from the shin. The elastomeric member allows the foot to move relative to the shin while providing plantar/dorsi flexion, inversion/eversion and rotational motion singularly or in combination. The foot and shin are connected by the flexible member which allows relative motion while providing structural integrity.
