Abstract
Multi-axial prosthesis assemblies that include a resilient closed undulating member are used to provide vertical and rotational movement for lower limb prostheses. A shaft is located through a resilient bumper, with a first prosthetic member is fixedly attached to the shaft and engages a first surface of the undulating member, and a second prosthetic member comprises a lumen to movably receive the shaft. The prosthetic members are engaged to the resilient bumper with projections that are located in the recesses of the resilient bumper and the prosthetic members and the bumper are configured so that the projections from each member are offset from the projections of the other member, which results in an undulating appearance to the outer surface of the resilient bumper.
