Abstract: An improved flexion biased prosthetic hip includes an extended biasing spring to permit hyperextension of the joint relative the frontal plane of the user. In addition, a bifurcated actuator rod is disclosed. This actuator rod transmits the biasing force of the extended biasing spring from a collar surrounding the leg pylon to the hip mounting plate. The bifurcated actuator rod eliminates the binding associated with the previously used actuator members that were formed as a plate with a roller contacting the pylon.
Abstract: A two-element prosthesis is provided with a resilient connector that permits limited rotation of one element relative the other about the three axes of the two elements as defined by the junction of the two elements. The resilient connector further absorbs a limited amount of compressive shock transmitted from one element to the second element. The resilient member includes a sensing system that indicates a compressive force at the resilient member in excess of a predetermined amount.
