Abstract: There is provided an acetabular cup liner for a total hip replacement (THR) prosthesis comprising an inner surface with a hemispherical portion having a radius of curvature. The hemispherical portion is disposed about a centerline and it intersects a hemisphere plane perpendicular to the centerline so that the intersection of the hemispherical portion and the plane define a circle having a radius equal to the radius of curvature. The liner further comprises a capture portion continuous with the hemispherical portion that has the same radius of curvature as the hemispherical portion and connects with the hemispherical portion at the hemispherical plane along a first arc of the circle on the plane, and extends a first distance out of the plane. The liner further comprises an insertion portion continuous with the hemispherical portion. The insertion region is connected with the hemispherical portion along a second arc of the circle on the plane.

Abstract: A computer implemented method and system is provided for managing one or more self-insured plans, where healthcare provider's discount rate may be dynamically or retroactively adjusted during each plan period based at least in part on, for example, the rate of utilization of in-network or in-system providers by a plurality of respective plan participants. In exchange for the discounts on its services, shared savings may be calculated and paid to the provider after the end of each plan period based at least in part on lower than expected claims.
