Prosthetic ellipsoidal acetabular cup

摘要: An acetabular cup prosthetic device comprised of an outer shell component and a inner bearing insert the method implanting within patient. The surface for present invention has plurality regions which conform to curvature at least one ellipsoid. To implant component, acetabulum patient is spherically reamed size slightly smaller than that component. As inserted into shaped acetabulum, interior cavity deforms assume substantially ellipsoidal curvature, producing interference fit between rim region upper peripheral acetabulum. remaining shape or shapes defined by so contact established without development ejection forces therebetween.
