    摘要: Prosthetic hip stems and acetabular cups for use in prosthetic hip joints. The hip stem may include a core having a stem portion and a neck portion, a polymer matrix layer substantially covering the stem portion of the core, and a porous metal layer substantially covering the polymer matrix layer. The polymer matrix layer connects the core and the porous metal layer and provides a stiffness for the hip stem which more closely mimics the stiffness of bone than do known hip stems. The hip stems and acetabular cups additionally include a number of improvements adapted for more optimized results with certain types of patient anatomy, such as the anatomy of female patients, for example.

    摘要: The invention solves the problem of anchoring a prosthetic component into compliant, cancellous bone by a thin, preferably pure titanium, or a titanium-based alloy, perforated, hence hydraulically open, shell (1, 13), spaced apart from the second, non-perforated shell (2, 14). In most applications, dictated by the anatomical site of insertion, shells are approximately hemispherical in form, connected to each other at the equator The solid shell may contain a further, articulating component of the joint, e.g. a polymer or a ceramic insert, or it may serve that function itself. One or both components of a joint prosthesis can be anchored according to the invention.
