Abstract: 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.

Abstract: Prosthetic hip stems for use in prosthetic hip joints and, in particular, provides prosthetic hip stems that are designed to achieve more optimized outcomes with certain types of patient anatomy, such as the anatomy of female patients and/or patients having osteoporosis. Each hip stem in a family or set of hip stems has diaphyseal width, metaphyseal width, offset, and head height dimensions. In a set of hip stems of increasing nominal size, the diaphyseal width dimension increases substantially non-proportionally to the corresponding increase of the metaphyseal width, offset, and head height dimensions, thereby providing a family or set of hip stems that is particularly adapted for patients having osteoporosis, in which the cortical bone of the diaphysis of the femur becomes thinner with progression of the osteoporosis.
