US Patent:

20110166668, Jul 7, 2011

Filed:

Mar 17, 2011

Appl. No.:

13/050365

Inventors:

Dean M.J. Acker - Warsaw IN, US
Stephen H. Hoag - Warsaw IN, US
Danielle L. Whitlock - Warsaw IN, US
Wayne G. Paprosky - Winfield IL, US

Assignee:

ZIMMER, INC. - Warsaw IN

International Classification:

A61F 2/36

US Classification:

623 2315

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.
