Femoral stem-type prosthesis

摘要

An improved stem-type prosthesis, including a head, stem and neck providing reduced bending and shear loading of the neck thereby allowing the use of a smaller neck to improve the range of motion between the prosthesis and an acetabular cavity and to allow the use of a more complete spherical head thereby improving wear and separation resistance of the prosthesis from other components such as from an acetabular component.
