  • Publication number: 20030074083
    Abstract: The invention relates to a femoral neck prosthesis having a spherically shaped head (1), by which a centre (2) of a sphere is defined, and having a stem (3) which extends from the level of the centre (2) of the sphere along a centre line (4) over a length (L) up to a distal end (5). Since the stem has a modulus of elasticity E of between 10 GPa and 60 GPa, since the length L lies between 50 mm and 150 mm and since the equivalent stiffness S=E L formed from the product of the modulus of elasticity E and the length L lies between 0.5·109 and 9·109 [Newton/metres], the stem behaves similarly to the bone material itself and the shear strains between the stem and the bone material are kept low.
