ABSTRACT:
A fixation element for securing a prosthesis in a bone, whereby the effective diameter of the fixation element can be increased by increasing the temperature of at least one element of a material which shrinks or expands when heated, such as shape memory metal, by means of an inductive magnetic field, whereby the change in shape generated with the shrinkage or expansion of the material is converted into an increase in diameter of the fixation element.
