The present invention relates to provisional prosthetic components for a
medical device and the surgical methods for utilizing the same. In one
embodiment, the provisional prosthetic component includes a first portion
and a core. The first portion is capable of mating with another
prosthetic component. The first portion of the provisional prosthetic
component may have a scratch hardness which is less than the scratch
hardness of the prosthetic component. This allows for the first portion
to be placed in mating engagement with the prosthetic component without
scratching or damaging the junction of the prosthetic component.
Additionally, the core of the provisional prosthetic component may have a
scratch hardness greater than the scratch hardness of the first portion
of the provisional prosthetic component and/or a stiffness sufficient to
minimize deflection of the provisional prosthetic component during trial
reduction and range of motion testing.
