Abstract

A femoral prosthesis system is provided which includes femoral prosthesis and an instrument for inserting/extracting the femoral prosthesis. The femoral prosthesis includes a stem and a neck portion. The stem includes a proximal end portion which defines a proximal stem axis. The neck portion is located proximally of the proximal end portion. The neck portion includes a proximal surface and an insertion/extraction cavity which extends distally from the proximal surface. The insertion/extraction cavity is configured to couple with the insertion/extraction instrument. The insertion/extraction cavity defines an insertion/extraction cavity axis which, when projected onto a coronal plane including the proximal stem axis, is not parallel with the proximal stem axis. The insertion/extraction instrument includes a distal end portion configured to couple with the insertion/extraction cavity.
