Abstract

The intramedullary stem is provided with a plurality of recesses in the wide sides which are disposed in herring bone fashion. These recesses communicate with a longitudinal groove so that bone tissue material may move into the recesses and grooves during implantation. Apertures may also be provided through the stem so as to provide spaces for the tissue material to collect in a packed manner. Each recess also has a domed shaped pocket on the upper side to receive the material during implantation.
