A stem component having a body portion and a connection portion is
provided. A portion of the stem component may be fitted to a cavity in a
canal of a long bone. The stem component includes a canal portion and a
sleeve portion that has an internal periphery that forms an internal
cavity. A portion of the external periphery of the sleeve portion may be
fitted to the cavity of the long bone. A portion of the external
periphery of the connection portion may be fitted into the internal
cavity of the sleeve portion, so that the external periphery of the
connection portion of the joint component is spaced inwardly from the
external periphery of the sleeve portion of the stem component when the
joint component is fixedly connected to the stem component so that the
joint component may be removed without disturbing the fixation to the
long bone.
