  • Publication number: 20110208318
    Abstract: A removable prosthetic element having an elongated stem with a smooth outer surface, a portion of which defines, when the element is implanted in a subject, a contact interface between the stem and surrounding bone and/or fibrous tissue. One or more longitudinal guide channels in the form of longitudinal circular bores are located to the interior of the outer surface of the stem, the bore being adapted for receiving and laterally retaining a drill bit. One or more anchoring cavities comprising pores or passages having an opening with a distal perimeter at the outer surface of the stem lead to a longitudinal guide channel. At least a portion of the distal perimeter is formed as a sharp or pointed cutting edge that cuts the ingrown tissue upon upward removal of the element.
