Title: Ceramic implant

Abstract: A ceramic implant having at least one component for permanently connecting resected live bone stumps without the use of bone cement or the insertion of an endoprostheses portion into the intramedullar or marrow space of the bone, the implant including at least one cylindrical sleeve having a truncated conical interior recess with rounded grooves helically formed therein for closely engaging a cooperatively formed live bond stump. The ceramic sleeve may be held to the bone stump by use of surgical screws or by a sleeve clamp, to provide a high degree of strength to the resected bone end, as compared to the natural bone strength, immediately after the implanatation operation and to reduce the cortical periphery encased by the implant to promote maximum natural bone growth with minimal inflammation and damage to the marrow space.
