Abstract
The connection of the facing ends of a tubular bone cut by an operation consists of a cylindrical metal pin with an open-cell metallic outer layer on a cylindrical metal core and with annular grooves for receiving stop surfaces which come to bear against the bone ends. The stop surfaces are suitably formed as flat interrupted rings of circumference slightly greater than half the circumference of the annular grooves and arranged to project outwardly of the grooves. A longitudinal groove intersects the annular grooves and receives a longitudinal flange projecting outwardly of the longitudinal groove and connected to the stop surfaces. The connection may be used as an endoprosthesis in which case only one stop surface is employed.
