Abstract
The figures show a cementable shaft prosthesis ( ) comprising a centering apparatus ( ) of plastic which can be pushed on at its distal shaft end ( ) and which forms a cavity ( ) to the distal shaft end ( ). Between the distal shaft end ( ) and the centering apparatus ( ) there exists a clamping connection which enables a deeper sinking in of the shaft end into the cavity in the distal direction. The clamping connection is achieved by a spigot ( ) which is formed on at the centering apparatus ( ) in the cavity ( ) and which protrudes in into a conical bore ( ) of the shaft end ( ) in the proximal direction.
