Abstract
The figures show a cementable shaft prosthesis (1) comprising a centering apparatus (2) of plastic which can be pushed on at its distal shaft end (3) and which forms a cavity (4) to the distal shaft end (3). Between the distal shaft end (3) and the centering apparatus (2) 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 (7) which is formed on at the centering apparatus (2) in the cavity (4) and which protrudes in into a conical bore (5) of the shaft end (3) in the proximal direction.
