Joint endoprosthesis and method for assembling such a prosthesis

摘要

A prosthesis, in particular a shoulder prosthesis, includes a socket part receiving a joint head; an anchoring part anchoring the prosthesis in a bone; and a connecting arrangement securely connecting the socket part to the anchoring part. The socket part is assigned at least one pin and the anchoring part has at least one guide. The guide is designed in such a way that the pin can be held substantially safe from tilting in the guide.

1. A prosthesis, comprising:
a socket part receiving a joint head on a pan thereof, the socket part including a plurality of pins extending away from a side of the socket part opposite the pan so that, when inserted into a target portion of bone, the socket part is non-rotatably secured thereto, each of the pins including a locking feature on an outer surface thereof; and an anchoring part which, when implanted, anchors the prosthesis in a bone, the anchoring part including a plurality of guides formed to receive the pins therein to couple the socket part to the anchoring part in an essentially tilt-proof manner, each of the guides including a locking structure engaging a corresponding one of the locking features, the locking structure projecting into the respective guide, the guides having a first length and the pins having a second length less than the first length so that a distal portion of a first one of the guides receives a portion of a first fastening component that extends past a distal end of the first guide.
