The present invention relates to an endoprosthesis for a shoulder joint having a stem member ( 10 ), extending axially along a first axis ( 100 ), with a distal end piece ( 11 ) insertable into the humerus of a patient and a proximal end piece ( 12 ), a stem head ( 20 ) being provided on the proximal end piece ( 12 ). In order to be able to achieve an anatomically optimum metaphyseal fit of the endoprosthesis in a simple way, according to the invention the stem member ( 10 ) and the stem head ( 20 ) are in each case constructed as modular components which are introducible into the patient's body separately from one another during implantation of the endoprosthesis, the stem member ( 10 ) having a connecting element ( 13 ) at its stem-head-side proximal end ( 12 ) and the stem head ( 20 ) having at its humeral, distal end ( 22 ) a distal connecting element ( 23 ) correspondingly constructed so as to be complementary thereto, which connecting elements can be brought into engagement with one another and in the implanted state of the endoprosthesis co-operate with one another so that a force-based connection is formed between stem member ( 10 ) and stem head ( 20 ). |
