Claims24
A glenoid implant comprising:
- a bone fixation portion comprising a first side, an articular side, a first protruding element on the first side, and a front surface on the articular side, the bone fixation portion defines a first socket open on the articular side adjacent the front surface, the first protruding element arranged to engage a bone surface inside a glenoid cavity;
- an articulating portion comprising a wear-resistant articulating surface arranged for sliding contact upon an articulating humeral portion of a humerus, a rear side, a second socket open on the rear side, and a rear surface adjacent the second socket;
- and
- a coupling portion arranged to connect the bone fixation portion and the articulating portion, the coupling portion is engaged with the second socket of the articulating portion and the coupling portion is engaged with the bone fixation portion in the first socket to form a stable long-lasting but disengageable connection between the bone fixation portion and the articulating portion, the front surface of the bone fixation portion is behind the rear surface of the articulating portion.
