Claims19
A reverse shoulder orthopaedic implant, comprising:
- a humeral prosthesis including a humeral cup and an elongated stem component configured to be implanted into an intramedullary canal of a patient's humerus, and
- a glenosphere component having (i) a curved lateral bearing surface configured to articulate with the humeral cup of the humeral prosthesis, and (ii) a medial surface having a tapered bore formed therein,
- wherein the glenosphere component has (i) an anterior/posterior width defined by the distance between an anterior-most point of the lateral bearing surface and a posterior-most point of the lateral bearing surface, (ii) a superior/inferior width defined by the distance between a superior-most point of the lateral bearing surface and an inferior-most point of the lateral bearing surface, and (iii) the anterior/posterior width of the glenosphere component is greater than the superior/inferior width of the glenosphere component.

A reverse shoulder orthopaedic implant, comprising:
- a humeral prosthesis including a humeral cup and an elongated stem component configured to be implanted into an intramedullary canal of a patient's humerus, and
- a glenosphere component having a lateral bearing surface configured to articulate with the humeral cup of the humeral prosthesis, the lateral bearing surface being hemi-ellipsoidal in shape with its longitudinal axis extending in the anterior/posterior direction, and
- a metaglene component secured to the glenosphere component.
