Abstract
A reverse shoulder replacement system including a humeral liner defining a split curvature bearing surface that includes a plurality of curvature regions. The plurality of curvature regions are configured to engage a glenosphere of a glenoid implant individually or in combination to provide an improved fit between the glenosphere and the humeral liner.
Claims20
A method for reverse replacement of a shoulder joint, comprising:
- inserting a stem of a humeral implant into a humerus;
- mounting a humeral liner to an end of the stem, wherein the humeral liner defines a split curvature bearing surface including a plurality of curvature regions including at least:
- a first curvature region having a first curvature, and
- a second curvature region having a second curvature different than the first curvature;
- selecting a glenosphere from a plurality of glenospheres including at least one glenosphere having a first curved exterior surface that corresponds to the first curvature and at least one glenosphere having a second curved exterior surface that corresponds to the second curvature;
- and
- mounting the selected glenosphere to a glenoid region of a scapula.

A method for reverse replacement of a shoulder joint, comprising:
- mounting a humeral implant to a humerus;
- securing a humeral liner to the humeral implant, wherein the humeral liner defines a split curvature bearing surface including a plurality of curvature regions including at least:
- a first curvature region having a first curvature, and
- a second curvature region having a second curvature different than the first curvature;
- selecting a glenoid implant from a plurality of glenoid implants including at least one glenoid implant having a first curved exterior surface that matches the first curvature of the first curvature region and at least one glenoid implant having a second curved exterior surface that matches the second curvature of the second curvature region;
- and
- mounting the selected glenoid implant to a glenoid region of a scapula.

- securing a humeral liner to the humeral implant, wherein the humeral liner defines a split curvature bearing surface including a plurality of curvature regions including at least:
- a first curvature region defined by a first curvature, and
- a second curvature region defined by a second curvature different than the first curvature;
- selecting a glenoid implant from a plurality of glenoid implants including at least one glenoid implant having a first glenoid bearing surface defined by a first diameter that corresponds to the first curvature and at least one glenoid implant having a second glenoid bearing surface defined by a second diameter that corresponds to the second curvature;
- and
- mounting the selected glenoid implant to a glenoid region of a scapula.
