SHOULDER PROSTHESIS AND COMPONENTS THEREOF

摘要

The present disclosure relates to a shoulder prosthesis comprising a glenoidal component having a glenoidal articulation surface and a humeral component having a humeral articulation surface, and a separate mobile glenohumeral bearing component comprising a glenoidal bearing surface and a humeral bearing surface arranged on opposite sides of the glenohumeral bearing component. The glenoidal bearing surface contacts in an implanted state the glenoidal articulation surface and/or the humeral bearing surface contacts in an implanted state the humeral articulation surface. At least one of the glenoidal and humeral bearing surfaces is concave. The glenohumeral bearing component is disposed in an implanted state between the glenoidal component and the humeral component. Both the glenoidal and humeral articulation surfaces are convex.

1. A shoulder prosthesis comprising:
a glenoidal component having a glenoidal articulation surface; a humeral component having a humeral articulation surface; and a separate mobile glenohumeral bearing component comprising a glenoidal bearing surface and a humeral bearing surface arranged on opposite sides of the glenohumeral bearing component, wherein the glenohumeral bearing component is disposed, in an implanted state, between the glenoidal component and the humeral component such that at least one of the glenoidal bearing surface and the humeral bearing surface contacts the corresponding glenoidal articulation surface or humeral articulation surface; wherein at least one of the glenoidal and humeral bearing surfaces is concave; and wherein both the glenoidal and humeral articulation surfaces are convex.
