Revision glenoid device

A glenoid component, comprising:

• a base component including a planar upper circular rim defining a first plane, a receptacle opening to the first plane, a lower planar circular surface defining a second plane parallel to the first plane, and a conical outer wall extending from the upper circular rim to the lower planar circular surface;
• and
• an articulating component, the articulating component including
• an upper articulating surface,
• a lower coupling portion including a first portion configured to be inserted into the receptacle so as to be completely beneath the first plane, and
• an outwardly extending portion extending outwardly from the first portion along the first plane and located between the first portion and the upper articulating surface, the outwardly extending portion configured to be completely above the first plane when the first portion is inserted into the receptacle,
• wherein:
• the base component defines a maximum base component diameter along the first plane;
• the articulating surface defines a maximum articulating surface diameter along the first plane;
• the outwardly extending portion defines a maximum outwardly extending portion diameter along the first plane;
• the maximum outwardly extending portion diameter is greater than the maximum articulating surface diameter;
• and
• the maximum base component diameter is greater than the maximum outwardly extending portion diameter.
