Glenoid implant systems and methods of using the same

Abstract

A glenoid implant system includes an anchoring structure and a glenoid liner. The anchoring structure includes a base, a wall, and a ledge. The wall extends from a first surface of the base. The ledge extends generally along at least a portion of a first side of the wall, thereby forming an undercut. The wall has a slot formed in a second opposing side of the wall. The glenoid liner is configured to be removably coupled to the anchoring structure. The glenoid liner has a cap portion, a main body, and a deflectable finger. The main body extends from the cap portion and includes a lip configured to engage the undercut of the anchoring structure. The deflectable finger extends from the cap portion. The deflectable finger has a protrusion configured to engage the slot of the anchoring structure to aid in securing the glenoid liner to the anchoring structure.

1 . A glenoid implant system comprising:
