Patent attributes
A glenoid system (100) includes a baseplate (102) configured to attach to a glenoid cavity of a patient. In a primary configuration, a biocompatible plastic liner (332) can snap into a circumferential groove (120) on the baseplate, to attach to a lateral facing surface (104) of the baseplate, at one or more locations around the groove. In a reverse configuration, a glenosphere (544, 644) can attach to an adapter (542, 642), which in turn can attach to the lateral-facing surface of the baseplate. The adapter can introduce lateral and/or angular offsets between the baseplate and the glenosphere, which can correct for unwanted offsets or inclinations. A middle peg extension (752) can screw onto a medial end of the middle peg (114), which can offer different combinations of peg length and peg material. The baseplates can be made available in various discrete sizes, each of which has the same distance between the middle peg and an inferior screw hole (112).
