Abstract

A glenoid component used for shoulder arthroplasty is adapted to be implanted into a scapula and engaged by a head of a humeral component. The glenoid component includes a body having a first articulating surface and a second medial surface opposite to the first articulating surface. The first articulating surface is adapted to engage with a humeral head. A plurality of removable fixed pegs each have a first end adapted to engage a cavity formed in the scapula and a second end extending from the medial surface. A central peg fixation mechanism is provided that is configured to couple an optional central fixation peg to the medial surface.
