ABSTRACT:
A glenoid component for use in shoulder arthroplasty which 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 second textured medial surface opposite to the first articulating surface. The first articulating surface is adapted to be engaged by the head of the humeral component and the second textured medial surface is adapted to be secured to the scapula. A plurality of circular base members extends from the second textured medial surface and provides a circular base pad having a first diameter. A plurality of cylindrical pegs each have a first end adapted to engage a cavity formed in the scapula and a second end extending from one of the circular base members. Each of the cylindrical pegs is partially defined by a sidewall having a second diameter such that the first diameter of the cylindrical base pads is larger than the second diameter of the cylindrical pegs to increase peg shear strength.
