• a head member having a first articulating surface and a second fixation surface opposite said first articulating surface, said first articulating surface operable to engage the articulating surface of the glenoid component and said second fixation surface being adapted to be secured to a fixation component;
• and
• said fixation component having a first surface adapted to be secured to said second fixation surface of said head member and a second surface which is generally opposite the first surface, said second surface having a fixation member adapted to be secured to the humerus wherein said fixation component defines a plurality of holes positioned about a perimeter of said fixation component, each operable to receive a bone screw.
