A glenoid component apparatus for shoulder arthroplasty, the apparatus comprising:

• a bearing portion configured to engage a bearing element associated with the humerus;
• and
• a stem portion connected to said bearing portion;
• wherein said stem portion models a normalized glenoid vault morphology,
• wherein said stem portion includes a plurality of mutually substantially parallel triangular cross sections that are spaced apart along a dimension of said stem portion, and
• wherein said plurality of mutually parallel triangular cross sections includes:
• a first triangular cross section having a width and having a depth about 2.8 times the width;
• a second triangular cross section having a width about 2.2 times the width of the first triangular cross section and having a depth about 2 times the width of the first triangular cross section;
• a third triangular cross section having a width about 2.2 times the width of the first triangular cross section and having a depth about 1.8 times the width of the first triangular cross section;
• a fourth triangular cross section having a width about 1.7 times the width of the first triangular cross section and having a depth about 2 times the width of the first triangular cross section;
• and
• a fifth triangular cross section having a width about equal to the width of the first triangular cross section and having a depth about 2.2 times the width of the first triangular cross section.
