Humeral prosthetic implants (100, 200, 300, 400), systems, kits and methods of forming the humeral prosthetic implants, systems and kits are disclosed. The humeral prosthetic implants include proximal cup portions (110, 210, 310, 410) and distal stem (140, 230, 330, 440) portions, wherein the proximal cup portion is joined to the distal stem portion at a desired offset and/or angle configured based on an analysis of the humeral diaphysis and/or metaphysis offset in a patient. The humeral prosthetic implants may also include an adapter (160, 250, 350, 460) configured to join the proximal cup component with the stem component, wherein the adapter is configured to join the stem component to the stemless cup at a desired offset and/or angle.
