Shoulder arthroplasty implant system

An orthopedic system for shoulder arthroplasty, the system comprising:

• an implant including a stem having a proximal portion, a distal portion, an anterior portion, a posterior portion, a medial portion, and a lateral portion, wherein the stem has a size and shape for insertion into an intramedullary canal of a humerus bone, the humerus having a metaphysis and a diaphysis, the stem being arranged and configured for use in either of anatomic or reverse arthroplasty;
• an articular cup arranged and configured to be coupled to the stem;
• and
• a head component arranged and configured to be coupled to the stem;
• the implant further comprising:
• wherein the proximal portion of the stem comprises a concave taper decreasing in size in a direction extending from the proximal portion toward the distal portion, and
• wherein distal portion comprises a distal taper decreasing in size in a direction extending from the proximal portion toward the distal portion, and
• wherein the distal taper comprises a taper in a direction extending between the anterior portion and the posterior portion, and
• wherein the distal taper comprises a taper in a direction extending between the medial portion and the lateral portion, and
• wherein the shape of the stem is configured to apply a first load to the metaphysis portion of the humerus bone and apply a second load to the diaphysis portion of the humerus bone, the first load being greater than the second.
