Rationale for shorter humeral components

Preserved bone stock	• Bone stock for fixation of periprosthetic humerus fracture • Bone stock at time of a future revision
No stress shielding	• Most proximal humeral bone is loaded
No diaphyseal stress riser	• Stress riser is in trabecular metaphyseal bone • No diaphyseal reaming
Ease of stem removal	• Proximal access to implant bone interface
Humeral head placement independent from orthopedic axis	• Allows alignment in deformity surgery
