Patent ID: 7854768

Claim:
A humeral implant for use in a total shoulder arthroplasty or a hemi shoulder arthroplasty, comprising: a stem portion extending toward a distal end thereof; a head portion at a proximal end thereof, said head portion including an internal head portion cavity having a head portion engagement structure and a first tapered bore; an articulating component receivable within said internal head portion cavity and including a component stem receivable within said first tapered bore, said articulating component including a component engagement structure engageable with said head portion engagement structure to axially secure said articulating component to said head portion when said component stem is received within said first tapered bore, said articulating component having a first surface opposite said component stem and a concave articulating surface extending from said first surface toward said component stem, said first surface defining a first angle with respect to a longitudinal axis of said stem portion, said first angle being between 55 degrees and 70 degrees; and a spacer including an internal spacer cavity having a spacer engagement structure and a second tapered bore on a first side of said spacer, said spacer including a spacer stem opposite said first side of said spacer, said spacer stem receivable within said first tapered bore, said spacer engagement structure engageable with said component engagement structure to axially secure said component to said spacer when said component stem is received within said second tapered bore, said spacer engagement structure dimensionally replicating said first head portion engagement structure so that said articulating component is selectively axially securable to said spacer and said head portion, said first tapered bore of said head portion dimensionally replicating said second tapered bore of said spacer so that said component stem of said articulating component is receivable in said first tapered bore and said second tapered bore, whereby said spacer is modularly attachable to said head portion and said articulating component.
