Abstract

A stemless implant for shoulder arthroplasty includes a body having a proximal portion, distal portion, and an outer surface. A cylindrical extrusion is substantially perpendicular to and adjacent the proximal portion. At least a portion of the outer surface is configured to contact bone, the outer bone contacting surface comprising a concave taper. The stemless implant can be sized and shaped for insertion into a metaphysis of a humerus bone without penetrating a diaphysis of the humerus bone. The implant optionally comprises a medial fin, a lateral fin, an anterior fin, and a posterior fin. The medial fin and lateral fin may be thicker than the anterior fin. The fins may taper from the proximal portion to the distal portion.
