Abstract: A humeral prosthesis for replacing a proximal humerus includes a prosthesis body which includes a lateral surface, a medial surface, an anterior surface, a posterior surface, and a first superior surface. The lateral surface has a spherical curvature. The anterior and posterior surfaces are each planar and each intersect the first superior surface, the lateral surface, and the medial surface. A first bore extends through the first superior surface and into the prosthesis body. The prosthesis body also includes a plurality of suture openings.

Abstract: A trial humeral prosthesis may include a trial stem for implantation into a humerus, and a trial proximal body configured to couple to a trial articulating component. A plurality of trial spacers may be configured to couple the trial stem to the trial proximal body, the plurality of trial spacers including a first trial spacer and a second trial spacer. The first and second trial spacers may each include a proximal post and a tab extending radially outward from the proximal post, and a distal body having a larger outer diameter than an outer diameter of the proximal post, a slot being formed in the distal body. The slot of the distal body of the first trial spacer may be configured to receive the tab of the second trial spacer when the proximal post of the second trial spacer is received within the distal body of the first trial spacer.

Abstract: A prosthetic trial base includes a hinge and two levers connected to one another by the hinge. Each lever includes a tab extending proximally of the hinge and a fin extending distally of the hinge. The prosthetic trial base also includes a head movable between the tabs to force the tabs apart from one another. The trial base also includes a collar defining a bore in which the tabs are received and a lid that is connected to the levers. The head and is connected to the lid in a manner that enables the head to be driven relative to the lid.
