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 bone clamp for coupling an intramedullary stem to a bone includes a collet, a bushing, and a cap. The collet includes a main body and a plurality of legs and is configured to receive the bone and the intramedullary stem. The collar includes internal threading that is complementary to external threading on the main body of the collet such that rotation of the collar relative to the collet translates the collar to compress the plurality of legs radially inwardly against the bone. The bushing is received within the collet, and the cap includes internal threading that is complementary to external threading on the proximal end of the collet such that rotation of the cap relative to the collet translates the cap distally relative to the collet to compress the bushing against the intramedullary stem.

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 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.

Abstract: An orthopedic screw includes a main body having a torqueing end, an inner chamber formed therein, and at least two mating features separated by a separation gap, the separation gap extending into the inner chamber, at least one of the at least two mating features having a first tapered portion with an increasing width and a second tapered portion with a decreasing width; and a support member removably placed in the inner chamber of the main body and having a support portion at least partially filling the separation gap between the at least two mating features.
