Abstract: A shoulder arthroplasty kit includes a combination sizer and guide device with a base portion including a rim configured to be positioned against a resected surface of a humerus. A cavity which is configured to receive a mounting portion of a humeral base component extends proximally from the base portion, the cavity. The combination sizer and guide device includes a convex outer surface which replicates at least a part of an outer bearing surface of a humeral head component. A bore which is perpendicular to the distal plane extends between the cavity and the convex outer surface. The kit further includes a guide pin with a maximum diameter sized to fit within the bore such that the guide pin is guided by the bore during insertion of the guide pin into the resected surface of the humerus.

Abstract: A method of implanting a humeral component includes accessing a humerus and resecting a head portion of the humerus to form a resected surface. The method further includes selecting a first combination sizer and guide device having an outer surface sized complementary to a desired implant head size, positioning the selected first combination sizer and guide device on the resected surface, guiding placement of a guide pin in the humerus with the first combination sizer and guide device, guiding a reamer with the placed guide pin to form a reamed cavity in the humerus, positioning an anchoring portion of a humeral implant base portion in the reamed cavity, positioning the first combination sizer and guide device on the base portion, removing the first combination sizer and guide device from the base portion, and positioning an implant head on the base portion.

Abstract: A shoulder arthroplasty system in one embodiment includes a combination device including a base portion defining a distal plane, a cavity extending proximally from the base portion, the cavity configured to receive a mounting portion of a humeral base component, a convex outer surface, the convex outer surface sized to replicate at least in part an outer bearing surface of a humeral head component, and a bore extending between the cavity and the convex outer surface, and a guide pin sized to fit within the bore.
