Glenosphere with inserts for augmented fixation and related methods

Abstract

An insert component includes an insert body and a cavity defined within the insert body. The insert body includes a first surface, a second surface spaced from the first surface, and a third surface. The second surface cooperates with the first surface to define at least one first channel configured to receive an engagement member. The third surface has a first and second surface end each extending from a perimeter of the first surface. A curved portion of the third surface between the first surface end and the second surface end extends into the insert body. The cavity includes a first cavity opening defined by the first surface. The cavity defines a first cavity region and a second cavity region each coextensive with a third cavity region. The first cavity region and second cavity region each have a cavity diameter greater than a diameter of a plate engagement member.
