Abstract: A method for preparing an articulating component of a joint prosthesis having an implant engaged within a bone of the joint, the method including inserting a first articulating component into a first insert in the implant within the bone of the joint, determining an angular orientation of the inserted first articulating component relative to the implant within the bone of the joint, positioning a second articulating component within a second insert component, replicating the angular orientation of the first articulating component in the second articulating component positioned within the second insert, fixing the second articulating component to the second insert component at the replicated angular orientation, and mounting the second insert component with the fixed second articulating component to the implant engaged within the bone of the joint.

Abstract: A joint prosthesis includes a bone engaging portion, such as a stem, and articulating component, such as a humeral head, and an insert component that supports the articulating component and is removable from the stem. A mating component mates with the humeral head and is configured to engage the insert component at adjustable angles according to the anatomy of the patient's joint. In a revision surgery, the stem remains within the patient's bone while the insert component is removed with the mating component and humeral head fixed to the insert component. A new insert component may be prepared with the mating component and humeral head oriented to replicate the angular orientation of the previous prosthesis. The new insert component is then mounted within an insert cavity in the implanted stem and rigidly fastened to complete the revision.

Abstract: A trial implant system includes a stem component and an articulating component forming part of a joint of a patient. A trial mounting assembly mounts the articulating component to the stem component at variable relative angular positions. The trial mounting assembly includes an expandable ball portion and an expansion element configured to expand the ball portion upon rotation of the expansion element. In an expanded state, the ball portion contacts a cavity within the stem at three points of contact to fix the center of rotation of the ball portion at a pre-determined location within the stem. The stem cavity defines an inwardly projecting circumferential lip that bears against ball portion as it expands to ensure the three-point contact.
