Estimating the term…
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 expand 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.
A trial implant for the joint of a patient, comprising:
An improvement for a trial implant for the joint of a patient, the trial implant including a stem component configured for placement within a bone of a patient, an articulating component configured for articulating contact with a mating aspect of the joint and a mounting assembly for mounting the articulating component to the stem component at variable angular orientations, the improvement comprising:
A method for establishing an angular orientation of an articulating component of an implant for the joint of a patient relative to a stem component configured for placement within a bone of a patient, comprising the steps of:
