Abstract
A humeral implant is disclosed. The implant has a humeral surface component and a stem. The humeral surface component has an articular surface and is configured for fixation to an articular portion of a proximal humerus. The stem is configured for post-surgery axial movement within the humerus. The stem is connected to the humeral surface component opposite of the articular surface. A method of implanting a humeral implant is also disclosed.
Claims17
A humeral implant comprising:
- an articular humeral component comprising an articular surface and configured for fixation to an articular portion of a proximal humerus;
- and
- a non-bone-adherent stem connected to the articular humeral component and configured for post-surgery axial sliding contact with a bone wall of a tunnel within the humerus to stabilize the stem against non-axial displacement and to prevent the stem from bearing a load from the articular humeral component applied in an axial direction.
A humeral implant comprising:
- an articular humeral component comprising an articular surface and configured for fixation to an articular portion of a proximal humerus;
- and
- an axially non-load-sheltering stem configured for post-surgery contact with a bone wall of a tunnel within the humerus to stabilize the stem against non-axial displacement, the stem connected to a side of the articular humeral component configured to face the proximal humerus, the stem comprising a non-bone-adherent surface.
