Abstract
A method for implanting a reverse modular humeral implant into a humerus that includes a natural humeral shaft and a natural humeral head. The implant includes a humeral stem implantable into the natural humeral shaft, and an adapter couplable to the humeral stem, the adapter including an anchoring projection configured to be coupled to a convex bearing.
Claims20
A shoulder prosthetic comprising:
- a shoulder bearing having an articular surface and a glenoid component interface surface;
- a glenoid component having a mounting surface arranged to face a glenoid of a patient and an opposing bearing interface surface, a body of the glenoid component separating the bearing interface surface from contact with the patient's glenoid, wherein a stem extends from the mounting surface in a direction away from the bearing interface surface;
- and
- a spring disposed between the bearing interface surface of the glenoid component and the glenoid component interface surface of the shoulder bearing, wherein after implantation of the shoulder prosthetic, the spring member movably couples the shoulder bearing to the glenoid component and absorbs impact forces applied onto the shoulder bearing.

A shoulder prosthetic comprising:
- a shoulder beating;
- a glenoid component movably coupled to the shoulder bearing, the glenoid component having a body and a stem extending outwards relative to the body so as to be configured for insertion into a glenoid of a patient;
- and
- a spring interposed between the shoulder bearing and the glenoid component, wherein after implantation of the shoulder prosthetic, the spring absorbs impact forces applied onto the shoulder bearing, the body of the glenoid component defining a glenoid-interface surface arranged to separate the spring from the patient's glenoid so that the spring is disposed outside of the patient's glenoid.

A shoulder prosthetic comprising:
- a shoulder bearing;
- a glenoid component movably coupled to the shoulder bearing, the glenoid component having a body and a stem extending outwards relative to the body along a longitudinal axis so as to be configured for insertion into a glenoid of a patient, the stem being non-flexible along the longitudinal axis;
- and
- a spring interposed between the shoulder bearing and the glenoid component, wherein after implantation of the shoulder prosthetic, the spring absorbs impact forces applied onto the shoulder bearing.
