Claims11
A method of treating a patient, comprising:
- providing a glenoid implant comprising a body portion having (i) a smooth concave lateral articulating surface adapted to be engaged by a humeral component, (ii) a medial surface adapted for positioning within a circular cavity reamed in a glenoid surface of a patient, (iii) a circumferential peripheral edge in the shape of a circle extending around the body portion, and (iv) a central peg extending coaxially from a center of the medial surface, wherein the body portion is cylindrically shaped and, wherein the circumferential peripheral edge defines a cortical-bone-contacting surface;
- reaming a circular cavity into the glenoid surface wholly within a boundary of a native glenoid cavity of the patient without destroying a peripheral margin of the glenoid surface;
- and
- inserting the glenoid implant into the circular cavity, such that the circumferential peripheral edge of the body portion resides below the adjacent glenoid surface, wherein the circumferential peripheral edge of the body portion lies directly adjacent to and is circumferentially surrounded by cortical bone of the glenoid.
