Patent ID: 8080063

Claim:
A glenoid component for a shoulder prosthesis adapted to be mounted in a glenoid cavity of a shoulder, the glenoid component comprising: a base comprising an external articulating surface having a continuous arcuate profile configured to cooperate in an anatomical manner with a hemispherical humeral head and an internal surface adapted to engage with the glenoid cavity of the shoulder; an elongated keel attached to the internal surface of the base and extending along a longitudinal axis of the base, the keel having a proximal end and a distal end and being adapted to engage with the glenoid cavity; and one or more transverse members extending away from the longitudinal axis of the base, the transverse members comprising a maximal proximal-distal dimension less than a dimension between the proximal end and the distal end of the keel and a length less than about half a length of the keel when measured along the longitudinal axis, the transverse members including at least one generally planar surface adapted to contact and engage the glenoid cavity, wherein the generally planar surface is spaced at a distance from the internal surface of the base, and wherein the generally planar surface is oriented generally parallel to the external articulating surface.
