A glenoid component for a shoulder prosthesis adapted to be mounted in a
glenoid cavity of a shoulder. An elongated keel adapted to engage with
the glenoid cavity is attached to the internal surface of the base. The
keel extends along a longitudinal axis of the base. The keel includes
various configurations of transverse members extending away from the
longitudinal axis. The surgeon selects a glenoid component with a keel
and transverse member configuration that is anatomically optimized for
the patient. Glenoid components properly optimized provide mechanical
strength and stability superior to prior art devices. The glenoid
components disclosed herein are particularly well suited for use in an
anatomical total shoulder prosthesis, but may are also suited to partial
shoulder prostheses and reverse shoulder prostheses.
