| 1. A glenoidal component for a reverse shoulder prosthesis that is adapted to secure to a surface of a glenoid cavity, the
glenoidal component comprising:
a base adapted to be secured to the surface of the glenoid cavity, the base comprising a mounting portion adapted to receive
a single element and a rear surface adapted to engage at least a portion of the surface of the glenoid cavity; and
a plurality of elements, each comprising a convex articular surface and a recess adapted to engage with the mounting portion
of the base, the convex articular surface comprising a non-spherical portion and a spherical portion with a geometric center
and an axis of symmetry that passes through the geometric center, wherein in an engaged configuration an offset between the
geometric center of the spherical portion and an axis of symmetry of the recess varies between at least two of the elements.
