The glenosphere implants are available in two diameters,
38 mm and 42 mm, and are either standard or eccentric
spheres.
An overlap of 3 to 5 mm below the glenoid inferior limit is
recommended to avoid scapular pillar conflict (Figure 70).
Depending on the glenoid pillar shape, this overlap can be
achieved using the standard glenosphere, just by lowering
the metaglene. if the size of the joint (once exposed)
allows, it is recommended to use the 42 mm glenosphere.
The eccentric glenospheres are recommended for more
vertical pillars.
