use the same manual glenoid reamer to also ream the
glenoid anteriorly, posteriorly and inferiorly if necessary. A
smooth surface without any remaining cartilage should be
obtained.
Check the adequacy of reaming by applying the glenoid
reaming level checker to the glenoid surface. No space
should be seen between the instrument and the glenoid
surface unless this is due to bone erosion (Figure 30).
Remove the resurfacing reamer, leaving the metaglene
central guide pin in place (Figure 31).
connect the cannulated stop drill to the power tool and
drill the central hole over the guide pin until full contact
between the drill and bone is obtained (Figure 32).
Remove the stop drill and the central guide pin.
