Assemble the internal rod of the metaglene holder in the
metaglene holder main body. insert the metaglene holder
hex tip in the final metaglene implant central hole. Lock
the assembly by screwing the internal rod tight (Figure
33).
place the metaglene on the glenoid and ensure that the
metaglene is fully seated on bone. Apply bone graft if
necessary to help fill any surface irregularities between
the metaglene and the glenoid bone. identify the
rotational orientation that enables the inferior screw to be
contained within the inferior pillar of the scapula. check
that the vertical metaglene marking is aligned with the
scapular pillar inferiorly and with the coracoid process
base superiorly (long axis of the glenoid) (Figure 34).
The metaglene peg is slightly oversized to enable a press
fit. gently impact with light mallet blows in the proper
orientation for inferior screw placement and remove the
metaglene holder.
