As the figures at the top of this post indicate, the B2 glenoid can managed with a ream and run procedure.
As the figures below demonstrate, the B2 glenoid can also be managed with a standard all polyethylene glenoid and anatomic humeral head.
The preoperative axillary view shows the humeral head to be posteriorly decentered on the retroverted glenoid.
Comment: While preoperative 3D CT based planning software may suggest the need for augmented glenoid components to "correct" joint geometry, most arthritic shoulders with B2 glenoid pathoanatomy can be durably managed with anatomic arthroplasty using standard components, accepting the glenoid retroversion (see this related post on correctors and acceptors).
