As shown in the figure at the top, the B2 can be managed using a reaming and running procedure.
As shown in the following figures, the B2 can be treated with a standard polyethylene glenoid.
The preoperative axillary image shows that the humeral scapula is decentered posteriorly on the retroverted, glenoid.
Comment: The majority of arthritic shoulders that have B2 glenoid anatomy can be managed durably with anatomic arthroplasty, using standard components and accepting the glenoid reversion (see the related post about correctors vs acceptors).
