This systematic review pools 9 studies and 239 total shoulder arthroplasties performed on B2 (biconcave) glenoids. It compares three techniques for correcting glenoid retroversion: asymmetric reaming, posterior bone-grafting, and posteriorly augmented glenoid components. The goal was to establish a baseline understanding of outcomes and complication rates for this difficult reconstructive problem.
