This retrospective case series examines TSA with posterior glenoid bone grafting (PGBG) using humeral head autograft in 28 patients with glenohumeral osteoarthritis and severe posterior glenoid wear (retroversion −20° to −42°), asking whether this technique reliably corrects version and delivers durable clinical outcomes at minimum 2-year follow-up.
When you encounter a Walch B2 (or severe B1) glenoid with retroversion beyond ~15°–20° where eccentric anterior reaming would sacrifice excessive bone stock or risk vault penetration, PGBG with humeral head autograft is a reproducible alternative: the concave-convex match between the worn glenoid and resected humeral head creates a near-perfect interface, and this series shows reliable incorporation with durable version correction at 4 years.
Use an in-line keel or peg glenoid component — peripheral peg configurations are not compatible with this technique.
