This single-institution case series reports mid-term (mean 8.6 years) radiographic and clinical outcomes of aTSA with corrective high-side reaming — using a cemented, nonaugmented all-polyethylene glenoid — in 34 shoulders with Walch B2 glenoid deformities, asking whether this technique provides durable results at medium-term follow-up.
When planning aTSA for a B2 glenoid, prioritize achieving near-complete glenoid component seating (target ≥80–100%) with meticulous cement pressurization — intraoperative seating quality, not the degree of preoperative retroversion, is the primary modifiable determinant of mid-term implant survival.
If posterior humeral head subluxation recurs on early follow-up radiographs, treat this as an early warning sign for progressive glenoid loosening and tighten surveillance intervals.
