The Walch B2 glenoid is characterized by a biconcave glenoid deformity, acquired glenoid retroversion, and posterior humeral head subluxation. Surgical reconstruction of the B2 glenoid remains a challenge. Surgical management options include arthroscopic debridement, hemiarthroplasty, anatomic total shoulder arthroplasty with eccentric reaming, bone grafting or augmented glenoid implants, and reverse total shoulder arthroplasty. Multiple factors dictate the optimal surgical management strategy. This article describes each of these techniques and presents the current available literature in an effort to guide evidence-based decisions in the surgical management of the B2 glenoid deformity.
