Glenoid Innovations in Shoulder Arthroplasty

Anatomic and reverse total shoulder arthroplasty have demonstrated reliable pain relief and improvement in function in select patient populations with glenohumeral arthritis. Certain scenarios have been associated with decreased longevity of the implant, inferior results, and increased complications including glenoid bone loss, revision arthroplasty, and glenoid arthrosis in the young, active patient. Multiple innovations exist to address these scenarios and have demonstrated early success. These innovations include augmented anatomic glenoid components, augmented reverse glenoid baseplates, and in-lay anatomic glenoid components. We review these glenoid innovations and provide case examples of each.
