Glenoid Retroversion

One of the most common complications of total shoulder arthroplasty (TSA) is glenoid component loosening due to implant-cement fixation failure. High cement stresses resulting in fracture are believed to result from malpositioning the glenoid implant [1]. Ideal glenoid preparation and placement, however, are not always achievable due to significant anatomical alterations caused by arthritis resulting in posterior glenoid erosion and increased glenoid retroversion. To our knowledge, prior research has not compared the effects of insufficient reaming depth and incomplete version correction on the likelihood of cement mantle failure. The purpose of this study was to investigate how the degree of correction of the glenoid vault affects cement mantle stress and potential cement failure.

Glenoid Retroversion

The Walch B2 glenoid is characterized by a biconcave glenoid deformity, acquired glenoid retroversion, and posterior subluxation of the humeral head. Surgical reconstruction of the B2 glenoid is often challenging due to the complexity of the deformity. Bone graft augmentation using humeral head autograft is a valuable adjunct to anatomic total shoulder arthroplasty in the B2 glenoid, particularly in the young, highly active patient with severe glenoid retroversion (>25°–30°). Although this technique affords the ability to correct glenoid version and simultaneously enhances glenoid bone stock, it is technically challenging. The potential for graft-related complications also exists, which may further impact glenoid implant longevity and functional outcome. This review article aims to describe the B2 glenoid morphology, discuss the challenges in managing the B2 deformity, and provide further insight specifically regarding autografting at the time of anatomic total shoulder arthroplasty for reconstruction of the B2 glenoid.
