Background Posterior glenoid wear remains a challenge in anatomic and reverse total
shoulder arthroplasty (rTSA) because of an asymmetric erosion with altered retroversion …

Background: Posterior glenoid erosion is thought to be initiated by humeral head
subluxation. However, it is unknown whether subluxation is entirely caused by soft-tissue …

Background The purpose of this computed tomography–based study was to quantify
erosions in B2 glenoids. We hypothesized that erosions do not occur symmetrically and that …

Background Anatomic factors associated with static posterior translation of the humeral head
with or without glenohumeral osteoarthritis are unknown. We tested the hypothesis that there …

Background Eccentric glenoid bone loss patterns (B-and C-type glenoid) pose a difficult
challenge when performing shoulder arthroplasty. Anatomic total shoulder arthroplasty with …

Aims This study aimed to assess the impact of using the metal-augmented glenoid
baseplate (AGB) on improving clinical and radiological outcomes, as well as reducing …

Background Glenoid bone loss in anatomic total shoulder arthroplasty (aTSA) remains a
controversial and challenging clinical problem. Previous studies have shown high rates of …

Glenoid bone deficiency and eccentric posterior wear are difficult problems faced by
shoulder arthroplasty surgeons. Numerous options and techniques exist for addressing …

Eccentric posterior glenoid erosion is a common condition in osteoarthritis. No limits have
ever been placed on the degree of eccentric erosion that can be corrected while still …

Background Type B glenoids according to Walch are subclassified into a group with no
posterior erosion (B1) and a group with important posterior erosion (B2) based on 2 …
