Chronic instability led to early osteoarthritis with osteophytes in the infero-medial humeral head. b Radiograph of a left shoulder showing GHA using three cannulated screws with washers transfixing the glenohumeral joint. Fusion to the acromion was avoided. Post-operative CT scan of the left shoulder showing successful gleno-humeral fusion in coronal (left) and axial views (right)
