"An AP glenoid view (tangential to baseplate) is needed to assess for scapular notching, which will allow visualisation of the glenosphere and scapular neck without humeral prosthesis superimposition 1."
"Grade 3 and 4 scapular notching are thought to be result of polythene-induced osteolysis as mechanical impingement is unlikely to occur past the inferior screw. If erosion results in prosthesis instability, a revision arthroplasty may be required 1,2."
