Researchers found the incidence of scapular notching in reverse shoulder arthroplasty was reduced as a result of the inferior offset glenosphere created by a glenosphere base plate design, particularly when the glenosphere was maximally offset inferiorly.
The researchers retrospectively reviewed the charts of 82 patients who underwent reverse shoulder arthroplasty with an eccentric glenosphere. Patients’ mean age was 74 years, and mean follow-up period was 26.3 months. Cuff tear arthropathy was an indicator for surgery for 63 patients, acute and chronic trauma was an indicator for five patients and revision total shoulder arthroplasty was the cause for surgery in 14 patients.
