Radiolucencies of partially cemented glenoid not linked with degree of component seating
Recently published results showed no correlation between radiolucencies around a partially cemented glenoid and the degree of component seating after total shoulder arthroplasty.
Researchers used a partially cemented all-polyethylene glenoid prosthesis in 36 unconstrained total shoulder arthroplasties performed in 29 patients for primary glenohumeral osteoarthritis (OA). Patients had a minimum 2-year follow-up, according to researchers, and were evaluated with standardized plain films preoperatively and postoperatively and with thin-cut CT scans at latest follow-up. Using the Lazarus and Yian classifications, researchers assessed radiolucency and seating on radiographs and CT scans.

Results showed no association between Lazarus plain film radiolucency scores or Yian CT radiolucency scores with Lazarus plain film seating scores at a mean of 43 months. Similarly, researchers found modified Lazarus CT scan seating scores were not associated with either Lazarus plain film radiolucency scores or Yian CT radiolucency scores. According to results, better intraobserver and interobserver reliability in all categories were found with CT. – by Casey Tingle
