Abstract

Glenoid component loosening is the most common early mode of failure of total shoulder arthroplasty (TSA) We hypothesised that the use of a pegged glenoid component with a modern glenoid reaming system and an instrumented cement pressurization technique would achieve a low prevalence of early radiolucent lines. Of 81 patients having TSA with a cemented, all polyethylene, 3-peg glenoid component for primary glenohumeral osteoarthritis, 69 had high quality radiographs available for analysis. All preoperative and initial postoperative radiographs were reviewed and graded in a blinded manner using previously established criteria. When the radiolucency grade of cement fixation was converted to a numeric scale of 0 (no radiolucency) to 5 (grossly loose), the mean cementing score was 0.14 + 0.06. Of the 69 shoulders, 62 (90%) had no radiolucencies. These techniques to improve glenoid fixation resulted in a low incidence of early radiolucencies about the glenoid component in patients having TSA for primary glenohumeral osteoarthritis.
