Abstract

To determine the effectiveness of hybrid glenoid components in reducing the frequency of glenoid component loosening, we evaluated clinical and radiographic outcomes at a minimum 2-year follow-up in 35 shoulders using a system with a central porous titanium post to augment the cemented pegs. Function was evaluated with the American Shoulder and Elbow Society score, QuickDASH disability score, and active shoulder range of motion. Postoperative radiographs were analyzed for radiolucent lines, progressive loosening, and at-risk signs. The average American Shoulder and Elbow Society score improved from 39 to 80 (P<0.0001), the average QuickDASH score from 52 to 19 (P<0.0001), forward elevation from 109 to 144 degrees (P<0.001), and internal rotation from 42 to 55 degrees (P=0.01). Mean external rotation improved from 38 to 42 degrees (P=0.19). Radiographs showed glenoid component radiolucency in 17, radiolucencies confined to the area under the glenoid faceplate in 5, and partial radiolucencies around the central post in 12. None of the implants had multiple column involvement and no components were determined to be at risk. There was no glenoid component failure or revision for loosening. Although there were statistically significant improvements in clinical and functional outcomes at 2 years, over a third of components demonstrated radiolucent lines.
