The patented GLOBAL® Anchor Peg Glenoid achieves immediate stability with the three cemented peripheral pegs, and provides a proven method of fixation through an interference fit of the central peg. A study by Wirth et al. showed that mean fixation strength increased significantly within three months and remained strong six months postoperatively in a weight-bearing animal study. Improved fixation was confirmed radiographically and histologically, and the central fluted peg achieved bone ingrowth in all cases.
