The patented Anchor Peg Glenoid achieves immediate stability with the three minimally cemented peripheral pegs and provides a proven method3 of fixation through an interference fit of the central peg. The central peg facilitates bony integration around the flutes for increased fixation strength and resists “rocking horse” loosening1. 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 study1.
The Anchor Peg Glenoid is available in PREMIERON™ X-Linked Polyethelene - the brand name for our moderately cross-linked polyethylene.
