Total Shoulder Arthroplasty Biomechanical Testing of the Fixation of a New Glenoid Design

The Comprehensive® Shoulder Solutions’ Modular Hybrid Glenoid from Biomet is a revolutionary design for replacement of the glenoid in total shoulder arthroplasty. It provides three outer pegs and three central peg options for surgical implantation. In vitro testing of the Modular Hybrid Glenoid resulted in mean axial pull-out peak loads ranging from 209 to 303 lbf, mean inferior/superior shear peak loads from 383 to 460 lbf and mean anterior/posterior shear peak loads from 483 to 636 lbf.1 Based on the clinically proven design of the Bio-Modular® Glenoid, the Modular Hybrid Glenoid provides for enhanced fixation. Theoretically, solid initial fixation leads to fewer radiolucencies and thus fewer clinically loose components. The Modular Hybrid Glenoid offers a solution to the growing needs of an expanding total shoulder arthroplasty population.
