Summary
We compared the different methods of primary fixation available within the glenoid components: cemented triangular keel, round backed and flat-backed, two cemented pegs, uncemented expansion screws. The implants were subjected to pull-out and eccentric load tests in a bone substitution material: a polyurethane foam loaded with aluminium. Experimental validation obtained from the measurements taken on the cadaveric specimens allowed us to make the following conclusions: (a) primary implant fixation was superior for the cemented implants during the tests, (b) the presence of cement beneath the tray added stability, (c) the cemented triangular keel had better fixation than the cemented pegs.
