Biomechanical characteristics of bioabsorbable magnesium-based (MgYREZr-alloy) interference screws with different threads

Abstract

Biomechanical testing showed higher pull-out forces for magnesium compared with a commercial polymer screw. Hence, they suggest better stability and are a potential alternative. The thread geometry does not significantly influence the stability provided by the magnesium implants. This study shows the first promising results of a degradable material, which may be a clinical alternative in the future.
