Bone Screws are placed in human bone to repair a fracture. In most cases, a second surgery is required to remove the bone screw to allow further healing. There is fantastic research going on around the world on new bioabsorbable material based bone screws. The University of North Carolina Charlotte is making great strides in discovering the mechanical properties of their
bioabsorbable material. ADMET manufacturers Torsion Testing Systems and Biaxial Testing Systems to test these new materials to determine strength, durability, flexibility and more. In addition, news coming from the
University of Bremen states that their new material will revolutionize the bone screw market. What’s so special? The bioceramic screw is almost identical in its chemical composition as the main inorganic component of bone, i.e. calcium phosphate. And to top this – it can be produced by means of an innovative powder injection-moulding technique.

Ultra high molecular weight polyethylene is not only fun to say, but it is also an incredibly versatile material commonly used as a bearing surface in joint replacements. Polyethylene has low friction, good fracture toughness and fatigue resistance. However, there are several reasons for it's failure in clinical studies. New evidence suggests Read more...
