In their latest study, experts evaluated new titanium-based alloys containing gallium additions with the aim of offering beneficial antibacterial properties while having a reduced stiffness level to minimize discomfort when in contact with bone.

The findings are published in the Journal of Functional Biomaterials.

“The alloys in this work have shown very promising results and are part of ongoing efforts to improve components in orthopedic implants,” says Dr. Reza Hashemi, a Senior Lecturer in Mechanical Engineering at Flinders University’s Tonsley campus.

“Compared to existing prostheses, the addition of gallium produces a superior material with antibacterial properties to improve patient outcomes while reducing potential pain, medical complications and long-term implant failure.”
