Is silicon nitride, a material used in the space shuttle stronger than PEEK? The answer is yes, and it also has antimicrobial properties, making it a win-win material in orthopaedics.

Salt Lake City-based Amedica is using silicon nitride in its implants, because it is stronger than PEEK and has better imaging characteristics than PEEK and titanium.
In a recent Amedica profile featured in MD+DI:
“Alongside silicone nitride’s strength and imaging characteristics, early clinical results suggest it also has antibacterial properties and the ability to support enhanced bone ongrowth,” explains Eric Olson, CEO and president of the company. Those properties of the material have been investigated in vivo in animal studies at Brown University (Providence, RI). Its antimicrobial property could be especially useful because infections resulting from orthopedic implants are common and expensive problems for hospitals. “Keep in mind that we saw this effect in the lab without using any kind of drug,” explains biomedical engineering professor Thomas Webster, PhD. “We are pretty excited about the potential to decrease bacterial growth without having to prescribe a drug.”
