University of Toledo (Ohio) researchers developed a smart injectable calcium phosphate bone cement for orthopedic and spinal fusion applications. The smart CaP compositions were biocompatible, according to a study in Materials.
Here are four things to know:
1. Researchers incorporated piezoelectric barium titanate particles into monetite-based CPC composition.
2. They aimed to take advantage of BT's piezoelectric properties since electromechanical effect plays a role in defect site fracture healing bone integration with the implant.
3. The BT addition led to positive compressive strength, injectability, bioactivity, biocompatibility and washout resistance.
4. Incorporating BT did not compromise the bone cements' self-setting nature.
