Scientists Create Injectable Foam To Repair Degenerating Bones

Scientists Create Injectable Foam To Repair Degenerating Bones | Salud Publica | Scoop.it
Researchers in France have developed a self-setting foam that can repair defects in bones and assist growth. Eventually, this advanced biomaterial could be used to quickly regenerate bone growth and treat degenerative diseases such as osteoporosis.


Injectable calcium phosphate cements (CPCs) have been around for nearly a hundred years, and they’re frequently used in orthopedics and traumathology as bone substitutes during surgery. These biomaterials allow surgeons to fix and harden defective bones “in situ” with relative ease and flexibility. What’s more, they’re biocompatible, self-setting, and non-toxic. 


But as James Urquhart reports at Chemistry World, scientists haven’t been able to introduce macroporosity into these materials, which means these injectable cements don’t have pores, or cavities, larger than 50 nanometers. This makes it difficult to treat bone degeneration, or to strengthencancellous bone—a porous, flexible and spongy tissue that gets progressively weaker once osteoporosis sets in.


Now, Pierre Weiss and his colleagues at the University of Nantes have achieved an important breakthrough in this area. By applying a sophisticated hydrogen as a foaming agent to create air bubbles in the mixture, the researchers have created an effective macroporous, self-setting CPC. The results of their work appears in the latest edition of Acta Biomaterialia.

The e-Medicine Explosion

The e-Medicine Explosion | Salud Publica | Scoop.it

e-Medicine is on the rise. Medicine has perennially been stuck in the era of fax machines, but new technology and new laws are bringing innovation in mobile devices, data analytics, and telemedicine. This collection explores how the e-medicine explosion is changing the way we collect and use health information—and how businesses manage health-care costs.
