Sacroplasty Safe and Effective to Reduce Low Back Pain

...and others have adapted techniques developed for vertebroplasty in the lumbar spine. In vertebroplasty, physicians use fluoroscopic guidance to inject polymethylmethacrylate (PMMA) into osteoporotic compression fractures. After injection the acrylic bone cement hardens. The technique was designed to stabilize the fracture,...

Scientists create tough ceramic that mimics mother of pearl

...mic ever produced. Through the controlled freezing of suspensions in water of an aluminum oxide (alumina) and the addition of a well known polymer, polymethylmethacrylate (PMMA), a team of researchers has produced ceramics that are 300 times tougher than their constituent components. The team was led by Robert Ritchie, ...
