Researchers at the University Medical Center and the Fraunhofer Institute in Aachen, Germany have teamed up to create a degradable bone implant that stimulates bone regeneration.  The material, a combination of polylactide and tricalcium phosphate forms a paste that hardens into a porous artificial bone.  The tricalcium phosphate stimulates natural bone growth and the implant degrades at the same rate as the bone regenerates.  MORE
