Usually, we would use titanium or steel screws and plates to fasten the bones when you suffer from fracture. However, these small foreign matters may cause irritation or discomfort in your body. Luckily, a new biological ceramics screws developed by Fraunhofer IFAM, other famous universities and hospital will end this situation. This screw is made of calcium phosphate or hydroxyapatite which are basically the same as the essential of human bones, thus it could replace those metal parts being used at present. This new screw and bones could fuse together, and the screw need not to be moved out. The technology was shown at MEDICA 2016 on Nov. 14^th to 17^th 2016 in Dusseldorf.

The project is funded by Federal Ministry of Education and Research and the reach funding is €1 million. The researchers said that the main task was to make the screws meet the characters of ceramics and also hard. Different from titanium screws or polymer screws, this screws with new materials is not being screwed to bones, but being hammered carefully into bones. Thus, the researchers specially developed a new thread which could let the screw be easily hammered into bones. This could not only reduce injuries of muscle tendon and bones of patients, but also shorten the duration of anesthesia.
