An anterior cervical plating system having moveable plate segments to vary the overall length of the plate, moveable to allow andor cause intersegmental compression of vertebral bodies, and coupled together by a non-detachable fastener. The invention solves the problems that the setting time is too long to cause bad mechanical property in conventional bone cements and also remains bioactivities and degradation ability. The invention further relates to an arrangement for carrying out said method. The nano-chain unit is a metallic structure with plasmon resonance absorption, where metallic nanoparticles are mutually linked with bottlenecks.
