N2 - Tantalum coated carbon fiber reinforced carbon (C-C) cages for spinal fusion offers excellent bone ongrowth and inherent X-ray marking while preserving the desirable properties of the C-C substrate: Strength, toughness, low E-modulus, and radio translucency. The X-ray translucency is preserved by applying a uniform 0.5μm tantalum coating. A pilot series of spinal cage implants was manufactured from tantalum coated C-C and tested with respect to mechanical properties and diagnostic compatibility as well as by implantation. Mechanical testing demonstrated adequate strength of the implant for carrying the load of the spine and withstanding the force applied during surgery. Compatibility with diagnostic imaging techniques was demonstrated for radiology, CT and MRI. Some artifacts were seen on MR images in the proximity of the metal-coated implant preventing imaging the implant surface. Implantation confirmed biocompatibility, bone ongrowth and compatibility with radiology and CT-scanning, both producing clear images of the implant and the bone inside. Copyright
