INTERVERTEBRAL SPINAL IMPLANT DEVICES AND METHODS OF USE

摘要

A spinal implant device (10) used for the surgical treatment of a spinal disorder. The implant device may be a static device or a dynamic device. In one embodiment, the implant device is constructed of a radiolucent material with attached radiopaque markers (42a, 42b, 42). The markers may be constructed of the same radiolucent material and a radiopaque additive. In one embodiment, the implant device is constructed of a carbon nanostructure reinforced polymer. In one embodiment, the implant device has a porous bone interface surface. The pore density of the bone interface surface may vary up to a larger value in areas where the bone interface surface contacts a cortical bone portion of a vertebra.
