| 摘要 |
A spinal implant for insertion into an intervertebral disc space for intervertebral stabilization, the implant comprising a radiolucent polymer substrate coupled to a radiopaque and osseoconductive bone securing component which provides the implant with secure fixation between adjacent vertebrae. The implant's radiolucent, radiopaque and osseointegrative properties facilitate radiographic assessment of fusion across the disc space, assessment of osseointegration between vertebral endplates and osseointegration of the spinal implant to adjacent vertebral end plates. The implant comprises an implant substrate and a securing component coupled to the implant substrate. The implant preferably comprises a radiolucent polyetheretherketone (PEEK) substrate coupled to a radiopaque Titanium (Ti) or a titanium (Ti) alloy securing component, whereby the securing component is adjacent to the vertebral endplates when the implant is inserted in the disc space. The securing component comprises surface teeth or extension to secure the implant, within the intervertebral disc space to adjacent vertebrae.
