ARTIFICIAL DISC IMPLANTS AND ASSOCIATED METHODS AND INSTRUMENTATION

摘要

An artificial disc implant (20) and associate methods and instrumentation are provided for the artificial disc implant (20) that includes opposite vertebral endplate members (30, 50) and a spacer member (22) between the vertebral endplate members (30, 50). An anchoring member (68) extends from at least one of the vertebral endplate members (30, 50) toward an adjacent vertebral endplate when the implant (20) is positioned between vertebrae. The anchoring member (68) can be received in an anchor seat (S) formed in the adjacent vertebral endplate without requiring the artificial disc implant (20) to be impacted into the space between vertebrae to engage the anchoring member (68) in the seat (S).
