A bidirectional fixating intervertebral implant system includes at least one implant body, a perimeter enclosure, and first and second anchors. The at least one implant body has first and second vertebral body-facing surfaces with first and second sets of ridges. The first and second vertebral body-facing surfaces define first and second anchor openings. The perimeter enclosure extends around a body perimeter of the implant body. The implant body and the perimeter enclosure are sized to fit within a disc space. The perimeter enclosure defines at least one tool hole. The first and second anchors are sized and configured to extend through the first and second anchor openings. The first and second anchors have first and second shaft portions and first and second vertebral body engagement portions extending laterally outward from the first and second shaft portions, respectively, in multiple directions.
