ALIF Cage with Anchor Placement Options

An anterior lumbar interbody fusion device having a plurality of anchor apertures shaped and arranged in ways that provide options as to the number and locations of fixation points that anchor the device securely to the vertebrae. The anchor apertures may be angled towards or away from the cage vertical midline and cage horizontal midline, as well as angled differently relative to each other. In addition, the proximal opening of the anchor aperture is slightly wider than the distal opening, which permits the anchor to be positioned at a desired pitch within the opening, as opposed to being limited to a single entry angle. In a preferred embodiment, the proximal and distal opening of the anchor aperture are obround and each anchor aperture is sized to receive two anchors. In a given placement, anchors may be placed in some or all of the anchor apertures in each cage.
