The Stryker Spine AVS® Anchor-L is an intervertebral body fusion device indicated for use with autograft and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft when the subject device is used as an adjunct to fusion in patients with degenerative disc disease (DDD) at one level or two contiguous levels from L2 to S1. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. DDD patients may also have up to Grade I spondylolisthesis at the involved level(s). These patients should be skeletally mature and have six months of nonoperative therapy. The AVS® Anchor-L Lumbar Cage system is to be implanted via an open, anterior approach. The AVS® Anchor-L Lumbar Cage system may be used as a stand-alone device or in conjunction with supplemental fixation. When used as a stand-alone device, the AVS® Anchor-L Lumbar Cage must be used with the internal screw and plate fixation provided by AVS® Anchor-L Fixation Screws and Locking Plate. If AVS® Anchor-L is used with less than three or none of the provided screws, then additional supplemental fixation that has been cleared by the FDA for use in the lumbar spine must be used to augment stability. The accompanying Locking Plate must be used anytime the device is used with any number of screws.
