The Stryker Spine AVS® AS PEEK Spacers are indicated for use in cervical interbody fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one level from the C2-C3 disc to the C7-T1 disc. DDD is defined as neck pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The AVS® AS PEEK Spacers are to be used with autogenous bone graft and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft, and are to be implanted via an open, anterior approach.

The AVS® AS PEEK Spacers are intended to be used with supplemental fixation systems that have been cleared for use in the cervical spine. This cervical device is to be used in patients who have had six weeks of non-operative treatment.

The Stryker Spine AVS® AS PEEK Spacer is a hollow, ring-shaped PEEK Optima® LT1 cage (per ASTM F2026) with three Tantalum marker pins (per ASTM F560). It is intended for use as an interbody fusion device of the cervical spine and is offered in a variety of lengths, heights, and lordotic angles to adapt to varying patient anatomies. The hollow, ring-shaped implant has serrations on the top and bottom for fixation. The hollow space of the implant is intended to hold bone graft material for fusion purposes.
