The Chena Cervical Peek Spacer System is an anterior cervical interbody fusion device indicated for use in skeletally mature patients with degenerative disc disease (DDD) with accompanying radicular symptoms at one level or two contiguous levels from C2-TI. DDD is defined as discogenic pain with degeneration of the disc confirmed by history and radiographic studies. These patients should have had six weeks of non-operative treatment. The Chena Cervical Peek Spacer interior should be packed with autogenous bone graft and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft and implanted via an anterior approach. The Chena Cervical Peek Spacer is intended to be used with supplemental fixation.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
