## Indications for use
When used as an intervertebral body fusion device, the system is intended for spinal fusion procedures at one or two contiguous levels (L2-S1) in skeletally mature patients with degenerative disc disease (DDD). 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 1 spondylolisthesis or retrolisthesis at the involved level(s). These patients may have had a previous nonfusion spinal surgery at the involved spinal level(s). These patients should have had six months of nonoperative treatment. The device is intended to be used with autogenous bone graft and/or allogeneic bone graft composed of cancellous and/or corticocancellous bone and supplemental fixation.
