## Indications for use
The Tritanium® X PL Expandable Posterior Lumbar Cage and Tritanium® X TL Expandable Curved Posterior Lumbar Cage are intended for intervertebral body fusion 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. These DDD patients may also have up to Grade I spondylolisthesis or retrolisthesis at the involved level(s). These patients should be skeletally mature and have completed six months of non-operative treatment. Additionally, the Tritanium® X PL Expandable Posterior Lumbar Cage and Tritanium® X TL Expandable Curved Posterior Lumbar Cage can be used as an adjunct to fusion in patients diagnosed with degenerative scoliosis. The Tritanium® X PL Expandable Posterior Lumbar Cage and Tritanium® X TL Expandable Curved Posterior Lumbar Cage are always to be used with supplemental internal spinal fixation. Additionally, the Tritanium® X PL Expandable Posterior Lumbar Cage and Tritanium® X TL Expandable Curved Posterior Lumbar Cage are to be used 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.
