## Indications for use
When used as an Intervertebral Body Fusion device, the XY cor Expandable Spinal Spacer System is indicated for spinal fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies. These DDD patients may also have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). These patients should have had six months of non-operative treatment. The XY cor Expandable Spinal Spacer System is intended for use with autograft and with supplemental spinal fixation systems and that have been cleared by the FDA. When used as a Vertebral Body Replacement device, the XYcor Expandable Spinal Spacer System is intended for use in the thoracolumbar spine (T1-L5) to replace a collapsed, damaged or unstable partial or total vertebral body due to tumor or trauma (i.e. fracture). VBRs are designed to restore the biomechanical integrity of the anterior, middle and posterior spinal column, even in the absence of fusion for a prolonged period of time. The XYcor Expandable Spinal Spacer System is intended for use with autograft and/or allograft and with supplemental spinal fixation systems and that have been cleared by the FDA.
