IO^™ Lateral Expandable Interbody

The IO™ Lateral Expandable Interbody is indicated for intervertebral body fusion procedures in skeletally mature patients with degenerative disc disease (DDD) of the lumbar spine at one or two contiguous levels from L1-L2 to L5-S1.  DDD is defined as discogenic back pain 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).   Devices are to be used with autogenous and/or allogenic bone graft and supplemental fixation.  Patients should have at least six (6) months of non-operative treatment prior to treatment with an intervertebral body fusion device.
