When used with or without the CONDUIT™ Lateral Switch Plate, the EIT Cellular Titanium® LLIF Cage is indicated for use with supplemental spinal fixation systems cleared by the FDA for use in the lumbar spine.
The EIT Cellular Titanium® LLIF Cage with a microscopic roughened surface and micro and nano-scale features is indicated for intervertebral body fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2-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 spinal implants are to be used with autogenous bone graft and/or allogeneic bone graft comprised of cancellous and/or corticocancellous bone graft. EIT Spine LLIF is to be used with supplemental fixation. Patients should have at least six (6) months of non-operative treatment prior to treatment with an intervertebral cage.
Indications for use as stated in the FDA summary.
