The ZSFab Lumbar lnterbody System is intended for lumbar interbody fusion. The devices are indicated for use at one or two contiguous levels in the lumbar spine from L2-S1, in skeletally mature patients who have had at least six months of non-operative treatment. The ZSFab Lumbar lnterbody System is indicated to treat lumbar degenerative disc disease (DOD) with up to Grade 1 spondylolisthesis or retrolisthesis at the involved spinal level(s). ODD is defined as back pain of discogenic origin with degeneration of the disc confirmed by imaging studies (radiographs, CT, MRI). Additionally, the ZSFab Lumbar lnterbody System can be used as an adjunct to fusion in patients diagnosed with degenerative scoliosis. The ZSFab lumbar lnterbody System is designed for use with autogenous and/or allogeneic bone graft comprised of cancellous and/or corticocancellous bone and/or demineralized allograft bone with bone marrow aspirate to facilitate fusion and to be used with supplemental fixation cleared for use in the lumbosacral spine.
