The Interwedge® Standalone Lateral is a standalone lateral lumbar interbody fusion device intended for use in patients with degenerative disc disease (DDD) at one or two contiguous levels of the lumbosacral spine (L1-S1). DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletally mature and have had at least six (6) months of non-operative treatment. In addition, these patients may have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s).
The Interwedge® Standalone Lateral is to be filled with autogenous bone graft and/or allogeneic bone graft composed of cancellous, cortical, and/or corticocancellous bone, and is to be used with the two titanium alloy screws which accompany the implant. Should a physician choose to use fewer than these two screws, additional supplemental fixation must be used to augment stability.
Indications for use as stated in the FDA summary.
