The Lateral Spine Truss System (LSTS) Interbody Fusion Device is indicated for use 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. Patients should have received 6 months of non-operative treatment prior to treatment with the devices. All LSTS Interbody Fusion Devices must be used with supplemental fixation and must be used with autograft and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft. Interbodies with 18° lordosis or greater must be used with the 4WEB Lumbar Spine Truss System Plating Solution (LSTS-PS) with integrated fixation. If using the 1-hole 4WEB LSTS-PS with integrated fixation, additional supplemental fixation is required (e.g. posterior fixation). These DDD patients may also have up to Grade I spondylolisthesis or retrolisthesis at the involved level(s).
