## Indications for use
Solar-S™ (Standalone, With Integrated Fixation) and Solar-A™ (Non-Standalone, With Integrated Fixation) The Solar-S™ (Standalone) and Solar-A™ (Non-Standalone) are lumbar interbody fusion devices intended for use in patients with degenerative disc disease (DDD) at one or two contiguous levels of the lumbosacral spine (L2-S1). DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. In addition, these patients may have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). These patients should be skeletally mature and have had at least six (6) months of non-operative treatment. Solar-S™ and Solar-A™ ALIF Spacers are to be filled with autograft bone and/or allogenic bone graft composed of cancellous and/or corticocancellous bone. * Solar-S™ Used With Screws or Tusks: When used with three (3) screws, interbody devices with a lordotic angle < 20° can be used as standalone interbody fusion devices at 1 or 2 contiguous levels. When used with three (3) tusks, interbody devices must always be used with supplemental fixation and may be used at 1 or 2 levels. Hyperlordotic interbody devices (>20° lordosis) used with screws, must always be used with supplemental fixation, and may be used at 1 or 2 levels. * Solar-A™: These devices are intended to be used with supplemental fixation systems that have been cleared for use in the lumbosacral spine (e.g., posterior pedicle screw and rod systems, anterior plate systems, anterior screw and rod systems). Hyperlordotic interbody devices (>=20° lordosis) must be used with at least anterior supplemental fixation. Solar-M™ ALIF Spacers (Without Integrated Fixation) Solar-M™ ALIF Spacers are lumbar interbody fusion devices indicated at one or more levels of the thoracic spine (T1-T12), thoracolumbar junction (T12-L1), or lumbosacral spine (L.1-S1) as an adjunct to fusion in patients with the following indications: degenerative disc disease (DDD), disc herniation (with myelopathy and/or radiculopathy), spondylolilsthesis, deformity (degenerative scoliosis or kyphosis), spinal stenosis, and failed previous fusion (pseudarthrosis). 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 has at least six (6) months of non-operative treatment. Solar-M™ ALIF Spacers are to be filled with autograft bone and/or allogenic bone graft composed of cancellous and/or corticocancellous bone. These devices are intended to be used with supplemental fixation systems that have been cleared for use in the thoracolumbosacral spine (e.g., posterior pedicle screw and rod systems, anterior plate systems, anterior screw and rod systems). Hyperlordotic interbody devices (=20° lordosis) must be used with at least anterior supplemental fixation.
