Solar-ST M PSI (Anterior, Standalone, With Integrated Fixation) and Solar-A T M PSI Spacers (Anterior, Non-Standalone, With Integrated Fixation)
The Solar-STM PSI (Standalone) and Solar-AT M PSI (Non-Standalone) are lumbar interbody fusion devices intended for use at one or more levels of the lumbosacral spine (Li-S1) in patients with degenerative disc disease (DDD), disc herniation (myelopathy and/or radiculopathy), spondylolisthesis or retrolisthesis, 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 had at least six (6) months of non-operative treatment. Solar-S T M PSI and Solar-A T M PSI Spacers are to be filled with autograft bone and/or allogenic bone graft composed of cancellous and/or corticocancellous bone.
Solar-STM PSI 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 one or more levels.
Hyperlordotic interbody devices (200 lordosis) used with screws or tusks, must always be used with supplemental fixation, and may be used at one or more levels.
When used with supplemental fixation, all Solar-S TM PSI Spacers used with screws or tusks may be used at one or more levels.
Solar-A M PSI:
These devices are intended to be used at one or more levels 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 (200 lordosis) must be used with at least anterior supplemental fixation.
Solar-MTM PSI Spacers (Anterior, Without Integrated Fixation)
Solar-MTM PSI 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 (L1-S1) as an adjunct to fusion in patients with the following indications: degenerative disc disease (DDD), disc herniation (with myelopathy and/or radiculopathy), spondylolisthesis or retrolisthesis, 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 had at least six (6) months of non-operative treatment. Solar-MTM PSI 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.
ImpulseT PSI Spacers (Posterior / Transforaminal)
The ImpulseT PSI is an intervertebral body fusion device intended for use in skeletally mature patients with Degenerative Disk Disease (DDD) of the lumbar spine with up to Grade 1 Spondylolisthesis at one or more levels in the lumbosacral spine ([1-S1) as an adjunct to fusion. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. The ImpulseT PSI is indicated to be used with autograft and/or allograft comprised of cancellous and/or corticocancellous bone graft to facilitate fusion and are intended to be used with supplemental fixation systems cleared for use in the lumbar spine. The device is to be used in patients who have had six months of nonoperative treatment.
