Intended Use / Indications for Use
The Curiteva Porous PEEK Standalone ALIF devices are 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. 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 I spondylolisthesis or retrolisthesis at the involved level(s). The system spacers are intended to be used with autograft and/or allograft bone (comprised of cancellous and/or corticocancellous bone graft) or a bone void filler as cleared by FDA for use in intervertebral body fusion to facilitate fusion.
The Curiteva Porous PEEK Standalone ALIF spacer is an interbody fusion device to be used with three titanium alloy screws or anchors. When used with screws, the system is a standalone interbody fusion device. When used with anchors, the system is intended for use with supplemental fixation (e.g. facet screws or posterior fixation). Hyperlordotic implants (>20° lordosis) are intended for use with supplemental fixation (e.g. facet screws or posterior fixation).
The Curiteva Porous PEEK ALIF devices are intended for use 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, deformity (degenerative scoliosis or kyphosis), spinal stenosis, and failed previous fusion (pseudarthrosis). DDD is defined as discogenic back pain with degeneration of the disc as confirmed by history and radiographic studies. These patients should be skeletally mature and have had at least six (6) months of non-operative treatment. The system spacers are intended to be used with autograft and/or allograft bone (comprised of cancellous and/or corticocancellous bone graft) or a bone void filler as cleared by FDA for use in intervertebral body fusion to facilitate fusion. 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, and anterior screw and rod systems). Hyperlordotic interbody devices (>20° lordosis) must be used with at least anterior supplemental fixation.
