Intended Use

The Denali Spinal System is a non-cervical spinal fixation device intended for posterior, non-pedicle fixation for the following indications: degenerative disc disease ( DDD ) (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies ); spondylolisthesis; trauma ( i.e. fracture or dislocation ); spinal stenosis; curvatures ( i.e. scoliosis, kyphosis, and/or lordosis); tumor; pseudoarthrosis; and failed previous fusion. The Denali Spinal System is also intended for non-cervical pedicle screw fixation for the following indications: trauma ( i.e. fracture or dislocation ); spinal stenosis; curvatures ( i.e. scoliosis, kyphosis, and/or lordosis); tumor; pseudoarthrosis; and failed previous fusion. It is also indicated for the treatment of severe spondylolisthesis ( grades 3 and 4 ) of the L5-S1 vertebra in skeletally mature patients receiving fusion by autogenous bone graft having implants attached to the lumbar and sacral spine ( L3 to sacrum ) with removal of the implants after the attainment of a solid fusion.

Device Story

Denali Spinal System is top-loading, multi-component posterior spinal fixation system. Components available in various sizes to match patient anatomy. System functions as adjunct to fusion to provide immobilization of thoracic, lumbar, and sacral spinal segments. Used by surgeons in clinical/OR settings to stabilize spine. Provides mechanical support to facilitate fusion; implants typically removed after solid fusion achieved. Benefits include spinal stabilization and correction of deformities.

Clinical Evidence

Bench testing only; no clinical data provided.

Technological Characteristics

Top-loading posterior spinal fixation system. Materials: Ti6Al-4V ELI alloy per ASTM and ISO standards. Components include pedicle screws and rods. Non-active, mechanical device.

Indications for Use

Indicated for skeletally mature patients requiring non-cervical spinal fixation (posterior non-pedicle or pedicle screw) for degenerative disc disease, spondylolisthesis (including severe grades 3-4 at L5-S1), trauma (fracture/dislocation), spinal stenosis, spinal curvatures (scoliosis, kyphosis, lordosis), tumor, pseudoarthrosis, or failed previous fusion.

Regulatory Classification

Identification

A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome.
