Read the full statement (343 words)

The ASTRA Spine System is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine.

The ASTRA Spine System is indicated for non-cervical (T1-S2/1lium) pedicle fixation and non-pedicle fixation in skeletally mature patients as an adjunct to fusion for the following indications: degenerative disc disease (DDD - defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies); severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra:; degenerative spondylolisthesis with objective evidence of neurologic impairment; trauma (i.e., fracture and/or dislocation); spinal stenosis; deformities (scoliosis, lordosis and/or kyphosis); spinal tumor; and failed previous fusion (pseudo-arthrosis).

When used in a percutaneous, posterior approach with AVANT Spine MIS instrumentation, the ASTRA Spine System is intended for non-cervical pedicle fixation for the following indications: degenerative disc disease (DDD - defined as discogenic back pain 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, pseudo-arthrosis, and failed previous fusion in skeletally mature patients . Levels of fixation are for the thoracic, lumbar and sacral spine.

When used for posterior non-cervical pedicle screw fixation in pediatric patients, the ASTRA Spine System implants are indicated as an adjunct to fusion to treat progressive spinal deformities (i.e., scoliosis, kyphosis, or lordosis) including idiopathic scoliosis, neuromuscular scoliosis, and congenital scoliosis. Additionally, the ASTRA Spine System is intended to treat pediatric patients diagnosed with the following conditions: spondylolisthesis/spondylolysis, fracture caused by tumor and/or trauma, pseudarthrosis, and/or failed previous fusion. These devices are intended to be used with autograft and/or allograft. Pediatric pedicle screw fixation is limited to a posterior approach.

The ASTRA fenestrated screw when used with other components of the ASTRA Spine System is indicated to provide the surgeon with an open or minimally invasive approach for posterior spinal surgery. The ASTRA fenestrated screw is intended to be used with saline or radiopaque dye.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
