What is it indicated for?
The ASTRA-OCT Spine System implants are intended to provide immobilization and stabilization of spinal segments as an adjunct to fusion for the following acute and chronic instabilities of the craniocervical junction, the cervical spine (C1-C7) and the thoracic spine (T1-T3): • Traumatic spinal fractures and/or Traumatic dislocations; • Instability or deformity; • Failed previous fusions (e.g. pseudoarthrosis); • Tumors involving the cervical/thoracic…
Read the full statement (185 words)
The ASTRA-OCT Spine System implants are intended to provide immobilization and stabilization of spinal segments as an adjunct to fusion for the following acute and chronic instabilities of the craniocervical junction, the cervical spine (C1-C7) and the thoracic spine (T1-T3):
• Traumatic spinal fractures and/or Traumatic dislocations;
• Instability or deformity;
• Failed previous fusions (e.g. pseudoarthrosis);
• Tumors involving the cervical/thoracic spine; and
• Degenerative disease, including intractable radiculopathy and/or myelopathy, neck and/or arm pain of discogenic origin as confirmed by radiographic studies, and degenerative disease of the facets with instability.
The ASTRA-OCT Spine System implants are also intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the cervical spine in whom life expectancy is of insufficient duration to permit achievement of fusion.
In order to achieve additional levels of fixation, the ASTRA-OCT Spine System rods may be connected to other occipital cervical thoracic or thoracolumbar stabilization rod systems ranging in diameter from 3.5mm to 6.35mm, including the ASTRA or APEX Spine Systems, using corresponding connectors.
Indications for use as stated in the FDA summary.
