What is it indicated for?
The Northstar OCT System is 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, cervical spine (C1-C7) and upper thoracic spine (T1-T3): • Traumatic spinal fractures and/or traumatic dislocations; • Instability or deformity; • Failed previous fusion (e.g. pseudoarthrosis); • Tumors involving the cervical/thoracic spine; •…
Read the full statement (177 words)
The Northstar OCT System is 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, cervical spine (C1-C7) and upper thoracic spine (T1-T3):
• Traumatic spinal fractures and/or traumatic dislocations;
• Instability or deformity;
• Failed previous fusion (e.g. pseudoarthrosis);
• Tumors involving the cervical/thoracic spine;
• 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 Northstar OCT System is 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.
The Northstar OCT System can also be linked to other SeaSpine Screw Systems including Mariner, NewPort, Sierra, Atoll, Daytona, Malibu, Mariner MIS, Mariner Outrigger, and Mariner Midline Systems with the use of transitional rods and/or transitional rod connectors.
Indications for use as stated in the FDA summary.
