What is it indicated for?

Cortium is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion for the following acute and chronic instabilities of the craniocervical junction, cervical spine (C1 to C7) and the thoracic spine (T1 to T3): traumatic spinal fractures and/or traumatic dislocations; instability or deformity; failed previous fusions (e.g., pseudarthrosis); tumors involving the cervical/thoracic spine…

Read the full statement (171 words)

Cortium is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion for the following acute and chronic instabilities of the craniocervical junction, cervical spine (C1 to C7) and the thoracic spine (T1 to T3): traumatic spinal fractures and/or traumatic dislocations; instability or deformity; failed previous fusions (e.g., pseudarthrosis); 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.

Cortium 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.

In order to achieve additional levels of fixation, Cortium can also be connected to Momentum via transition rods or connectors. Please refer to the Momentum Instructions for Use for a list of indications for use.

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