The Signature Orthopaedics Freedom Cervical Screw and Rod System is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients (C1 to C7) as an adjunct to fusion in the treatment of the following acute and chronic instabilities and deformities of the cervical spine:
* traumatic spinal fractures and/or traumatic dislocations
* instability or deformity; failed previous fusions (e.g. pseudarthrosis)
» degenerative disease, including neck and/or arm pain of discogenic origin as confirmed by radiographic studies, and degenerative disease of the facets with instability, and
* short term stabilization 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 expectancy is of insufficient duration to permit achievement of fusion.
