What is it indicated for?

The Z-LINKPC 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 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…

Read the full statement (185 words)

The Z-LINKPC 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 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. These 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.

To achieve additional levels of fixation, the Z-LINKPC System may be connected to the Zavation Spinal System using rod connectors and tapered rods.

When used with the occipital plate, the Z-LINKPC System is also intended to provide immobilization and stabilization for the occipito-cervico-thoracic juction (occiput-T3) in treatment of the instabilities mentioned above, including occipitocervical dislocation.

Indications for use as stated in the FDA summary.
