What is it indicated for?
The PERLA® posterior cervico-thoracic fixation 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 cervical spine (C 1 to C7) and the thoracic spine from Tl-T3: traumatic spinal fractures and/or traumatic dislocations; instability or deformity; failed previous fusions (e.g., pseudarthrosis); tumors involving the cervical spine; and degenerative…
Read the full statement (207 words)
The PERLA® posterior cervico-thoracic fixation 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 cervical spine (C 1 to C7) and the thoracic spine from Tl-T3: traumatic spinal fractures and/or traumatic dislocations; instability or deformity; failed previous fusions (e.g., pseudarthrosis); tumors involving the cervical 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 PERLA® posterior cervico-thoracic fixation 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. In order to achieve additional levels of fixation, the PERLA® posterior cervico-thoracic fixation system may be connected to the ROMEO® Posterior Osteosynthesis System with rod connectors. Transition rods may also be used to connect the PERLA® posterior cervico-thoracic fixation system to the ROMEO® Posterior Osteosynthesis System. Refer to the ROMEO® Posterior Osteosynthesis System package insert for a list of the ROMEO® Posterior Osteosynthesis System indications of use.
Indications for use as stated in the FDA summary.
