What is it indicated for?

The PERLA® posterior occipito-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 crania-cervical junction, the cervical spine (Cl to C7) and the thoracic spine (T to T3): traumatic spinal fractures and/or traumatic dislocations; instability or deformity; failed previous fusions (e.g., pseudarthrosis); tumors involving…

Read the full statement (264 words)

The PERLA® posterior occipito-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 crania-cervical junction, the cervical spine (Cl to C7) and the thoracic spine (T to 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 occipito-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.

The occipital bone screws are limited to occipital fixation only. The use of the multi-axial screws is limited to placement in the cervical spine (CI to C7) and the thoracic spine (T1 to T3).

In order to achieve additional levels of fixation, the PERLA® posterior occipito-cervico-thoracic fixation system may be connected to the ROMEO®2 and PERLA® TL Posterior Osteosynthesis Systems with rod connectors. Transition rods may also be used to connect the PERLA® posterior occipito-cervico-thoracic fixation system to the ROMEO®2 and PERLA®TL Posterior Osteosynthesis Systems. Refer to the ROMEO®2 and PERLA®TL Posterior Osteosynthesis Systems packages inserts for a list of the ROMEO®2 and PERLA®TL Posterior Osteosynthesis Systems indications of use. PERLA® posterior occipito-cervico-thoracic fixation system is indicated for skeletally mature patients.

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