Read the full statement (167 words)

When intended to promote fusion of the cervical spine and occipito-cervico-thoracic junction (occiput - T3), the MOUNTAINEER Occipito-Cervical-Thoracic (OCT) Spinal System is intended for:

* ODD (neck pain of discogenic origin with degeneration of the disc as confirmed by patient history and radiographic studies)

* spondylolisthesis

* spinal stenosis

* fracture/dislocation

* atlanto/axial fracture with instability

* occipitocervical dislocation

* revision of previous cervical spine surgery

* tumors

The occipital bone screws are limited to occipital fixation only.

The use of the monoaxial and polyaxial screws is limited to placement in the upper thoracic spine (T1-T3) in treating thoracic conditions only. They are not intended to be placed in the cervical spine.

The Songer Cable System, to be used with the MOUNTAINEER OCT Spinal System, allows for wire/cable attachment to the posterior cervical spine.

The MOUNTAINEER OCT Spinal System can also be linked to the ISOLA®, TiMX®, MONARCH®, EXPEDIUM®, VIPER® and MOSS® MIAMI Systems using the dual wedding band and axial connectors, and via dual diameter rods.

Indications for use as stated in the FDA summary.
