The DePuy Synthes Spine SYMPHONY™ Occipito-Cervico-Thoracic (OCT) System is an enhanced set of instruments and implants, including polyaxial screws, 3.5 mm and 4.0 mm rods, compatible hooks, cross connectors, lateral offset connectors, and rod connectors designed to address unmet needs in fixation alignment, targeting, and extension (FATE) for posterior stabilization of the upper spine. The implants provide the flexibility required to accommodate variations in patient anatomy.

The DePuy Synthes Spine SYMPHONY OCT System is compatible with occipital fusion components (plates, rods and clamps) from the SYNAPSE™ OCT System and the MOUNTAINEER® OCT Spinal System. Additionally, tapered rods and connectors are available to extend constructs to utilize both the DePuy Synthes Spine EXPEDIUM® and VIPER® Spine Systems.

Fixation in Varying Bone with Anatomically Designed Screws and Thread forms

    • 48.2%1 increased pullout strength in bone
    • Designed to anchor constructs in suboptimal bone††
  • Individual thread forms designed specifically to match varying anatomy for fixation in the lateral masses and pedicles
    • Cortical Fix threads available
    • 3.0 to 5.5 mm diameters
    • 92 degrees cone of angulation for non-cannulated Lateral Mass Screws
    • Quick-Start Tip for Lateral Mass Screws designed to optimize thread-to-bone engagement

†MULTIPOINT SECURE™ Adapter with 2 screw fixation as compared to lateral mass screw fixation alone
††The SYMPHONY OCT System is contraindicated for osteoporosis and relatively contraindicated for osteopenia
