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.

About Posterior Cervical Fusion
Posterior Cervical Fusion is a procedure intended for the stabilization of the cervical spine through a posterior approach. The procedure is commonly performed using hooks, plates, screws and rods as an adjunct to the fusion. Posterior cervical fusion is performed to treat instabilities which arise from: degenerative disc disease, spondylolisthesis, spinal stenosis, fracture/dislocation, atlantoaxial fractures with insatiability, occipito-cervical dislocation, revisions of previous cervical spine surgery and tumors.(Source: Depuy Synthes)
