SYMPHONY OCT System—Compartment 2

Richard Bransford, Maarten Spruit

The SYMPHONY OCT System is an enhanced set of instru­ments and implants for posterior fixation of the occipital-cer­vical junction, subaxial spine, and cervico-thoracic junction. Compartment 1 of the SYMPHONY OCT system was launched in November 2019, and was described in the 2019 issue of the Innovations magazine (Innovations Magazine 2019)

SYMPHONY Compartment 1 has recently been supplemented by enhanced and innovative elements (Compartment 2) to further address surgical needs and avoid pitfalls in complex cervical surgery. Launched in early 2021, the Compartment 2 components include MULTIPOINT SECURE (Fig 1) to augment lateral mass screws, reduction screws, advanced connector and various rod designs, a short drill guide and polydriver. This additional feature builds on the advanced features already found in Compartment 1 taking the best of Synthes Synapse and DePuy Mountaineer.

By optimizing and improving instruments and implants for posterior cervical fusion (PCF) following FATE principle (fixation, alignment, targeting, and extension), Compartment 2 also addresses surgical and technical concerns in an aging pop­ulation with suboptimal bone quality and in patients who may require stronger constructs meeting the indications for spinal fusion.
