The Symmetry Disc is an innovative spinal implant designed to replicate the natural motion of the cervical spine. Comprising two metal plates and a central plastic insert, it offers a bone-sparing approach to spinal disc replacement. The unique design allows the plates to remain securely attached to the vertebrae through teeth that press into the bone, eliminating the need for invasive keels or screws. This design minimizes surgical steps, making it a less disruptive option compared to traditional spinal implants, while the plastic insert moves with the patient’s neck to support natural motion.
The Symmetry Disc is typically used for patients undergoing disc replacement surgery, particularly for one or two-level cervical disc degeneration or herniation. It’s ideal for individuals who have experienced chronic neck pain or restricted movement due to damaged intervertebral discs, where traditional methods might involve more invasive procedures. Because of its self-adjusting nature, the Symmetry Disc can offer better alignment and mobility for patients, mimicking the natural function of the spine and helping to reduce long-term complications.
The implantation process of the Symmetry Disc is simplified for both the surgeon and the patient. Unlike traditional spinal implants that require bone chiseling or the insertion of screws, the Symmetry Disc can be inserted in a single step. The device comes preassembled on a PEEK cartridge, which allows for easy, precise placement. The implant’s radiolucent design ensures optimal positioning under imaging, and the bone-preserving technique results in faster recovery times and less disruption to surrounding tissue, providing a smoother surgical experience.
