## Introduction
The junction between the skull (occiput) and the cervical spine is the most complex and mobile area of the skeleton. In cases of massive trauma or instability, the **Occipito-Cervico-Thoracic (OCT) Fixation System** is used to bridge the skull to the neck and upper back.
## Critical Components of the OCT System
Stabilizing the “Head-to-Neck” connection requires specialized hardware:
* **Occipital Plates:** High-strength titanium plates that are screwed directly into the thickest part of the skull.
* **Polyaxial Cervical Screws:** Used in the lateral masses of the cervical vertebrae.
* **Thoracic Pedicle Screws:** To anchor the bottom of the long construct in the stable thoracic spine.
* **Rods and Connectors:** Precision-engineered rods that transition from the cervical (3.5mm) to the thoracic (5.5mm) sections.
## Technical Specifications
Ortholyx OCT systems are designed for extreme durability:
1. **Material:** Grade 5 Titanium (Ti6Al4V) for the best strength-to-weight ratio.
2. **Low Profile:** The occipital plate is ultra-thin to prevent skin breakdown at the base of the skull.
3. **Multi-axial heads:** Provide 60掳 of freedom to accommodate the unique angles of the craniocervical junction.
## Clinical Success
OCT fixation is a “salvage” procedure that requires meticulous planning. Ortholyx provides the complete instrumentation needed to safely navigate the delicate anatomy of the vertebral arteries and the spinal cord during these life-saving procedures.
## Conclusion
The OCT system is the ultimate test of orthopedic engineering. By providing a stable bridge between the skull and the spine, Ortholyx helps surgeons restore stability to patients with the most severe cervical injuries.
