The Posterior Occipitocervical Spine Screw System is a comprehensive fixation solution designed to stabilize the occiput through the cervical spine (Occiput–C1 to C7) in complex posterior fusion procedures. It provides rigid fixation, restores anatomical alignment, and supports long-term fusion in cases of craniovertebral junction instability and multi-level cervical pathologies.
The system includes posterior cervical screws (standard and partially threaded), occipital plates and clamps, connecting rods, fixation connectors, and laminar hooks, enabling surgeons to create versatile, patient-specific constructs. Engineered for strong fixation and precise alignment, it delivers reliable performance across the entire occipitocervical region.
The Posterior Occipitocervical Spine Screw System by Siora Surgicals Pvt. Ltd. is a precision-engineered spinal fixation solution designed to stabilize the occiput and cervical spine following posterior fusion procedures. It is used to restore anatomical alignment, provide rigid fixation, and promote solid bony fusion across the craniovertebral junction.
Manufactured from high-quality, biocompatible Titanium (Ti-6Al-4V ELI), the system combines mechanical strength, durability, and excellent imaging compatibility. Its anatomically designed components ensure optimal fit, reduced intraoperative adjustments, and reliable implant performance.
The system includes posterior cervical screws (standard and partially threaded), straight and pre-contoured rods, cross-links, connectors, occipital plates and clamps, occipital screws, cable connectors, occipital arch plates, and laminar hooks, enabling the creation of versatile, patient-specific constructs across the occipitocervical region.
Designed for ease of application and precise construct assembly, the system supports rigid fixation, controlled alignment, and optimal load distribution. It plays a critical role in stabilizing the craniovertebral junction while promoting long-term fusion and structural integrity. Backed by stringent manufacturing standards, Siora Surgicals Pvt. Ltd. ensures consistent quality, dependable performance, and reliable clinical outcomes.
