The Posterior Cervical Screw System is a specialized high-precision spinal internal fixation implant designed for posterior cervical spine stabilization and reconstructive surgery. Developed based on human cervical anatomical characteristics and spinal biomechanical principles, this screw system provides rigid three-dimensional fixation for cervical degenerative diseases, traumatic fractures, spinal instability and deformity correction. As a core implant for posterior cervical minimally invasive surgery, it is widely adopted in spine surgery centers to achieve safe and reliable cervical spine reconstruction.
Different from conventional spinal fixation devices, the posterior cervical screw system features individualized anatomical design with optimized screw diameter, thread pitch and screw length. It is specially tailored for the small bone volume and complex neural vascular distribution of the cervical vertebrae. The precision thread structure enhances bone holding force, effectively preventing screw loosening and withdrawal, especially suitable for patients with osteoporosis and poor bone quality. Combined with matching connecting rods and locking structures, it forms a stable posterior fixation frame to restore cervical spinal mechanical balance.
This system supports multi-point fixation across cervical segments, allowing flexible segmental fixation and correction according to different lesion ranges. The multi-angle adjustable design enables accurate screw placement along the optimal bony trajectory, effectively avoiding damage to the vertebral artery, spinal cord and nerve roots. It minimizes intraoperative bone resection and soft tissue dissection, reduces surgical trauma, and preserves more physiological motion functions of the cervical spine compared with traditional extensive fusion systems.
Clinically, the Posterior Cervical Screw System is indicated for cervical spine fractures and dislocations, cervical spondylotic myelopathy, posterior ligament complex injury, cervical spinal instability, and mild cervical deformity correction. The rigid fixation structure maintains long-term spinal stability, creates favorable conditions for bone graft fusion, and effectively reduces postoperative complications such as fusion failure and spinal malalignment. It also allows early postoperative functional training to accelerate patient rehabilitation.
Manufactured from medical-grade titanium alloy, the system delivers outstanding biocompatibility, high fatigue resistance and reliable mechanical strength. The smooth polished surface reduces soft tissue irritation and intraoperative friction. Its standardized specifications are highly compatible with supporting spinal surgical instruments, ensuring convenient implantation and precise locking. With superior safety, stability and clinical practicability, the Posterior Cervical Screw System has become an essential implant for modern posterior cervical spine reconstructive surgery.
