Polyaxial Pedicle Screw

The Polyaxial Pedicle Screw is a premier component of modern spinal fixation systems, engineered to deliver exceptional vertebral anchorage and flexible rod alignment during spinal fusion procedures. Featuring a multi-directional trailing head, this system grants orthopedic surgeons maximum intraoperative flexibility, facilitating easier rod placement and reduction in complex spinal reconstructions. Manufactured from premium implant-grade titanium alloy and processed through a state-of-the-art quality management infrastructure, this system provides highly dependable, regulatory-compliant solutions for international orthopedic distributors, hospital procurement networks, and medical device partners.

The Polyaxial Pedicle Screw System is a comprehensive posterior fixation assembly meticulously architected to accommodate anatomical variations and minimize stress concentration on the bone-screw interface. The integrated system consists of the following synchronized elements:

Polyaxial Pedicle Screws: The core anchoring mechanism featuring a 40-degree omnidirectional ball-and-socket head joint, allowing extensive angular adjustment to eliminate aggressive intraoperative rod contouring.

Spinal Rods: Available in straight and pre-contoured formats to contour seamlessly to patient anatomy and maintain rigid long-term spinal alignment.

Low-Profile Locking Caps: Incorporates a modified buttress thread design to eliminate cross-threading and prevent head splay during high-torque final tightening.

Cross Connectors: Transverse stabilization links that significantly enhance the rotational and torsional rigidity of the entire construct.

Ergonomic Surgical Instrumentation: A dedicated, fully integrated kit including rigid star-drive screwdrivers, counter-torque wrenches, and depth gauges optimized for streamlined surgical handling.

Dual-Thread Geometry: The screw shaft features a specialized conical core and dual-lead pitch that doubles the insertion advancement speed while maximizing bone purchase in both cortical and cancellous bone structures.

Ultra-Pure Biocompatible Material: Fabricated strictly from medical-grade titanium alloy, offering optimal fatigue strength, excellent corrosion resistance, and superb artifact-free performance under post-operative MRI and CT imaging.

Slip-Free Torque Transmission: Precision-machined hexalobular drive interfaces ensure perfect tool engagement, minimizing the risk of driver slippage or head stripping during high-load insertion.

Versatile Anatomical Sizing: Available in an extensive matrix of diameters and lengths to provide custom-fit solutions for varying patient profiles and complex structural reconstructions.

This system is clinically indicated for a wide spectrum of spinal pathologies requiring rigid stabilization through posterior thoracic, lumbar, or sacral intervention:

To meet the rigorous quality expectations and regulatory compliance demanded by international healthcare buyers, the production infrastructure is built upon uncompromised precision, total predictability, and structural validation:

Advanced CNC Precision Machining: Every screw is manufactured utilizing high-precision Swiss-type CNC lathe machines, ensuring dimensional tolerances are kept strictly within micron levels.

Certified Cleanroom Processing: Cleaning, final inspection, and primary medical-grade packaging are executed entirely inside Class 100,000 (ISO Class 7) cleanrooms to guarantee strict bioburden control.

Rigorous Biomechanical Testing: All implant designs undergo exhaustive mechanical evaluations, including static and fatigue testing under axial, torsional, and bending loads according to international ASTM F1717 standards.

Full Batch Traceability: Raw materials undergo strict spectroscopic validation upon receipt. Every production batch is backed by material test reports, heat treatment documentation, and comprehensive quality certificates.

Scalable Production Capacities: Equipped with robust manufacturing capacity to support scalable contract manufacturing, flexible private label requirements, and reliable lead times for large-scale international procurement orders.
