Spinal surgery has evolved significantly over the last few decades, driven by breakthroughs in implant design, surgical technology, and biomechanical understanding. Among the most essential elements used in spine stabilization procedures are spinal screws—precisely engineered orthopedic implants that anchor into the vertebrae to maintain alignment, support fusion, and correct deformities.
At Atlas Surgical, we manufacture high-precision spinal screws trusted by surgeons worldwide for their accuracy, strength, and reliability in complex spine procedures. This comprehensive guide explores everything you need to know about spinal screws—types, applications, benefits, and their growing role in modern spine surgery.
Spinal screws are specialized implants designed to stabilize and support the vertebral column during fusion or corrective surgeries. Inserted into the pedicles or vertebral bodies, they act as anchor points to hold rods, plates, or connectors that realign the spine or immobilize specific segments for healing.
The ideal spinal screw must offer:
Atlas Surgical spinal screws are manufactured using premium Titanium and Stainless Steel, ensuring durability, biocompatibility, and mechanical stability for both short-term and long-term spinal correction.
A spinal screw is composed of several engineered components:
The screw head connects with rods or connectors, accommodating various instruments during surgery. Common head types include polyaxial, monoaxial, and uniaxial designs.
The shaft diameter and thread design determine how firmly the screw grips the vertebra.
These provide purchase in the bone and vary depending on:
