## Introduction
Spinal deformities such as scoliosis and kyphosis require robust mechanical stabilization to achieve and maintain correction. The **Pedicle Screw System** has become the cornerstone of these procedures, providing three-column fixation that allows for powerful corrective forces.
## The Biomechanics of Three-Column Fixation
Pedicle screws penetrate the anterior, middle, and posterior columns of the vertebral body. This provides superior pull-out strength compared to legacy hook or wire systems.
* **Segmental Control:** Allows the surgeon to apply force at each level of the deformity.
* **Derotation:** Specialized reduction screws enable the correction of the rotational component of scoliosis.
* **Load Sharing:** Distributes the physiological load across multiple segments, reducing the risk of construct failure.
## Engineering Excellence in Pedicle Screws
Ortholyx pedicle screws are manufactured from **Ti6Al4V-ELI**, providing high fatigue strength and biocompatibility.
1. **Dual-Lead Threads:** Allow for rapid insertion without sacrificing bone grip.
2. **Polyaxial Head Flexibility:** Simplifies rod placement in complex curvatures.
3. **Low Profile Design:** Reduces soft tissue irritation and hardware prominence.
## Conclusion
Modern pedicle screw systems are precision tools that transform the lives of deformity patients. By combining mechanical strength with surgical flexibility, Ortholyx supports surgeons in achieving optimal spinal alignment.
