5.5 Polyaxial Pedical Screw : A Comprehensive Guide

The 5.5 polyaxial pedicle screw is a cornerstone in modern spinal fixation systems, designed to provide flexibility, stability, and adaptability for complex spinal conditions. Its advanced design enables precise alignment and rigid stabilization, making it indispensable for orthopedic surgeons treating trauma, deformities, and degenerative diseases. This guide explores the key features, advantages, and clinical applications of the 5.5 polyaxial pedicle screw.

What is 5.5 Polyaxial Pedical Screw？

A 5.5 polyaxial pedicle screw is a spinal implant featuring a multi-directional head, allowing for precise alignment of rods during fixation. The "5.5" denotes its compatibility with 5.5 mm diameter rods, ensuring a secure and robust connection. Constructed from high-grade titanium or cobalt-chromium, the screw provides exceptional durability and biocompatibility. It is commonly used in spinal surgeries for deformity correction, fracture stabilization, and degenerative condition management.

5.5 Polyaxial Pedical Screw Treatment of Fracture Types

Spinal Deformities

Corrects scoliosis, kyphosis, and lordosis with precision and stability.

Traumatic Injuries

Stabilizes fractures and dislocations in the thoracic and lumbar spine.

Degenerative Diseases

Provides support in cases of spondylolisthesis, spinal stenosis, and disc degeneration.

Post-Tumor Resection Reconstruction

 Maintains spinal integrity following vertebral tumor removal.

Complex Fusion Cases

Enhances construct stability in multilevel fusion surgeries.

Risks of 5.5 Polyaxial Pedical Screw Surgery

Infection

Postoperative infections, though rare, may require medical intervention.

Hardware Loosening

Improper placement or excessive biomechanical stress can compromise fixation.

Adjacent Segment Disease

Altered spinal mechanics may lead to degeneration in neighboring vertebral levels.

Implant Failure

Rare cases of screw or rod failure may necessitate revision surgery.

Soft Tissue Irritation

Occasionally, hardware prominence can cause discomfort in certain patients.

5.5 Polyaxial Pedical Screw Future Marke

Technological Innovations

Advancements in materials, thread design, and surgical techniques enhance performance.

Increasing Spinal Surgeries

Rising incidences of spinal deformities, trauma, and degenerative conditions boost demand.

Global Adoption of Minimally Invasive Surgery (MIS)

Compatibility with MIS techniques broadens market reach.

Aging Population

Higher prevalence of spinal disorders among the elderly contributes to market expansion.

Emerging Markets

Improved healthcare infrastructure in developing regions supports adoption.

Summary

The 5.5 polyaxial pedicle screw is a vital tool in modern spinal surgery, offering unmatched flexibility, stability, and adaptability. Its advanced design and versatile applications make it an essential component in treating complex spinal conditions.
