5.5 Pedicle Screw RFQ
What is a 5.5 Pedicle Screw System?
The 5.5 Pedicle Screw System is a posterior spinal fixation system designed for thoracic and lumbar spine stabilization, spinal fusion, fracture fixation, and deformity correction procedures.
The system consists of pedicle screws, spinal rods, locking caps, and compatible surgical instruments, providing reliable mechanical stability and precise spinal alignment control.
Manufactured from medical-grade Ti-6Al-4V titanium alloy, the 5.5 spinal pedicle screw system offers excellent biocompatibility, high fatigue strength, corrosion resistance, and long-term implantation reliability.
It is widely used in orthopedic and neurosurgical applications, including thoracolumbar fixation, posterior lumbar fusion, and complex spinal reconstruction.
What are the main applications of the 5.5 Pedicle Screw System?
The 5.5 spinal fixation system is designed for a wide range of posterior spinal stabilization procedures.
Typical clinical applications include thoracolumbar fracture fixation, degenerative spinal disease treatment, spinal deformity correction, and fusion surgeries.
Thoracolumbar Fracture Fixation
The pedicle screw system provides stable fixation for vertebral fractures, including compression fractures, burst fractures, and traumatic spinal instability.
Its rigid screw-rod construct helps restore spinal stability and maintain postoperative alignment.
Degenerative Spine Treatment
The system can be used for lumbar degenerative disc disease, spinal stenosis, spondylolisthesis, and segmental instability requiring posterior fusion.
The reliable fixation strength supports successful spinal fusion and long-term stability.
Spinal Deformity Correction
The 5.5 pedicle screw system supports correction procedures for scoliosis, kyphosis, and other spinal alignment disorders.
Multiple screw configurations allow surgeons to select suitable fixation strategies according to different anatomical conditions.
What materials are used for the 5.5 Pedicle Screw System?
The standard 5.5 Pedicle Screw System is manufactured from premium Ti-6Al-4V medical titanium alloy.
Titanium alloy provides excellent biocompatibility, high mechanical performance, lightweight properties, and superior corrosion resistance.
The material is widely accepted for orthopedic implant applications due to its long-term safety and durability.
Optional materials and surface treatments can be customized according to customer requirements.
What are the advantages of the 5.5 Spinal Pedicle Screw System?
The 5.5 spinal pedicle screw system offers several advantages for surgeons, distributors, and medical device partners.
Stable Screw-Rod Fixation
The optimized locking mechanism ensures secure connection between pedicle screws and 5.5mm spinal rods.
The stable construct improves resistance against loosening and provides reliable postoperative spinal support.
Multiple Screw Configurations
The system is available with different screw options, including monoaxial pedicle screws, polyaxial pedicle screws, and reduction screws.
These configurations provide surgical flexibility for different spinal fixation requirements.
Precision Manufacturing
Produced through advanced CNC machining technology, each component features accurate dimensions, smooth surface finishing, and consistent mechanical performance.
Strict quality control processes ensure product reliability and compliance with medical implant manufacturing requirements.
What is the difference between monoaxial and polyaxial pedicle screws?
A monoaxial pedicle screw has a fixed screw head structure, providing higher rigidity and stronger axial load transfer.
It is suitable for applications requiring strong stabilization and controlled fixation.
A polyaxial pedicle screw allows multi-directional movement of the screw head, making rod placement easier and improving surgical flexibility.
Both screw types are commonly used in posterior spinal fixation procedures depending on clinical requirements.
