Percutaneous Pedicle Screw

Product Introduction

The Percutaneous Pedicle Screw Internal Fixation System is designed for minimally invasive spinal stabilization procedures, enabling accurate placement of pedicle screws through small skin incisions. The system combines advanced percutaneous instrumentation with reliable screw-rod fixation technology to provide stable spinal support while reducing muscle damage, blood loss, and postoperative pain.

Featuring coaxial and polyaxial variable pitch pedicle screws, the system allows flexible intraoperative adjustment, improved surgical efficiency, and enhanced fixation performance. It is widely used for thoracolumbar fractures, spinal instability, degenerative spinal disorders, and other conditions requiring posterior spinal fixation.

Indications

The Percutaneous Pedicle Screw Internal Fixation System is suitable for:

• Spinal stenosis
  Provides stabilization after decompression procedures to maintain spinal alignment.

• Spondylolisthesis
  Helps restore and maintain vertebral stability through posterior fixation.

• Thoracolumbar fractures
  Suitable for stable and unstable compression fractures, burst fractures, and traumatic spinal instability requiring fixation.

• Degenerative spinal instability
  Provides mechanical support for degenerative conditions requiring spinal fusion.

• Spinal deformity correction
  Supports segmental fixation and correction procedures when clinically indicated.

Contraindications

The system should not be used in patients with:

• Active spinal infection

• Severe osteoporosis with insufficient bone quality for screw fixation

• Severe systemic conditions affecting bone healing

Percutaneous Pedicle Screw FAQ

What is a Percutaneous Pedicle Screw System?

A Percutaneous Pedicle Screw System is a minimally invasive spinal fixation system designed to stabilize the spine through small skin incisions.
It allows surgeons to insert pedicle screws and connecting rods with reduced disruption to paraspinal muscles and soft tissues compared with traditional open spinal surgery.
The system is commonly used for thoracolumbar stabilization, spinal fusion procedures, and minimally invasive spine surgery (MISS).

What are the main applications of Percutaneous Pedicle Screws?

Percutaneous Pedicle Screws are widely used for posterior spinal fixation in various spinal conditions, including thoracolumbar fractures, spinal instability, degenerative spinal disorders, spondylolisthesis, and spinal stenosis.
They provide reliable vertebral stabilization and support spinal fusion by maintaining proper alignment and mechanical stability.

What spinal conditions can be treated with a Percutaneous Pedicle Screw System?

Can Percutaneous Pedicle Screws be used for spinal fractures?

Yes, the system is frequently used for thoracolumbar fractures, including compression fractures, burst fractures, and traumatic spinal instability requiring posterior fixation.
The minimally invasive approach helps reduce surgical trauma while providing effective stabilization for fracture healing.

Are Percutaneous Pedicle Screws suitable for degenerative spine diseases?

Yes, Percutaneous Pedicle Screw Fixation can be applied in degenerative spinal conditions such as lumbar instability, spondylolisthesis, and spinal stenosis when stabilization and fusion are clinically required.
The system helps restore spinal stability while minimizing soft tissue damage.

What are the advantages of Percutaneous Pedicle Screw Fixation compared with traditional open surgery?

The main advantages include smaller incisions, reduced muscle damage, less intraoperative blood loss, decreased postoperative pain, and faster patient recovery.
Because the procedure preserves more paraspinal muscle structures, patients may experience earlier mobilization and improved postoperative rehabilitation.

How does a Percutaneous Pedicle Screw reduce surgical trauma?

The system uses specialized minimally invasive spinal instruments that allow screw placement through approximately 1.5 cm incisions.
This technique avoids extensive muscle stripping and reduces damage to surrounding tissues, helping lower postoperative discomfort and shorten recovery time.

What types of Percutaneous Pedicle Screws are available?

Percutaneous Pedicle Screw Systems are available in different configurations to meet various surgical requirements, including coaxial variable pitch pedicle screws and polyaxial variable pitch pedicle screws.
Different screw designs provide flexibility in insertion angle adjustment, fixation strength, and intraoperative rod connection.

What is the difference between coaxial and polyaxial Percutaneous Pedicle Screws?

What are coaxial variable pitch pedicle screws?

Coaxial variable pitch pedicle screws provide a more controlled screw trajectory and are designed for applications requiring enhanced insertion stability and precise alignment.
The variable pitch thread design improves bone engagement and helps achieve strong fixation performance.

What are polyaxial variable pitch pedicle screws?

Polyaxial pedicle screws allow multi-directional head movement, providing greater flexibility during rod placement and spinal alignment correction.
They are especially useful in complex spinal fixation procedures where intraoperative adjustment is required.

What materials are used for Percutaneous Pedicle Screws?

Percutaneous Pedicle Screws are typically manufactured from medical-grade titanium alloy due to its excellent biocompatibility, corrosion resistance, and mechanical strength.
Titanium alloy materials provide reliable long-term implant performance and compatibility with spinal fusion procedures.

What sizes are available for Percutaneous Pedicle Screws?

The available sizes depend on the specific implant design and anatomical requirements.
Common diameter options include 5.5 mm, 6.0 mm, 6.5 mm, and 7.0 mm, with screw lengths generally ranging from 30 mm to 55 mm.
Customized sizes and specifications can also be provided according to surgeon requirements and OEM/ODM projects.

How is the Percutaneous Pedicle Screw implanted?

The procedure usually involves inserting a guide wire through the pedicle, preparing the screw pathway, and placing the cannulated pedicle screw under fluoroscopic guidance.
After screw placement, connecting rods are inserted to complete posterior spinal fixation.
The minimally invasive technique helps improve surgical accuracy while reducing soft tissue disruption.

Is fluoroscopy or navigation required for Percutaneous Pedicle Screw placement?

Percutaneous Pedicle Screw implantation is commonly performed with imaging assistance such as C-arm fluoroscopy or navigation systems.
These technologies help surgeons achieve accurate pedicle screw positioning and improve procedural safety during minimally invasive spine surgery.

What instruments are required for Percutaneous Pedicle Screw surgery?

A complete Percutaneous Pedicle Screw Instrument Set usually includes guide wires, cannulated awls, pedicle probes, taps, screwdrivers, screw extenders, rod inserters, reduction instruments, and torque limiting handles.
Specialized minimally invasive spinal instruments improve surgical efficiency and implant accuracy.

What are the contraindications of Percutaneous Pedicle Screw Fixation?

Contraindications may include active spinal infection, severe osteoporosis with insufficient fixation strength, severe bone quality problems, or conditions that prevent safe implant placement.
Patient evaluation should be performed by qualified surgeons before selecting the appropriate fixation method.

How long does recovery take after Percutaneous Pedicle Screw surgery?

Recovery time varies depending on the patient's condition, surgical level, and fusion requirements.
Compared with traditional open spinal fixation, minimally invasive pedicle screw fixation may reduce soft tissue injury and allow earlier postoperative mobilization.

Can Percutaneous Pedicle Screws be customized for different markets?

Yes, Percutaneous Pedicle Screw Systems can be customized according to different surgical requirements, including screw diameter, length, thread design, instrumentation, and packaging solutions.
