Advanced Thoracic and Lumbar Pedicle Screw Solutions for Spinal Stability
Pedicle screw fixation is a fundamental technique in contemporary spinal surgery, especially for rebuilding the thoracic and lumbar spine. As a critical orthopedic implant, the pedicle screw system provides rigid posterior stabilization by anchoring securely into the pedicle of vertebrae, allowing surgeons to correct deformities, restore alignment, and promote spinal fusion.
ATOM’s Thoracic and Lumbar Pedicle Screw System is designed to support a wide range of spinal procedures, offering reliable fixation through a complete rod-screw-system that integrates precision engineering, biomechanical strength, and surgical versatility.
Understanding the Vertebral Pedicle and Pedicle Screws
The vertebral pedicle is a short, strong bony structure connecting the vertebral body to the posterior elements. Each pedicle of the vertebrae forms a critical load-bearing pathway, making it the ideal anchor point for pedicular screws.Pedicle screws are specialized spinal screws inserted through the pedicles of the spine into the vertebral body. Once implanted, they are connected using spinal fusion rods and screws, creating a rigid construct that stabilizes the spine during healing.
This technique is widely used in:
· Thoracic vertebrae pedicle fixation
· Lumbar spine pedicle fixation
· Posterior screw fixation for spinal fusion
Types of Pedicle Screws Used in Thoracic and Lumbar Surgery
Polyaxial Pedicle Screw
A Polyaxial Pedicle Screw features a mobile screw head, allowing angular adjustment between the screw and the rod. This flexibility makes it easier to place and align rods, especially in complicated reconstructions of the thoracic and lumbar regions.
Monoaxial Pedicle Screw
A Monoaxial Pedicle Screw has a fixed head, offering higher rigidity and stronger corrective force. It is often used in fracture reduction or deformity correction surgeries that require precise spinal alignment.
Both designs play crucial roles in contemporary pedicular screw fixation systems, with ATOM providing a comprehensive portfolio to support various surgical techniques.
Percutaneous Pedicle Screw Fixation: Minimally Invasive Advancement
Percutaneous pedicle screw fixation has become increasingly popular due to its minimally invasive nature. This technique allows percutaneous screw fixation through small incisions, reducing muscle damage, blood loss, and postoperative pain.
ATOM's system supports percutaneous pedicle screw fixation for thoracic and lumbar spine procedures, making it suitable for trauma cases, degenerative diseases, and minimally invasive spinal fusion.
Clinical Applications in Thoracic and Lumbar Spine
Pedicle screw systems are widely used in:
· Lumbar fusion with rods and screws
· Rods and screws in lower back stabilization
· Posterior fixation of thoracic spine fractures
· Correction of scoliosis and spinal deformities
· Degenerative lumbar spine conditions
· Fixation involving the pedicle of L5 and pedicle lumbar vertebrae
By anchoring into the lumbar vertebrae pedicle and pedicles of lumbar spine, pedicle screws provide superior three-column spinal stability.
Titanium Rods and Screws in Back Surgery
ATOM's thoracic and lumbar systems utilize titanium rods and screws in back surgery, offering:
· Excellent biocompatibility
· High fatigue strength
· Corrosion resistance
· MRI compatibility
Titanium medical screws ensure long-term stability and safety, even in multilevel spinal constructs.
Rod-Screw System Design and Biomechanical Advantages
A complete rod-screw-system consists of:
· Pedicle screws
· Spinal rods
· Set screws and connectors
This configuration enables controlled spinal correction while maintaining construct rigidity. Proper engagement within the pedicle of thoracic vertebrae and pedicle lumbar spine allows effective load sharing and fusion support.
Treatment for Loose Pedicle Screws
In revision surgery, treatment for loose pedicle screws may involve:
· Larger diameter pedicular screws
· Cement augmentation
· Revised screw trajectory within the vertebral pedicle
· Reinforced posterior screw fixation
High-quality implant design and precise surgical technique are key to minimizing loosening risk.
Anatomical Considerations: Mamillary Process and Lumbar Pedicle Entry
In lumbar spine surgery, anatomical landmarks such as the mamillary process are crucial for accurate pedicle screw insertion. Correct identification of the spinal pedicle and optimal trajectory reduces complications and improves fixation strength.
