The ATLAS 5.5mm Rod is a straight or pre-contoured metallic rod used in spinal surgery to connect multiple pedicle screws, stabilizing the spine and facilitating spinal fusion. It acts as a load-sharing device, maintaining proper spinal alignment while bone fusion occurs. Available in various lengths and customizable shapes, this rod is used primarily in posterior thoracolumbar procedures for treating spinal instability, deformities, and trauma.
The ATLAS 5.5mm Rod is suitable for a wide range of posterior spinal procedures, including:
Degenerative disc disease
Scoliosis and kyphosis deformity correction
Traumatic fractures and dislocations
Spondylolisthesis
Spinal tumor resection requiring stabilization
Revision surgeries for failed spinal implants
Its compatibility with ATLAS screws makes it a universal component for various complex and routine spinal constructs.
Biocompatibility: Made from titanium alloy (Ti-6Al-4V), known for its excellent tissue compatibility and corrosion resistance.
Flexibility: Can be contoured intraoperatively to adapt to patient anatomy without significant loss of mechanical strength.
Fatigue Resistance: Designed to endure cyclic loading over time, reducing risk of implant failure.
Radiolucency in Imaging: Titanium allows clearer postoperative imaging for follow-up evaluations.
Compatible System Design: Fully integrated with ATLAS pedicle screws and reduction tools, promoting surgical efficiency and procedural flexibility.
Multiple Lengths Available: To meet different surgical and anatomical needs, rods come in a variety of lengths, typically ranging from 30mm to 500mm.
The biomechanical strength of the ATLAS 5.5mm Rod plays a crucial role in achieving spinal stability postoperatively. Its 5.5mm diameter provides an ideal balance between rigidity and flexibility:
Rigidity: Ensures structural integrity of the spinal construct by resisting deformation under compressive, bending, and torsional loads.
Elastic Modulus Matching: Titanium's modulus is closer to that of bone compared to stainless steel, which reduces stress shielding and supports long-term spinal fusion.
Fatigue Strength: The rod maintains its integrity under repeated load cycles typical of daily motion and spinal load bearing.
These characteristics make the rod especially effective in load-sharing constructs and multilevel stabilization.
The ATLAS 5.5mm Rod is designed to streamline the rod placement step in posterior thoracolumbar surgeries:
Preparation: After inserting pedicle screws, the surgeon selects a rod of appropriate length.
Contouring: If necessary, the rod is bent using rod benders to fit the patient’s spinal curvature.
Placement: The contoured rod is seated into the screw tulips. Extended tabs or tower systems may assist in reduction cases.
Fixation: Set screws are then applied to secure the rod in place, typically using a torque-limiting driver for consistency.
Verification: Final alignment and construct rigidity are verified under fluoroscopy before closure.
The rod’s smooth surface and mechanical properties allow secure handling and reliable seating into the screw heads.
Proper postoperative care following implantation of the ATLAS 5.5mm Rod is essential for optimal outcomes:
Monitoring: Radiographic evaluation is recommended at regular intervals to assess fusion progress and construct integrity.
Rehabilitation: Patients typically undergo a customized rehabilitation program to promote mobility while protecting the fusion site.
Activity Restrictions: Heavy lifting and high-impact activities are restricted during the initial recovery phase (6–12 weeks).
Infection Prevention: Wound care and prophylactic antibiotics are important in minimizing postoperative complications.
Implant Longevity: Most rods remain in the body permanently unless revision surgery is needed.
Patient compliance with follow-up care and activity guidelines significantly affects the long-term success of spinal fusion.
The ATLAS 5.5mm Rod stands as a trusted, high-performance solution for posterior spinal fixation. Designed for compatibility, biomechanical stability, and ease of use, it is indispensable in modern spine surgery. Whether used in trauma stabilization or deformity correction, its titanium construction, fatigue resistance, and intraoperative flexibility deliver consistent results. As a core part of the ATLAS system, it complements a wide range of pedicle screws and surgical techniques—empowering surgeons to perform complex spinal corrections with confidence.
They are commonly used in spinal fusion surgeries, deformity correction, and trauma stabilization from T1 to L5 vertebrae.
Both options are available. Straight rods can be manually contoured in surgery, while pre-bent rods save time during complex curvature correction.
Although optimized for ATLAS screws, it may be mechanically compatible with other 5.5mm systems—but always verify with your surgical team or manufacturer.
It offers sufficient rigidity for multilevel constructs without over-stiffening, making it ideal for both short and long segment procedures.
Typically used for adults, though certain cases in adolescents may warrant its use under professional discretion, especially in deformity correction.
