ATLAS 5.5 Polyaxial Pedicle Screw Insights

What is a Polyaxial Pedicle Screw?

A polyaxial pedicle screw is a type of spinal implant used in posterior spinal fusion surgeries. Unlike monoaxial screws, polyaxial screws have a swivel head that allows movement in multiple directions, typically ±20–30°. This flexibility helps surgeons align the connecting rods more easily, especially in complex anatomical conditions or spinal deformities. It improves construct stability while reducing stress at the bone-screw interface during correction maneuvers.

Applications of ATLAS 5.5 Polyaxial Pedicle Screw

The ATLAS 5.5 Polyaxial Pedicle Screw is indicated for use in:

Degenerative disc disease

Spondylolisthesis

Spinal deformities such as scoliosis and kyphosis

Fracture stabilization

Tumor resection and spinal fusion procedures

Advantages of ATLAS 5.5 Polyaxial Pedicle Screw

Polyaxial Design: Allows ±20–30° of angulation for easier rod alignment and optimal screw placement

Robust Fixation: Enhanced thread geometry ensures secure grip in both cortical and cancellous bone

Rod Compatibility: Seamlessly integrates with 5.5 mm spinal rods for stable construct formation

Ease of Use: Reduced instrumentation steps improve OR efficiency and surgical workflow

Corrosion-Resistant Material: Titanium alloy ensures durability and long-term implant integrity

Biomechanics of ATLAS 5.5 Polyaxial Pedicle Screw

The design features a ball‑and‑socket polyaxial interface to accommodate rod contouring, while the dual‑lead threads reduce insertion torque and distribute compression effectively. The tapered tip supports safe pedicle entry and strong bicortical fixation.

Surgical Technique of ATLAS 5.5 Polyaxial Pedicle Screw

Fracture Reduction: Bone fragments are aligned and stabilized using clamps or temporary fixation.

Plate Placement: The implant is contoured to match the bone surface if needed.

Screw Insertion: Combination of cortical and locking screws is used based on the surgeon’s plan.

Fixation Finalization: Locking screws are secured into the threaded portion to create angular stability.

Postoperative Care of ATLAS 5.5 Polyaxial Pedicle Screw

Following implantation, proper postoperative care is essential to ensure healing and prevent complications:

Activity Restriction: Patients should avoid bending, twisting, or lifting heavy objects during early recovery.

Physical Therapy: A supervised rehabilitation plan is recommended to restore mobility and muscle strength.

Follow-up Imaging: Regular X-rays or CT scans may be required to monitor fusion progress and implant positioning.

Infection Monitoring: Surgical site should be observed for any signs of infection such as redness, swelling, or discharge.

Medication Compliance: Pain management and prescribed medications must be taken as directed by the physician.

Conclusion

The ATLAS 5.5 Polyaxial Pedicle Screw offers exceptional stability, alignment flexibility, and surgical efficiency for complex spine procedures. Supported by strong biomechanical performance and certified quality standards, it is a dependable choice for modern spinal fixation needs.
