ATLAS 5.5 Reduction Polyaxial Pedicle Screw Insights

What is a Reduction Polyaxial Pedicle Screw?

A reduction polyaxial pedicle screw combines traditional screw anchorage with integrated reduction mechanisms, allowing gradual, controlled repositioning of spinal vertebrae. It is especially valuable in procedures requiring vertebral realignment, such as scoliosis correction, traumatic dislocations, and kyphotic deformities. The "polyaxial" function permits the screw head to pivot in multiple directions, enabling easier rod placement even in complex anatomical structures.

Clinical Applications of ATLAS 5.5 Reduction Polyaxial Pedicle Screw

Spinal deformity corrections (e.g., scoliosis, kyphosis)

Traumatic fractures and dislocations

Revision surgeries requiring vertebral repositioning

Complex thoracolumbar stabilization

Advantages of ATLAS 5.5 Reduction Polyaxial Pedicle Screw

Allows precise, controlled reduction without compromising screw integrity

Reduces surgical time by simplifying rod insertion

Enhances correction of spinal alignment with stable fixation

Supports open and minimally invasive procedures

Break-off tabs ensure low-profile final construct

Biomechanics of ATLAS 5.5 Reduction 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 Reduction Polyaxial Pedicle Screw

Preoperative Planning: Evaluate imaging to select appropriate screw size and trajectory.

Screw Insertion: Place the pedicle screw using a freehand or navigated technique to ensure accurate pedicle entry and trajectory.

Rod Placement and Reduction: Use the reduction tabs to gradually guide the rod into the screw heads, facilitating controlled vertebral realignment.

Locking the Construct: Insert and tighten set screws to lock the rod and screws into a stable construct.

Tab Removal: Break off the reduction tabs cleanly after locking to minimize implant profile.

Final Verification: Use fluoroscopy or X-ray imaging to confirm correct implant positioning and construct stability.

Postoperative Care of ATLAS 5.5 Reduction Polyaxial Pedicle Screw

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

Restrict bending, twisting, and heavy lifting during initial recovery to protect the implant site.

Schedule regular follow-up imaging to monitor fusion progress and hardware integrity.

Manage pain with prescribed analgesics and address any discomfort promptly.

Initiate supervised physical therapy focusing on gradual restoration of mobility and strength.

Vigilantly monitor for signs of infection or complications and report any abnormal symptoms immediately.

Conclusion

The ATLAS 5.5 Reduction Polyaxial Pedicle Screw combines innovative reduction technology with proven polyaxial fixation principles. It provides surgeons with enhanced control during complex spinal deformity and trauma surgeries, improving patient outcomes through precise vertebral realignment and durable implant stability. Manufactured to international quality standards, it supports both open and minimally invasive surgical techniques, making it a versatile and reliable choice in modern spinal care.
