The ATLAS 5.5 Crosslink II is a bilateral clamp-type cross connector designed to be incorporated into posterior thoracolumbar spinal constructs to resist axial rotation, lateral bending, and shear. It comprises high-grade Ti‑6Al‑4V titanium alloy and is engineered for use with paired 5.5 mm rods, typically at the distal, mid, or proximal levels to augment overall construct stability.

Product Description
Titanium Alloy Construction: Offers excellent biocompatibility, fatigue resistance, and corrosion durability.
Low‑Profile Design: Minimizes implant prominence and soft tissue irritation.
Dual Clamp System: Securely grips both 5.5 mm rods with precision torque-limited screws, enhancing ease of assembly.
Improved Construct Rigidity: Enhances resistance to torsional and lateral bending forces by linking both rods.
Versatile Positioning: Usable at different levels (proximal, mid, distal) depending on surgical plan.
Simplified Instrumentation: Compatible with standard ATLAS screwdrivers and torque tools.
The ATLAS 5.5 Crosslink II is indicated for spinal fusion constructs requiring enhanced stability, including:
Long-segment thoracolumbar deformity correction
Multilevel fusion in scoliosis or kyphosis
Revision surgeries with compromised posterior tension band
Post-traumatic spinal instability
Spinal tumor or infection requiring stronger fixation support

It is an interconnect device used to link two parallel 5.5 mm posterior spinal rods, enhancing the rigidity and multidirectional stability of thoracolumbar constructs. Typically placed at strategic levels, crosslinks reduce micromotion and help prevent implant failure.
The ATLAS 5.5 Crosslink II is indicated for use in:
Deformity Correction: Supports scoliotic or kyphotic corrections across multiple segments.
Trauma Stabilization: Adds strength in acute vertebral fractures spanning more than two levels.
Spinal Fusion: Useful in long fusions where torsional forces are significant.
Revision Surgery: Enhances construct stability when prior implants need reinforcement.
Tumor/Inflammation Cases: Adds biomechanical support where bone quality is compromised.
Enhanced Torsional Resistance: By rigidly linking bilateral rods.
Increased Bending Resistance: Crosslink reinforces against lateral and shear forces.
Ease of Use: Symmetric clamps and torque-limited screws simplify placement.
Reduced Hardware Loosening: Rigidity mitigates stress on set screws and rods.
Low Soft-Tissue Profile: Less hardware prominence reduces postoperative irritation.
Crosslinks significantly increase rotational stiffness by creating a triangulated structure, reducing relative motion between rods. Biomechanical tests show reductions in hardware deflection and micro-motion across constructs, improving fusion success in long spinal segments.
Placement: After rods are seated and set screws tightened, choose crosslink location.
Clamping: Place rods into the clamp slots; tighten screws sequentially with torque-limited drivers.
Verification: Confirm symmetrical alignment and confirm under fluoroscopy.
Integration: Compatible with ATLAS towers, hooks, and crosslink spacers when needed.
Following implantation, proper postoperative care is essential to ensure healing and prevent complications:
Imaging: Routine postoperative X-rays or CT to confirm hardware integrity.
Activity Protocols: Standard postoperative spinal care applies—avoid high torque stress for initial 6–12 weeks.
Follow-up: Monitor for implant loosening or signs of non-union; crosslink presence typically reduces such complications.
The ATLAS 5.5 Crosslink II is an essential component for enhancing spinal construct stability—especially in multilevel, deformity, or revision spinal surgery. It integrates seamlessly with ATLAS implant systems, offering outstanding torque resistance and fatigue strength while maintaining low-profile design. Certified under CE and ISO standards, it ensures safety, surgical efficiency, and long-term biomechanical reliability.
By linking bilateral rods, a crosslink forms a triangulated structure that significantly increases resistance to torsion and lateral bending—improving long-term construct stability.
Recommended in long posterior constructs (3+ levels), especially in deformity correction, trauma cases, revisions, or low bone quality scenarios to minimize implant load.
Lengths available include 60mm, 70mm, and 80mm—matching typical rod spacing in thoracolumbar constructs.
It is specifically designed for ATLAS 5.5 mm rods. Use with other systems depends on matching rod diameters and clamp geometry—compatibility must be verified.
Hardware removal or revision follows standard protocols—releasing set screws with torque-limiting drivers allows safe removal and potential repositioning.
