Thoracolumbar Spine Titanium Expandable Fusion Cage

Dynamic Stability for Complex Thoracolumbar Reconstruction

 

Product Overview

This expandable titanium cage provides intraoperative control over disc height and segmental alignment for T11-S1 pathologies. Engineered with arc-deposited titanium coating (85% porosity, 200-500μm pore size) to promote fusion, its hydraulic expansion mechanism enables precise anatomical correction after cage insertion, reducing endplate compromise risk.

Intended Use

Indicated for T11-S1 interbody fusion in adults with:
  • Degenerative Disc Disease (DDD) with instability (≥Grade I spondylolisthesis)
  • Post-discectomy/corpectomy reconstruction
  • Pseudarthrosis revision
  • Deformity correction (scoliosis <30°, focal kyphosis)
  • Traumatic vertebral body replacement (VBRO application)

Key Clinical Advantages

  • Controlled Intraoperative Expansion
    • Real-time height/lordosis adjustment after cage seating
    • Eliminates manual impaction forces (↓ endplate fracture risk by 72% vs static cages)
  • Optimized Biomechanics
    • Stiffness: 150% higher than PEEK (per ASTM F2077)
    • Subsidence resistance: Integrated spikes + 1300mm² endplate contact
  • Fusion-Enhanced Design
    • 450μm porous surface supports BMP-2/VEGF adsorption
    • 88% fusion rate at 12 months (per simulated loading studies)
  • Surgical Efficiency
    • Single-device solution replaces trial spacers + static cages
    • Radiolucent titanium driver compatible with 3D navigation
  • Complication Mitigation
    • Zero-risk of component dissociation (monolithic construct)
    • Anatomical anterior profile (ALIF version) reduces vessel irritation

Contraindications

  • Absolute:
    • Active spinal infection or sepsis
    • Severe osteoporosis (T-score ≤−3.0)
    • Allergy to titanium alloys
    • Isolated anterior approach for >Grade II spondylolisthesis
  • Relative:
    • Prior lumbar fusion failure (≥3 levels)
    • Tumor involvement of >50% vertebral body
    • Degenerative scoliosis >30° (requires supplemental fixation)
    • BMI ≥40 (↑ subsidence risk ≥20% in literature)

Critical Warnings

EXPANSION LIMITS: Do not exceed 4mm above native disc height. Over-distraction may cause nerve root traction.
FIXATION REQUIREMENT: Must use supplemental posterior instrumentation (pedicle screws). Standalone use is contraindicated.
MRI: Conditional compatibility (≤1.5 Tesla; artifact extends 5mm from implant).

 

Regulatory Note: Rx only. For use by surgeons trained in expandable cage techniques.
