Zero-profile Cervical Fusion PEEK Cage with Locking Screws

Zero-Profile Cervical Fusion PEEK Cage with Locking Screws
Precision Engineering for Optimal Cervical Fusion

Product Overview:

Key Specifications:

• Materials: Bioinert PEEK polymer spacer; Titanium alloy (Ti-6Al-4V) locking screws.
• Sizes: Multiple footprints (e.g., 14–18mm) and heights (e.g., 4–7mm) for C2–T1 anatomy.
• Design: Monobloc spacer with pre-angled screw trajectories; Self-distracting leading edge; Self-locking screw mechanism.

Intended Use:

• Degenerative Disc Disease (DDD)
• Cervical Spondylosis
• Herniated Nucleus Pulposus
• Spinal Stenosis
• Deformity/Instability Correction

Clinical Advantages:

1. Zero-Profile Design: Minimizes implant prominence and reduces dysphagia risk.
2. All-in-One Solution: Combines fusion cage and fixation without auxiliary plating.
3. PEEK Biomaterial: Modulus elasticity similar to bone (reduces stress-shielding); MRI/CT compatible.
4. Locking Screw Technology: Screws lock into the spacer, preventing back-out and offering immediate stability.
5. Simplified Technique: Reduced operative steps and instrumentation vs. plate-cage systems.
6. Optimized Fusion: Graft chamber permits autologous/allograft bone packing.

Contraindications:

• Active systemic infection or localized infection at surgical site
• Osteoporosis, metabolic bone disease, or inadequate bone stock
• Sensitivity to implant materials (PEEK/titanium alloy)
• Multi-level fusion requirements
• Pregnancy or pediatric patients
• Morbid obesity (BMI >40) or conditions compromising wound healing
