Product Introduction
Core FunctionInterbody Fusion Devices are implantable spinal implants designed to restore intervertebral disc height, stabilize the spinal segment, and provide a structural scaffold for bony fusion. Used in anterior/posterior lumbar and cervical fusion procedures, they treat degenerative disc disease, spinal trauma, tumors, deformities (kyphosis/lordosis/scoliosis), pseudarthrosis, and failed prior fusions, ultimately restoring spinal alignment and long-term biomechanical stability.
Material Options
- PEEK (Polyether Ether Ketone): The primary material, with an elastic modulus closely matching natural bone to minimize stress shielding, excellent radiolucency for post-op fusion monitoring, and superior biocompatibility.
- Titanium Alloy (Ti-6Al-4V ELI): Used for porous or hybrid cages, offering enhanced osseointegration and mechanical strength for high-load segments.
- Composite Materials: PEEK-titanium or PEEK-HA composites, combining the radiolucency of PEEK with the bone-integrating properties of titanium/HA for optimal clinical outcomes.
- Surface Engineering: Porous structures (3D-printed or porous coating) promote bone ingrowth; visibility windows allow intraoperative graft placement monitoring; lordotic profiles reduce intraoperative bending.
Design & System Configuration
The product line includes cervical and lumbar fusion devices, with specialized designs for TLIF (transforaminal) and PLIF (posterior lumbar) approaches:
- Cervical Cages: Compact, low-profile designs for anterior cervical fusion, with self-tapping screws for secure fixation.
- Lumbar Cages (TLIF/PLIF): Anatomically contoured to fit the lumbar intervertebral space, with lordotic angles to restore spinal lordosis; modular sizes and wedge/block geometries to address bone defects.
- Fixation System: Complementary cage fixation screws provide supplementary stability, preventing cage migration and enhancing fusion rates.
Size Specifications
- Cervical Cages: Height 4–8mm, width 12–18mm, length 10–14mm, with incremental sizing to match cervical disc spaces.
- Lumbar Cages (TLIF/PLIF): Height 8–14mm, width 16–26mm, length 22–32mm, with lordotic angles of 5°–15° to restore spinal alignment.
- Fixation Screws: Diameter 2.0–4.0mm, length 6–12mm, self-tapping design for easy intraoperative insertion.
Key Advantages
- Biomechanical Compatibility: PEEK/titanium materials match bone modulus, reducing stress shielding and promoting natural bone fusion.
- Surgical Efficiency: Lordotic design, visibility windows, and self-tapping screws streamline intraoperative handling, shortening operating time.
- Enhanced Fusion: Porous structures and bone-integrating surfaces accelerate osseointegration, lowering pseudarthrosis risk.
- Radiolucency: PEEK cages allow clear post-op X-ray/CT monitoring of fusion progress, critical for clinical follow-up.
- Compliance & Customization: ISO 13485 certified, meeting global orthopedic standards (ASTM F2077, ISO 12394). Full OEM customization available for sizes, materials, and branding, with low MOQ for prototyping and fast lead times for mass production.
