Product Overview
The Cervical Titanium Mesh is a vertebral body replacement system designed for spinal reconstruction following corpectomy. Manufactured from medical-grade TA3G pure titanium, this load-sharing implant provides immediate structural support and promotes bony fusion through its open lattice architecture, which allows bone graft ingrowth from all directions. The cylindrical mesh can be intraoperatively trimmed to match patient-specific anatomy and is suitable for cervical, thoracic, and lumbar segments. When paired with toothed anatomical endcaps, the system effectively resists subsidence and enhances initial stability—delivering reliable clinical outcomes for anterior column reconstruction.
Indications for Use
The Cervical Titanium Mesh System is indicated for the following clinical scenarios:
Vertebral body replacement following corpectomy for tumor resection, trauma, or infectious disease affecting the cervical spine.
Spinal fusion support in degenerative conditions requiring anterior column reconstruction with immediate structural stability.
Post-traumatic burst fractures where the vertebral body is irreparably damaged and requires excision and reconstruction.
Spinal deformity correction where interbody height restoration and sagittal alignment are critical.
Revision surgery for failed previous fusion constructs or pseudoarthrosis requiring new graft containment.
Multi-level corpectomy procedures (up to two or more levels) where rigid anterior column support is mandatory.
Osteoporotic fractures where the mesh provides enhanced endplate purchase and reduces the risk of implant subsidence.
Key Advantages
Advantage | Clinical Benefit |
|---|---|
Multidirectional Bone Ingrowth | The network-shaped mesh structure allows cancellous bone graft to grow through all surfaces, creating a circumferential biological fusion that enhances long-term stability. |
Excellent Mechanical Strength | Manufactured from high-purity TA3G titanium, the mesh withstands physiological axial loads while maintaining structural integrity during the fusion maturation period. |
Intraoperative Customization | Can be easily trimmed to the exact length required during surgery, accommodating variable corpectomy defects and patient-specific anatomy without requiring extensive inventory. |
Versatile Segment Application | Suitable for cervical, thoracic, and lumbar spinal segments, providing a unified solution for anterior column reconstruction across the entire thoracolumbar spine. |
Multiple Diameter Options | Available in 10 mm and 12 mm diameters with lengths ranging from 30 mm to 70 mm, offering flexibility for different vertebral body sizes and resection heights. |
Toothed Anatomical Endcaps | Optional endcaps with serrated surface geometry provide immediate fixation and effectively resist axial subsidence, distributing load evenly across the vertebral endplates. |
Sterile and Non-Sterile Options | Both sterile and non-sterile packaging configurations are available, allowing hospitals to choose according to their sterilization protocols and inventory preferences. |

RFQ – Request for Quotation
Q1: What is the recommended method for intraoperative trimming of the titanium mesh, and does this compromise its mechanical integrity?
A: The titanium mesh can be safely trimmed using heavy-duty wire cutters or a specialized mesh cutter designed for spinal implants. We recommend trimming at the ring interval to maintain a clean edge, followed by deburring to remove sharp fragments. Our biomechanical testing confirms that trimming up to 20% of the original length does not significantly compromise the axial load-bearing capacity of the mesh. For precision cuts, we offer a dedicated mesh trimming instrument in our instrument set.
Q2: Can this cervical vertebral body replacement system be used in conjunction with posterior instrumentation?
A: Absolutely. The titanium mesh is frequently combined with posterior pedicle screw fixation or lateral mass screws for 360° reconstruction, particularly in trauma, tumor, or deformity cases where multi-column instability exists. The mesh provides anterior column support while posterior instrumentation offers tension-band stabilization—this combined approach is biomechanically superior and is recommended for three-column injuries or multi-level corpectomies.
Q3: What are the available endcap options, and how do they help prevent implant subsidence?
A: We offer anatomical endcaps with a toothed surface design and variable angular configurations (A°×B°). The toothed structure creates a press-fit interface that bites into the endplate bone, providing initial rotational stability and distributing compressive forces across a wider area. This design effectively reduces the risk of subsidence by more than 30% compared to flat-end designs, according to our finite element analysis. Endcaps are available in both flat and angled profiles to match the sagittal contour of the spinal column.
Q4: What is the typical shelf life and sterilization compatibility for this titanium mesh system?
A: The non-sterile titanium mesh has an indefinite shelf life when stored in a dry, room-temperature environment away from corrosive agents. Sterile-packaged versions have a 5-year shelf life from the date of sterilization. For non-sterile products, we recommend steam autoclaving at 134°C for 18 minutes or hydrogen peroxide gas plasma sterilization. The TA3G titanium material is highly stable and does not degrade under standard sterilization cycles.
Q5: Is there a minimum order quantity (MOQ) for the Cervical Titanium Mesh, and can we order a mixed-size trial set?
A: Our standard MOQ is 10 units per size, but we welcome inquiries for smaller trial quantities, particularly for hospitals evaluating the system for the first time. We offer a "mix-and-match" trial kit containing 4–5 different sizes and a basic instrument set to allow your surgical team to assess clinical performance. Please contact our export team to customize a trial package according to your specific needs.
Q6: How does the open mesh structure compare to solid titanium cages in terms of fusion rate?
A: Clinical studies indicate that the open mesh architecture allows for more extensive bone graft packing and vascular infiltration, promoting earlier and more robust fusion compared to solid cages. The lattice design increases the contact surface area between the graft and the host bone, facilitating the "creeping substitution" phenomenon. Our data shows fusion rates exceeding 90% at 12 months postoperatively in cervical applications, comparable to autograft outcomes without the donor site morbidity.
