Introduction
The document describes a titanium mesh implant designed as a substitute following total or subtotal vertebrectomy. The implant aims to maintain intervertebral body height, restore physiological spinal curvature, provide stable biological and mechanical conditions for bone fusion, and facilitate ease of cutting, operation, and observation.

Indications
The implant is intended for:

• Filling vertebral body defects;
• Reconstruction of cervical vertebral body after trauma or tumor resection;
• Stable reconstruction following cervical vertebral tuberculosis debridement.

Features & Benefits
The implant features a mesh structure that promotes all-around bone growth and a stable triangular hollow design allowing customizable length by cutting. It is compatible with X-ray and MRI imaging without causing artifacts. Titanium mesh end caps increase contact area with adjacent vertebral end plates, reducing risks of collapse and subsidence.

Components and Specifications
The implant is available in various diameters and lengths:

• Diameters: Φ10, Φ12, Φ14, Φ16, Φ18, Φ20, Φ22, Φ24 mm
• Lengths: Ranging from 10 mm to 100 mm, with intervals depending on type and diameter.

Two main types are described:
Type I: Diameter and length combinations with specific interval increments (e.g., 10x14 mm with 1 mm intervals, 13x17 mm with 2 mm intervals, etc.)
Type II (Titanium Mesh Type IV): Available in diameters Φ10 to Φ24 mm, with length intervals varying from 1 mm to 8 mm depending on diameter. Available with 0° and 5° angles and thickness options of 1 mm and 3 mm.

Summary of Key Parameters
- Diameter range: 10 mm to 24 mm
- Length range: 10 mm to 100 mm
- Length intervals vary by diameter and type (1 mm to 8 mm)
- Angles available: 0° and 5°
- Thickness options: 1 mm and 3 mm
- End caps enhance stability and reduce subsidence risk

Critical Considerations
The implant must be selected and cut according to practical surgical requirements. The mesh design supports biological integration, and imaging compatibility facilitates postoperative assessment. The end caps are crucial for mechanical stability.
