Spinal Rod – Precision Spinal Fixation Core for Orthopedic Reconstruction
The core component of a spinal internal fixation system is the spinal rod, primarily used to provide mechanical support during surgery, correct deformities, and assist in bone graft fusion. This product is made of high-strength biocompatible materials and can be used in conjunction with pedicle screws and transverse joints. It is suitable for various spinal segments and aims to ensure long-term postoperative stability.
Core Advantages
Utilizing medical-grade titanium alloy, the implants possess excellent biocompatibility and corrosion resistance. The low elastic modulus effectively mitigates stress shielding effects, ensuring long-term support strength while protecting adjacent bone tissue and facilitating bone remodeling.
A variety of sizes are available, with diameters ranging from 5.5mm and 6.0mm, and lengths from 50mm to 360mm. Both straight and pre-bent rods are included, providing a complete product matrix to adapt to different anatomical locations such as the cervical, thoracic, and lumbar spine, meeting the precision needs of various adult and pediatric surgeries.
Optimized Design for Stable Fixation
Compatible with multi-axial, break-off, and standard pedicle screws, featuring a secure interface that prevents slippage during surgery.
Works in tandem with crosslinks to enhance construct stability, especially for long-segment spinal fixation.
Curved rods are pre-shaped to mimic spinal lordosis/kyphosis, simplifying surgical contouring and reducing operative time.
Minimally Invasive & Clinical-Friendly FeaturesEngineered for percutaneous minimally invasive spinal surgeries, the rod's smooth surface facilitates easy insertion through small incisions. The compatible instrumentation (rod benders, holders, compressors) streamlines bending, placement, and locking, optimizing surgical workflow and reducing surgeon fatigue.
Versatile Compatibility with Spinal Fixation SystemsSeamlessly integrates with spinal rod systems (5.5mm, 6.0mm, 5.5/6.0 dual-size) and accessory components (crosslinks, pedicle screws), supporting a wide range of surgical approaches-from degenerative disease treatment to fracture fixation and deformity correction.

Frequently Asked Questions (FAQ)
Q: What advantages does titanium alloy offer for spinal rods compared to other materials?
A: Titanium alloy outperforms alternatives like stainless steel with its superior biocompatibility (reducing rejection risk), lower modulus of elasticity (minimizing stress shielding and bone resorption), and excellent corrosion resistance. It also supports long-term implantation without compromising structural integrity, making it ideal for spinal fixation.
Q: Can this spinal rod be used with both minimally invasive and open spinal surgical approaches?
A: Yes. The rod's design is compatible with both percutaneous minimally invasive surgery (MIS) and open procedures. Its smooth surface allows easy passage through small incisions in MIS, while its rigid structure and secure screw interface meet the stability demands of open surgeries for complex cases (e.g., severe deformity).
Q: How to select the appropriate diameter and length of the spinal rod for a patient?
A: Diameter selection depends on spinal segment and fixation strength needs: 5.5mm rods are suitable for cervical/short-segment lumbar fixation, while 6.0mm rods are preferred for long-segment or high-stress fixation (e.g., thoracic deformity). Length is determined by the number of fixed segments-measured via preoperative imaging to ensure full coverage of the target spinal levels.
Q: Is the spinal rod compatible with different types of pedicle screws (e.g., multi-axial, break-off)?
A: Absolutely. The rod is designed with a universal interface that fits multi-axial pedicle screws (for angular adjustment), break-off screws (for minimally invasive wound closure), and standard pedicle screws. It also works with crosslinks to enhance construct stability, making it versatile for various spinal fixation systems.
Q: Will the titanium alloy spinal rod interfere with postoperative imaging (e.g., MRI, CT)?
A: No. Titanium alloy is non-magnetic and produces minimal artifacts in MRI and CT scans. This allows clinicians to conduct clear postoperative imaging to monitor bone healing, spinal alignment, and implant position without interference, ensuring accurate follow-up and timely rehabilitation adjustments.
