FAQs of Double Lock Polyaxial Screw:

Q: How does the double lock mechanism benefit spinal fixation procedures?

A: The double lock mechanism enhances screw stability and torque resistance, reducing the risk of screw loosening or migration during and after surgery. This provides surgeons with greater confidence in achieving long-term spine stabilization.

Q: What is the process for sterilizing the Double Lock Polyaxial Screw before use?

A: The screws are provided pre-sterilized using either Ethylene Oxide (EtO) or autoclave methods. This ensures the implant is sterile and ready for surgical use upon opening from its blister pack or sterile box packaging.

Q: When should a polyaxial screw with a self-tapping thread be used in spinal surgery?

A: These screws are ideal for lumbar and thoracic spine fixation procedures, especially when precise anatomical alignment and secure implant anchorage are essential. The self-tapping design simplifies insertion into bone and is commonly used in complex or multi-level fixations.

Q: Where can surgeons use the Double Lock Polyaxial Screw system?

A: This system is designed for orthopedic spine surgeries and can be used in hospitals, surgical centers, or clinics specializing in spinal procedures. The universal rod compatibility (5.5mm/6.0mm) supports wide application in various healthcare institutions.

Q: What are the dimensions and measurement ranges available for this implant?

A: Screws are available in custom lengths typically ranging from 30mm to 60mm, with diameters spanning from 4.5mm to 7.0mm. These options allow surgeons to select the most appropriate size for each patients spinal anatomy.

Q: How should the screws be stored to maintain sterility and shelf life?

A: Maintain the screws in their original blister pack or sterile box in a cool, dry environment. Keeping the original packaging intact supports the 5-year shelf life and ensures the screw remains contamination-free until use.
