4.5 mm Monoaxial Pedicle Screw Spine System 21 Pcs

The 4.5mm Monoaxial Pedicle Screw Spine System is an orthopedic implant system designed for use in compatible spinal fixation procedures. Pedicle screw systems are used by qualified surgeons to help stabilize selected spinal segments when indicated. This 21-piece set is intended for professional medical use, with the exact configuration and approved applications determined by the manufacturer's documentation.

Monoaxial Pedicle Screw Design

Monoaxial pedicle screws feature a fixed relationship between the screw and its head, unlike polyaxial designs that allow the head to move relative to the screw shaft. This fixed orientation may be appropriate for specific fixation techniques and construct requirements. The suitability of the monoaxial configuration depends on the patient's anatomy, surgical plan, and the specifications of the complete implant system.

Spinal Fixation Applications

Pedicle screw systems may be used in selected spinal stabilization procedures when clinically indicated. The precise indications for this 4.5mm system must be confirmed through the manufacturer's instructions for use, including the approved spinal levels, patient population, and compatible rods or connecting components. The 4.5mm measurement should be verified against the manufacturer's product specifications to establish exactly which component dimension it describes.

21-Piece System Configuration

This product is listed as a 21-piece system. The exact contents should be verified before purchase, as the title alone does not establish the number or type of screws, rods, connectors, instruments, or other components included. Confirm whether the set contains implant components only or includes any dedicated surgical instruments.

Material, Compatibility, and Handling

The implant material, available screw lengths, thread design, and connection specifications should be confirmed with the supplier or manufacturer. Components must be compatible with the same approved system and used according to the manufacturer's instructions. Do not combine implants from different systems unless compatibility is explicitly documented.

As an implantable medical device, this system requires appropriate professional evaluation, handling, and use. Sterilization requirements, packaging condition, traceability, and regulatory documentation should be reviewed before clinical use. Follow the manufacturer's instructions for storage, preparation, implantation, and any applicable single-use restrictions.

It is a spinal fixation system featuring monoaxial pedicle screws, which have a fixed relationship between the screw shaft and head. Its exact specifications and approved applications depend on the manufacturer.

2. What does monoaxial mean in a pedicle screw system?

Monoaxial means the screw head does not articulate freely relative to the screw shaft, unlike a polyaxial screw head.

3. How many pieces are included in this system?

The product title specifies 21 pieces. The exact components and quantities should be confirmed with the supplier before purchase.

4. What does the 4.5mm measurement refer to?

The title identifies the system as 4.5mm, but the precise dimension represented by this measurement should be verified in the manufacturer's specifications.

5. What procedures is this system designed for?

It is intended for spinal fixation procedures approved for the specific system. The manufacturer’s instructions for use determine the appropriate indications and spinal levels.

6. What material are the pedicle screws made from?

The material is not specified in the product title. Confirm the implant material and applicable material standards with the manufacturer.

7. Are rods included with the 21-piece system?

The title does not confirm whether rods or connecting components are included. Request a detailed packing list before ordering.

8. Can this system be used with other pedicle screw systems?
