The Pedicle Spinal Polyaxial Screw and Rod Set is an orthopedic implant system intended for selected spinal stabilization and fixation procedures. Pedicle screw systems are used by qualified spine surgeons to create fixation constructs that support alignment and stability when clinically indicated. The suitability of a specific system depends on its design, approved indications, anatomical requirements, and compatibility among its components.

This product is described as a 14-piece set with a stated screw diameter of 5.5mm and screw lengths ranging from 35mm to 55mm. The exact distribution of screw lengths, number of rods, and any additional components should be confirmed with the supplier before ordering.

Polyaxial Screw Design

Polyaxial pedicle screws feature a screw head designed to move through an angular range relative to the screw shaft before final locking, depending on the system's mechanism. This design can help surgeons align the screw head with a connecting rod during assembly of a compatible spinal fixation construct.

The permitted movement, locking mechanism, and available adjustment range vary by manufacturer. These characteristics should be checked in the technical documentation rather than assumed from the product name alone. Only components specifically approved for use together should be assembled.

5.5mm Screw Diameter and Length Options

The product title specifies a 5.5mm screw diameter and available lengths between 35mm and 55mm. Screw length is an important selection factor in spinal instrumentation and must be assessed in relation to patient anatomy, the intended spinal level, and the planned fixation technique.

The title does not specify whether every length within the range is included or which quantities correspond to each length. The supplier should provide a detailed inventory and dimensional chart, including thread characteristics, shaft design, and the method used to measure screw length.

Rod-Based Spinal Fixation

Connecting rods are used in compatible pedicle screw systems to link screw heads and form a fixation construct. Rod diameter, length, contouring requirements, and connection design must match the specified screw system. The exact rod dimensions and number included in this 14-piece set are not provided in the product title.

Compatibility is essential because spinal implant systems may use proprietary connection geometries and locking components. Rods and screws should not be mixed across different systems unless the manufacturers explicitly confirm compatibility.

Materials and Implant Quality

The material composition of this particular set is not specified. Spinal implants may be manufactured from medical-grade titanium alloys or other implant materials, depending on the system. The exact alloy, applicable implant standards, and manufacturer documentation should be verified before purchase.

The product title alone does not establish regulatory approval, biocompatibility, sterility, or suitability for a particular patient. Healthcare facilities should review the relevant technical documents, traceability information, and applicable regulatory requirements.

Handling, Storage, and Clinical Considerations

Before use, qualified personnel should verify the implant specifications, component compatibility, packaging integrity, and traceability details. Implant selection, placement, and final construct assembly must follow the manufacturer's surgical technique and the treating surgeon's judgment.

Sterility status and single-use designation should be confirmed with the supplier. Implants supplied sterile should not be used if their packaging is damaged or sterility is uncertain. Storage and handling should follow the manufacturer's instructions.

The Pedicle Spinal Polyaxial Screw and Rod Set provides a specified screw diameter, a stated length range, and a 14-piece configuration for consideration in compatible spinal fixation applications. Confirming the exact contents, rod specifications, material, and system compatibility is essential before purchase or clinical use.

Product Specifications

Frequently Asked Questions

1. What is a pedicle spinal polyaxial screw and rod system?

It is an implant system used in selected spinal fixation procedures. Pedicle screws are placed according to the surgical plan and connected with compatible rods to form a stabilization construct.

2. What does polyaxial mean in spinal screws?

Polyaxial refers to a screw-head design that permits angular movement relative to the screw shaft before final locking, according to the specific system's mechanism.

3. What is the screw diameter of this set?

The product title specifies a screw diameter of 5.5mm.

4. What screw lengths are available?

The stated length range is 35mm to 55mm. Confirm the individual lengths and quantities included with the supplier.

5. How many pieces are included?

The product title specifies a total of 14 pieces. Request the complete packing list to identify the number of screws, rods, and any additional components.

6. What material are the screws and rods made from?

The material is not specified in the product title. Confirm the exact implant material and applicable technical documentation with the manufacturer or supplier.

7. Are the rods compatible with other 5.5mm pedicle screw systems?

Not necessarily. Compatibility depends on the connection geometry, locking mechanism, and manufacturer specifications. Use only components confirmed as compatible.

8. What procedures is this set used for?

It is intended for selected spinal fixation applications. The appropriate use depends on the system's approved indications, patient anatomy, and the treating spine surgeon's assessment.

9. Are the implants supplied sterile?

The product title does not specify sterility status. Confirm whether the implants are supplied sterile and review the manufacturer's instructions before clinical use.

10. What should be verified before ordering?

Confirm the exact 14-piece inventory, screw lengths, rod dimensions, material, system compatibility, sterility status, traceability, and applicable regulatory documentation.
