Orthopedic Micro Surgery Spinal Monoaxial Pedicle Screw

The Orthopedic Micro Surgery Spinal Monoaxial Pedicle Screw is a specialized spinal fixation implant designed for use in compatible posterior spinal instrumentation systems. It is intended to provide a secure anchoring point within the vertebral pedicle for spinal stabilization and fixation procedures performed according to the surgeon’s selected technique and the applicable implant system.

A monoaxial pedicle screw features a fixed orientation between the screw shaft and the screw head. Unlike polyaxial designs that allow angular movement of the head relative to the screw shaft, the monoaxial configuration maintains a predetermined alignment. This characteristic can be useful in fixation constructs where controlled screw-head orientation and consistent rod engagement are required.

The screw is designed to work as part of a compatible spinal fixation construct rather than as a standalone device. Depending on the system, a pedicle screw may be combined with longitudinal rods and other compatible components to create a stabilized construct. Exact compatibility between the screw, rod, locking mechanism, and insertion instruments must be confirmed before clinical use.

The pedicle screw’s threaded shaft is designed for placement within the vertebral pedicle and appropriate vertebral bone according to the surgical plan. Correct screw trajectory, depth, size selection, and placement are determined by the surgeon based on patient anatomy, imaging, pathology, and the requirements of the selected fixation system.

Monoaxial pedicle screws may be considered in various spinal fixation applications where a fixed screw-head orientation is appropriate. Their potential use depends on the specific spinal level, anatomy, surgical approach, fixation strategy, and implant system. They may be incorporated into constructs used in selected spinal stabilization and fusion procedures.

The compact design of a micro-surgery-oriented spinal fixation component can be suitable for procedures where controlled instrumentation and precise implant handling are important. However, the term “micro surgery” does not by itself establish a particular surgical approach or indication; the appropriate application depends on the specific implant design, labeling, and surgical technique.

Implant selection is an important part of spinal fixation planning. Available screw diameters, lengths, thread profiles, head dimensions, and connection interfaces may vary between systems. The correct size should be selected based on anatomical requirements and the compatible implant system. Instruments used for preparation, insertion, and final tightening should correspond to the specific screw design.

As an implantable medical device, this product requires appropriate surgical evaluation, handling, and clinical use by qualified healthcare professionals. It should not be assumed to be universally compatible with other manufacturers’ rods, drivers, locking caps, or spinal fixation components unless compatibility has been specifically established.

Product Specifications

FAQs

What is a monoaxial pedicle screw?

A monoaxial pedicle screw is a spinal fixation screw with a fixed relationship between the screw shaft and screw head. It is designed to provide a predetermined screw-head orientation within a compatible spinal fixation construct.

What is a spinal pedicle screw used for?

A pedicle screw is used as an anchoring component in spinal fixation constructs. Compatible screws may be connected with rods and other components to provide stabilization according to the selected surgical technique.

What is the difference between monoaxial and polyaxial pedicle screws?

A monoaxial screw has a fixed screw-head orientation, while a polyaxial screw allows the head to articulate relative to the screw shaft. The appropriate design depends on the fixation system and surgical requirements.

Can this pedicle screw be used with any spinal rod?

No. The screw should be used only with compatible rods, locking components, and other parts of the corresponding spinal fixation system. Compatibility should be verified before implantation.

Are different sizes available?

Spinal pedicle screws are commonly manufactured in different diameters and lengths. The available sizes for this product depend on the specific configuration and should be selected according to anatomical and surgical requirements.

Is the screw suitable for microspinal surgery?

The product title identifies it as a micro-surgery spinal pedicle screw, but its precise clinical application depends on the manufacturer’s specifications, labeling, implant system, and surgeon’s chosen technique.

Does the product include the insertion instruments?

The product is a pedicle screw implant. Insertion drivers, taps, guides, rods, locking caps, and other instrumentation should not be assumed to be included unless specifically listed.

Who should select and implant a spinal pedicle screw?

Implant selection and placement should be performed by appropriately qualified spine or orthopedic surgical professionals using the applicable implant system’s instructions and surgical technique.
