The Cervical Screw (4.0 mm) is a titanium spinal fixation implant designed for use within compatible cervical spine internal fixation systems according to the manufacturer’s approved indications and surgical technique.
The implant features a threaded shaft designed for mechanical engagement with bone and a proximal screw head intended to interface with compatible cervical fixation components and surgical instrumentation according to the specific spinal system.
According to the supplied catalog information, the implant is manufactured from:
Material: Titanium
The product family is listed under:
Cat. No.: AMS 514.040.000
The nominal screw diameter is:
Ø4.0 mm
The product is available in 16 lengths ranging from 8 mm to 38 mm, providing multiple options for screw selection according to cervical anatomy, bone dimensions, fixation site, required screw depth, construct geometry, and intraoperative assessment.
Each configuration carries an individual Cat. No. and GTIN No., supporting accurate implant identification, product traceability, surgical set preparation, procurement, inventory management, and stock control.
Product Explanation
The Cervical Screw (4.0 mm) is a spinal fixation screw used as part of a compatible cervical stabilization construct.
A simplified fixation concept can be represented as:
Cervical Vertebra → Cervical Screw → Compatible Plate / Fixation Component → Cervical Fixation Construct
The threaded shaft provides bone engagement, while the proximal head interfaces with the compatible fixation system according to its design.
Product Components and Design
- Titanium Screw Body
The primary implant structure is manufactured from Titanium, according to the supplied product data.
- 4.0 MM Nominal Diameter
The product is identified in the catalog as:
Cervical Screw (4.0 mm)
indicating a nominal 4.0 mm screw configuration.
- Threaded Shaft
The screw incorporates a threaded shaft intended for fixation within bone.
The supplied catalog does not specify:
- Thread pitch
- Core diameter
- Thread profile
- Thread depth
- Self-tapping characteristics
- Proximal Screw Head
The screw head is designed to interface with compatible fixation components and instrumentation.
The exact drive interface and locking mechanism are not specified in the supplied data.
- Distal Tip
The distal portion forms part of the screw’s bone-engagement geometry.
The catalog does not confirm whether the design is self-drilling, self-tapping, or another specific tip configuration.
- Length-Specific Configurations
Available lengths include:
8 / 10 / 12 / 14 / 16 / 18 / 20 / 22 / 24 / 26 / 28 / 30 / 32 / 34 / 36 / 38 mm
Intended Use
The Cervical Screw (4.0 mm) is intended for use within compatible cervical spine fixation systems, according to the manufacturer’s approved indications and Instructions for Use.
Potential applications, where included within the approved indications, may include:
- Cervical spine stabilization.
- Cervical plate-and-screw fixation constructs.
- Cervical spinal reconstruction.
- Internal fixation of appropriate cervical vertebral segments.
- Compatible anterior or posterior cervical fixation systems.
- Fixation within compatible cervical plate, lateral mass, or related constructs.
Selection of the appropriate screw configuration depends on:
- Cervical anatomy.
- Bone dimensions.
- Bone quality.
- Fixation site.
- Required screw depth.
- Screw trajectory.
- Compatible implant system.
- Preoperative planning.
- Intraoperative assessment.
The implant should be selected and inserted by a qualified spine surgeon in accordance with the approved surgical technique and IFU.
