The Lateral Mass Cervical Screw (3.5 mm) is a titanium spinal fixation implant designed for use within compatible cervical lateral mass fixation systems according to the manufacturer’s approved indications and surgical technique.
The implant features a threaded shaft intended for mechanical engagement with cervical bone and a proximal screw head / connection interface designed to integrate with compatible cervical rods, plates, connectors, or other fixation components according to the specific system configuration.
According to the supplied catalog information, the implant is manufactured from:
Material: Titanium
The product family is listed under:
Cat. No.: AMS 501.035.000
The nominal screw diameter is:
Ø3.5 mm
The screw is available in 16 lengths ranging from 8 mm to 38 mm, giving the surgeon multiple options for implant selection according to cervical anatomy, lateral mass dimensions, fixation depth, screw trajectory, construct geometry, and intraoperative assessment.
Each configuration carries a dedicated Cat. No. and GTIN No., supporting accurate implant identification, product traceability, surgical set preparation, procurement, inventory management, and stock control.
Product Explanation
The Lateral Mass Cervical Screw (3.5 mm) is a spinal fixation screw used as part of a compatible cervical stabilization construct involving the lateral mass region.
A simplified fixation concept can be represented as:
Cervical Lateral Mass → 3.5 mm Fixation Screw → Compatible Cervical Fixation Component → Cervical Stabilization Construct
The threaded portion provides mechanical engagement with bone, while the proximal screw head forms the interface with the compatible spinal fixation system.

- Distal Tip
The distal portion forms part of the threaded bone-engagement geometry.
The catalog does not define whether the screw is self-tapping, self-drilling, or incorporates another specific tip configuration.
- Length-Specific Configurations
Available lengths are:
8 / 10 / 12 / 14 / 16 / 18 / 20 / 22 / 24 / 26 / 28 / 30 / 32 / 34 / 36 / 38 mm
Intended Use
The Lateral Mass Cervical Screw (3.5 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 lateral mass fixation.
- Posterior cervical stabilization constructs.
- Cervical rod-and-screw fixation.
- Multi-level cervical stabilization.
- Cervical spinal reconstruction procedures.
- Internal fixation of appropriate cervical vertebral segments.
Selection of the appropriate screw configuration depends on:
- Cervical anatomy.
- Lateral mass dimensions.
- Bone quality.
- Fixation site.
- Required fixation depth.
- Screw trajectory.
- Compatible rod / connector 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.
