The Poly Axial Screw (7.0 mm) is a titanium spinal fixation implant designed for integration within compatible posterior spinal instrumentation systems according to the manufacturer’s approved indications and surgical technique.
The implant combines an elongated threaded bone-engagement shaft with a proximal polyaxial fixation head. The polyaxial head is designed to allow controlled orientation relative to the screw shaft within the mechanical limits of the corresponding spinal fixation system, facilitating alignment with compatible rods during construct assembly.
According to the supplied catalog:
Material: Titanium
General Cat. No.: AMS 501.070.000
Nominal Diameter: 7.0 mm
The product is available in 12 length configurations ranging from 25 mm to 80 mm, providing a broad selection for implant planning according to vertebral anatomy, bone dimensions, required fixation depth, screw trajectory, rod position, fixation level, and overall construct geometry.
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 Poly Axial Screw (7.0 mm) is a posterior spinal fixation screw intended to function as part of a compatible screw-and-rod stabilization construct.
A simplified fixation concept can be represented as:
Vertebra → Polyaxial Screw → Compatible Spinal Rod → Locking Component → Posterior Spinal Fixation Construct
The threaded shaft provides mechanical engagement with bone, while the polyaxial head provides the interface for compatible spinal rods and locking elements.
Product Components and Design
- Titanium Screw Body
The primary implant structure is manufactured from Titanium, according to the supplied product data.
- 7.0 MM Nominal Diameter
The catalog identifies the product as:
Poly Axial Screw (7 mm)
indicating a nominal 7.0 mm screw configuration.
- Threaded Bone-Engagement Shaft
The implant incorporates an elongated threaded shaft intended for mechanical engagement with vertebral bone.
The supplied catalog does not specify:
- Thread pitch
- Core diameter
- Thread depth
- Thread profile
- Self-tapping characteristics
- Polyaxial Fixation Head
The proximal head is designed to provide controlled orientation relative to the screw shaft and to receive compatible rod and locking components.
The exact polyaxial angular range is not specified in the supplied data.
- Distal Tip
The distal portion forms part of the threaded bone-engagement geometry.
- Length Configurations
Available lengths are:
25 / 30 / 35 / 40 / 45 / 50 / 55 / 60 / 65 / 70 / 75 / 80 mm
Intended Use
The Poly Axial Screw (7.0 mm) is intended for use within compatible posterior spinal fixation systems, according to the manufacturer’s approved indications and Instructions for Use.
Potential applications, where included within the approved indications, may include:
- Posterior spinal stabilization.
- Screw-and-rod fixation constructs.
- Multi-level spinal instrumentation.
- Spinal reconstruction constructs.
- Spinal deformity fixation systems.
- Compatible thoracic or lumbar posterior fixation systems.
Selection of the appropriate configuration depends on:
- Vertebral anatomy.
- Bone dimensions.
- Bone quality.
- Fixation level.
- Required screw depth.
- Screw trajectory.
- Rod position.
- Construct geometry.
- Preoperative planning.
- Intraoperative assessment.
The implant should be selected and inserted by a qualified spine surgeon according to the approved surgical technique and IFU.
