Product Explanation
The Cortical Bone Screw, Self Tapping Ø 4.5 mm is an orthopedic fixation screw intended to form part of a compatible internal fixation construct.
A simplified fixation concept can be represented as:
Prepared Bone / Compatible Plate → 4.5 mm Cortical Screw → Thread Engagement → Internal Fixation Construct
The product is specifically identified as a:
Cortical Bone Screw
with a:
Self Tapping
design.
Its nominal diameter is:
Ø 4.5 mm
and the product family covers screw lengths from:
12 mm to 110 mm
using two different length-increment ranges.
Product Components and Design
- Cortical Screw Body
The implant consists of a metallic screw body incorporating a threaded shaft, distal tip, and proximal screw head.
According to the supplied product designation, it is specifically classified as a:
Cortical Bone Screw
The exact overall dimensions, core diameter, mechanical characteristics, and dimensional tolerances should be confirmed from the manufacturer’s technical drawings.
- Ø 4.5 mm Nominal Diameter
The supplied product title specifies:
Ø 4.5 mm
This represents the nominal screw diameter.
The supplied data does not separately define:
- Major thread diameter.
- Minor / core diameter.
- Thread pitch.
- Thread depth.
- Thread flank geometry.
- Thread tolerances.
These specifications should therefore be obtained from the official dimensional drawing.
- Self-Tapping Design
The product is specifically identified as:
Self Tapping
indicating a manufacturer-defined self-tapping feature.
The exact:
- Cutting flute geometry.
- Tip design.
- Thread-start geometry.
- Cutting characteristics.
- Drilling requirements.
- Tapping requirements.
are not defined in the supplied image and should be confirmed from the manufacturer’s surgical technique.
- Threaded Fixation Profile
The supplied product image visibly shows a threaded shaft extending along a substantial portion of the screw.
The thread profile is intended to engage compatible bone as part of an approved fixation construct.
The exact:
- Thread pitch.
- Thread depth.
- Thread lead.
- Threaded length.
- Core diameter.
are not specified in the supplied product data.
- Screw Tip
The screw incorporates a defined distal tip consistent with its Self Tapping product designation.
However, the exact tip geometry, cutting features, tip angle, and preparation technique cannot be reliably determined from the image alone.
- Screw Head and Drive Interface
The supplied image shows a proximal screw head containing an insertion interface.
The exact driver type is not stated.
Therefore, the technical sheet should not identify the interface as Hex, Torx, Star, or another drive type without official confirmation.
The exact:
- Head diameter.
- Head height.
- Head profile.
- Drive geometry.
- Compatible screwdriver.
should be confirmed from the manufacturer’s system documentation.
Length Configurations
According to the supplied product image, two length ranges are specified.
Range 1 — 12–88 mm in 2 mm increments
This provides 39 length options:
12 / 14 / 16 / 18 / 20 / 22 / 24 / 26 / 28 / 30 / 32 / 34 / 36 / 38 / 40 / 42 / 44 / 46 / 48 / 50 / 52 / 54 / 56 / 58 / 60 / 62 / 64 / 66 / 68 / 70 / 72 / 74 / 76 / 78 / 80 / 82 / 84 / 86 / 88 mm
Range 2 — 90–110 mm in 5 mm increments
This provides 5 length options:
90 / 95 / 100 / 105 / 110 mm
Therefore, the complete product family provides:
39 + 5 = 44 length configurations
Material Options
According to the supplied product information, the screw is available in:
SS316L
and
Titanium
The exact Titanium alloy or grade is not specified in the supplied image and should be confirmed from the manufacturer’s official material documentation.
Intended Use
The Cortical Bone Screw, Self Tapping Ø 4.5 mm is designed for use as part of a compatible orthopedic fixation system according to the approved indications, surgical technique, and Instructions for Use.
Potential applications may involve fixation through compatible orthopedic plates or other approved fixation components where a 4.5 mm cortical screw is specified.
The exact anatomical region and compatible implant systems are not stated in the supplied image.
Screw selection may depend on factors including:
- Anatomical location.
- Bone dimensions.
- Cortical bone thickness.
- Required screw diameter.
- Required screw length.
- Compatible plate or implant.
- Required fixation construct.
- Bone quality.
- Screw trajectory.
- Compatible drilling instrumentation.
- Compatible screwdriver.
- Preoperative planning.
- Intraoperative measurement.
The screw should be selected and implanted by a qualified orthopedic surgeon in accordance with the approved surgical technique and Instructions for Use.
Key Benefits
Self-Tapping Screw Design
The product is specifically identified as:
Self Tapping
providing a defined self-tapping configuration within the screw family.
The exact preparation and insertion requirements should be confirmed from the manufacturer’s technique guide.
Ø 4.5 mm Nominal Diameter
The product provides a defined:
4.5 mm nominal screw diameter
within a compatible orthopedic fixation system.
Wide Length Range
The product family covers:
12 mm to 110 mm
providing a broad screw-length selection.
Fine 2 mm Length Increments
From:
12 mm to 88 mm
the screw is available in:
2 mm increments
providing closely spaced length options throughout the majority of the range.
Extended 5 mm Length Increments
From:
90 mm to 110 mm
the screw is available in:
5 mm increments.
44 Length Configurations
The complete supplied range includes:
44 individual screw lengths
across the two length ranges.
Two Material Options
According to the supplied product data, the screw is available in:
SS316L
and
Titanium
Multiple Product Variants
Based strictly on the supplied information, the product family includes:
- 1 nominal diameter: 4.5 mm
- 44 length options
- 2 material options: SS316L / Titanium
If every listed length is available in both materials, this could theoretically represent:
44 × 2 = up to 88 basic length × material configurations
The exact commercial matrix should be confirmed from the official Cat. No. / GTIN table.
