Product Explanation
The Cannulated Screw Ø 3.7 mm, Partial Thread is an orthopedic fixation screw intended to form part of a compatible internal fixation construct.
A simplified fixation concept can be represented as:
Guide Wire / Prepared Fixation Path → Cannulated 3.7 mm Partial-Thread Screw → Compatible Bone / Fixation Construct
The product combines three clearly supplied characteristics:
Cannulated
Ø 3.7 mm
Partial Thread
The cannulated designation indicates the presence of an axial internal lumen designed for use with compatible guide-wire-based instrumentation according to the approved surgical technique.
The partial-thread configuration means that only part of the screw shaft carries bone-engaging threads, while another section remains unthreaded.
The exact length of the threaded and unthreaded portions is not provided in the supplied image.
Product Components and Design
- Cannulated Screw Body
The product is specifically identified as:
Cannulated Screw
indicating an internal axial lumen through the screw body.
The supplied image visually shows a central opening at the screw head, consistent with the cannulated designation.
However, the exact:
- Cannulation diameter.
- Guide-wire diameter.
- Guide-wire compatibility.
- Cannulation tolerances.
- Internal lumen geometry.
are not provided.
The safest technical wording is:
Cannulation: Present — exact internal diameter and guide-wire compatibility not specified
- Ø 3.7 mm Nominal Diameter
The product title specifies:
Ø 3.7 mm
as the nominal screw diameter.
The supplied image does not separately specify:
- Major thread diameter.
- Minor / core diameter.
- Thread depth.
- Thread pitch.
- Dimensional tolerances.
These should be confirmed from the manufacturer’s official dimensional drawing.
- Partial-Thread Configuration
The product is specifically identified as:
Partial Thread
The supplied image visually shows a threaded distal section and a comparatively smooth central shaft region.
This distinguishes the product from a fully threaded screw configuration.
The exact:
- Threaded length.
- Unthreaded shaft length.
- Thread-to-shaft transition.
- Thread pitch.
- Thread depth.
are not supplied.
- Threaded Distal Section
The distal portion of the screw visibly incorporates an external thread profile.
The exact thread geometry should not be estimated from the image.
The manufacturer’s technical drawing should be used to establish:
- Thread pitch.
- Thread depth.
- Thread lead.
- Core diameter.
- Thread flank geometry.
- Smooth / Unthreaded Shaft Section
A substantial portion of the screw body appears visually unthreaded.
This is consistent with the supplied Partial Thread designation.
The exact axial length of the unthreaded section is not specified and may vary with screw length; this should be confirmed from the official product drawings.
- Screw Tip
The supplied image shows a defined distal screw tip.
However, the product title does not state:
Self Tapping
or
Self Drilling
Therefore, neither feature should be added to the technical sheet without supporting documentation.
The exact tip geometry and preparation requirements should be confirmed from the manufacturer’s surgical technique.
- Screw Head and Drive Interface
The supplied image shows a proximal screw head containing an insertion interface and a central opening consistent with cannulation.
However, the exact drive type is not specified.
Therefore, the product should not be described as:
Hex / Torx / Star / Stardrive / other
without official confirmation.
The exact:
- Head diameter.
- Head height.
- Head profile.
- Drive interface.
- Compatible screwdriver.
should be confirmed from the manufacturer’s system documentation.

Material Options
According to the supplied product data, 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 Cannulated Screw Ø 3.7 mm, Partial Thread 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 orthopedic fixation where a 3.7 mm cannulated partial-thread screw is specified by the manufacturer.
The exact anatomical indications, compatible fixation components, guide-wire requirements, screw placement technique, and preparation requirements are not supplied in the image and should be confirmed from the official product documentation.
Screw selection may depend on factors including:
- Anatomical location.
- Bone dimensions.
- Required screw diameter.
- Required screw length.
- Required partial-thread configuration.
- Bone quality.
- Required fixation construct.
- Compatible guide wire.
- Screw trajectory.
- Compatible drill or preparation instruments.
- Compatible depth gauge.
- 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
Cannulated Design
The product is specifically identified as:
Cannulated
indicating an internal lumen intended for use within a compatible guided fixation system.
The exact guide-wire size should be confirmed from official documentation.
Partial-Thread Configuration
The product is specifically identified as:
Partial Thread
providing a threaded distal region combined with an unthreaded shaft section.
The exact mechanical and clinical role of the partial-thread geometry should be confirmed from the manufacturer’s approved documentation.
Ø 3.7 mm Nominal Diameter
The product provides a nominal:
3.7 mm screw diameter
within the compatible orthopedic fixation system.
2 mm Length Increments
The complete range uses:
2 mm increments
from:
10 mm to 38 mm
providing closely spaced length selections.
15 Length Configurations
The complete supplied range includes:
10 / 12 / 14 / 16 / 18 / 20 / 22 / 24 / 26 / 28 / 30 / 32 / 34 / 36 / 38 mm
for a total of:
15 length configurations
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: Ø 3.7 mm
- 1 cannulated configuration
- 1 partial-thread configuration
- 15 length options
- 2 material options: SS316L / Titanium
If every listed length is available in both materials, this could theoretically represent:
15 × 2 = up to 30 basic length × material configurations
The exact commercial matrix should be confirmed from the official Cat. No. / GTIN table.
