The Cancellous Screw 6.5 MM Partially Threaded [St. St.] is a component used within Orthopedic Internal Fixation systems. It is designed as a bone screw with a nominal diameter of 6.5 mm and a Partial Thread Configuration for use in Cancellous Bone Fixation applications according to the approved indications and surgical technique of the system.
The product incorporates a design combining a Threaded Distal Section with a Smooth / Unthreaded Shank. This geometry is characteristic of Partially Threaded Screws and allows thread engagement within a selected portion of the bone according to the fixation technique being used.
This type of screw may be used as part of a Lag Screw Fixation technique when the screw trajectory, thread position, and surgical plan are appropriate, supporting an Interfragmentary Compression concept when applied according to accepted surgical fixation principles.
According to the supplied product data, the screw is manufactured from Stainless Steel [St. St.], has a nominal diameter of 6.5 mm, and a total length of 30 mm under product code AMS 104.265.030S.
The clear coding system facilitates implant identification and preparation within the Surgical Set, while also supporting Procurement, Inventory Management, and Stock Control.
Product Description
A Cancellous Screw is a bone screw designed with thread geometry suitable for engagement within regions of Cancellous Bone.
The designation Partially Threaded means that the screw thread extends along only part of the screw length, while another portion of the shaft remains unthreaded.
The primary specifications of the listed product are:
- Nominal Diameter: 6.5 mm
- Thread Configuration: Partially Threaded
- Material: Stainless Steel
- Total Length: 30 mm
- Product Code: AMS 104.265.030S
The screw should be selected and used according to the fixation site, Bone Anatomy, screw trajectory, and surgical plan.
Product Components and Design
- Screw Head
The proximal portion of the screw, designed to engage with the compatible insertion instrument during fixation.
The screw head allows application of the required Insertion Torque according to the approved Surgical Technique.
- Drive Interface
The screw head incorporates an Instrument Engagement Feature / Drive Recess designed to connect with the appropriate driver.
The exact type and dimensions of the Drive Interface are not specified in the supplied product data.
- Smooth / Unthreaded Shank
The unthreaded middle portion of the screw body, representing one of the characteristic features of the Partially Threaded Design.
- Cancellous Threaded Section
The distal threaded portion is designed to achieve Mechanical Engagement within Cancellous Bone.
The supplied product table does not specify:
- Thread Pitch
- Thread Length
- Core Diameter
- Major Diameter
- Thread Profile
Therefore, numerical values for these parameters should not be published without official technical documentation.
- Distal Tip
The distal end of the screw is designed to advance along the prepared bone pathway according to the approved surgical technique.
- Stainless Steel Construction
The material is identified as:
[St. St.] – Stainless Steel
However, the exact Stainless Steel Grade or applicable ASTM / ISO Material Specification is not provided in the available product data.
Product Application
The Cancellous Screw 6.5 MM Partially Threaded [St. St.] is used within Internal Bone Fixation applications requiring a screw designed for engagement with cancellous bone.
According to the approved indications, it may be incorporated into:
- Cancellous Bone Fixation
- Fracture Fragment Fixation
- Internal Fixation Constructs
- Bone Fragment Stabilization
- Lag Screw Technique, when appropriate for the clinical case and surgical technique
Use of the screw depends on factors including:
- Bone Anatomy
- Bone Quality
- Fixation Site
- Fragment Thickness
- Screw Trajectory
- Required Fixation Depth
- Intraoperative Measurement
The final method of use should be determined by a Qualified Orthopedic Surgeon in accordance with the approved IFU and Surgical Technique.
