The Cancellous Screws with Flat Head are a range of Orthopedic Bone Fixation Screws designed for fixation within areas of Cancellous Bone as part of orthopedic and internal fixation procedures compatible with the surgical system being used.
The product features a Cancellous Thread Profile combined with a Flat Head Configuration. The threaded section is designed to achieve mechanical engagement within cancellous bone, while the flat head provides a geometry suitable for positioning within the Fixation Construct according to the specified surgical technique.
According to the supplied technical data, the product material is identified by the abbreviation Ti, referring to Titanium. The screws are available in five total lengths, ranging from 25 mm to 45 mm in consistent 5 mm increments. This graduated range allows the surgeon to select the appropriate screw length according to Bone Anatomy, bone thickness, fixation site, and intraoperative measurement.
Each screw length carries an individual AMS Product Code, supporting accurate implant selection and facilitating Surgical Set Preparation, Inventory Management, Procurement, and Stock Control.
What Are Cancellous Screws with Flat Head?
A Cancellous Screw is a bone screw featuring a thread geometry designed specifically to achieve fixation within regions of cancellous bone.
The thread design of Cancellous Screws differs from that of certain Cortical Screws, as it is adapted to the characteristics of Cancellous Bone to provide Mechanical Engagement within the target bone structure.
The Flat Head version features a relatively low-profile head, providing a compact configuration when the screw is incorporated into an appropriate Orthopedic Fixation Construct.
This product range is available in five different lengths, allowing the surgeon to select the Screw Length that corresponds to the required fixation depth and trajectory.
Product Components and Design
- Flat Screw Head
The upper portion of the screw, designed with a Flat Head Geometry that allows manipulation during insertion and provides a head profile compatible with the product design.
- Drive Interface
The screw head incorporates an Instrument Engagement Feature that allows the compatible insertion instrument to apply the required Insertion Torque during screw placement.
The exact type and dimensions of the Drive Interface are not specified in the supplied product table. Therefore, the approved Technical Datasheet or Surgical Technique should be consulted before publishing these specifications.
- Screw Shaft
The longitudinal body of the bone screw connecting the head to the threaded section and providing the required length to reach the target fixation area.
- Cancellous Thread
The threaded section of the screw designed to achieve engagement within Cancellous Bone.
The Thread Pitch, Major Diameter, Core Diameter, and detailed thread dimensions are not specified in the supplied product data.
- Distal Tip
The distal end of the screw, designed to assist guidance of the screw along the prepared trajectory according to the approved Surgical Technique.
Product Application
The Cancellous Screws with Flat Head are used in Internal Bone Fixation applications requiring fixation within cancellous bone regions, according to the approved indications and surgical system.
In general, cancellous screws may be used in orthopedic fixation procedures such as:
- Fixation of Bone Fragments in areas containing cancellous bone.
- Selected Fracture Fixation applications.
- Bone Reconstruction Procedures.
- Fixation of compatible Orthopedic Constructs.
- Use as part of an internal fixation system according to the manufacturer’s instructions.
The appropriate screw length is selected based on:
- Bone Anatomy
- Fracture / Fixation Site
- Required Screw Trajectory
- Bone Depth
- Intraoperative Measurement
- The Implant Construct being used
Final selection and use should be determined by a Qualified Orthopedic Surgeon in accordance with the approved IFU and Surgical Technique.
Key Benefits
Cancellous Bone Engagement
