Foot Rings are structural components used within Orthopedic External Fixation systems. They are specifically designed to form part of the External Fixator Frame around the Foot & Ankle region according to the requirements of Surgical Reconstruction and the planned Frame Configuration.
The product features an Open Foot Ring Geometry with multiple Connection / Fixation Holes distributed around the ring perimeter, providing several attachment points for compatible components such as Connecting Rods, Clamps, Wire Fixation Elements, or other External Fixation System components according to the system design.
According to the provided data, the product family is listed under the general reference:
Cat. No.: AMS 602.004
The range is available in five progressively sized configurations: 80, 100, 120, 140, and 160 mm, with a consistent 20 mm increment between consecutive sizes.
This variation in sizes supports selection of the appropriate Foot Ring Size according to Foot Anatomy, Ankle Region, Required Frame Clearance, Fixation Site, and the characteristics of the planned External Fixation Construct.
Each size carries an individual Cat. No. and GTIN Number, supporting Product Identification, Traceability, Surgical Set Preparation, Procurement, Inventory Management, and Stock Control.
Product Description
A Foot Ring is a Structural Frame Component used as part of Circular / Modular External Fixation systems in the foot and ankle region.
The ring functions as part of the external frame and is connected to bone fixation elements and other structural components within the fixation system.
Its general relationship within the construct can be represented as follows:
Bone Fixation Element → Wire / Pin Interface → Connector / Rod → Foot Ring → External Fixation Frame
It differs from a Standard Circular Ring through its open geometry, which is suitable for constructing a Frame around the foot region according to the surgical fixation system being used.
Product Components and Design
- Foot Ring Body
The main body of the ring, designed with an open Foot-Specific Frame Geometry to function as one of the primary structural components of the External Fixator.
- Multiple Connection Holes
The product features multiple holes distributed around the ring perimeter, providing different attachment points for compatible Connecting Components.
Depending on the fixation system design, these connection points may be used with:
- Connecting Rods
- Wire Fixation Components
- Pin Interfaces
- Clamps
- Other Modular External Fixation Components
- Open Frame Geometry
The Foot Ring features an open geometry rather than a Complete Circular Ring, providing a configuration specifically intended for the foot region within the External Fixation System.
- Peripheral Structural Section
The peripheral portion of the ring forms the main Structural Frame, carries the Connection Holes, and contributes to construction of the Final Fixator Construct.
- Size-Specific Configuration
The product is available in five different sizes:
80 / 100 / 120 / 140 / 160 mm
providing multiple Frame Dimensions according to the anatomical region and clinical requirements.
Product Use
Foot Rings are used within compatible Foot & Ankle External Fixation systems to construct a Structural Frame around the target anatomical region.
Depending on the approved indications of the fixation system, they may be used in applications such as:
- Foot External Fixation
- Ankle External Fixation
- Fracture Stabilization
- Bone Segment Stabilization
- Foot & Ankle Reconstruction
- Circular / Modular External Fixator Constructs
- Selected Deformity Correction or Limb Reconstruction applications when included within the official indications
Selection of the appropriate Ring Size depends on factors including:
- Foot Anatomy
- Ankle Anatomy
- Anatomical Region
- Required Frame Clearance
- Fixation Site
- Wire / Pin Position
- Frame Geometry
- Preoperative Planning
- Intraoperative Frame Assembly
The Final Frame Configuration should be determined by a Qualified Orthopedic Surgeon in accordance with the applicable IFU and Surgical Technique of the fixation system.
Key Benefits

20 mm increments
providing an organized range during Ring selection.
Multiple Connection Points
Foot Rings feature multiple holes that provide several attachment points for compatible system components.
Modular Frame Integration
They can be integrated with compatible External Fixation components such as:
- Connecting Rods
- Clamps
- Wire Interfaces
- Pin Components
- Other Frame Elements
Product Traceability
Each size has an individual Cat. No. and GTIN Number to support:
- Product Identification
- Product Traceability
- Procurement
- Inventory Management
- Stock Control
