Half Rings are structural components used within Orthopedic External Fixation systems. They are designed with a Semi-Circular Ring Geometry to form part of the External Fixator Frame around the target anatomical region according to Surgical Reconstruction and Frame Configuration requirements.
The design incorporates multiple Connection / Fixation Holes distributed along the circumference of the Half Ring, providing several attachment points for compatible components within the External Fixation System, such as Connecting Rods, Clamps, Wire / Pin Interfaces, and other Modular Fixator components according to the system design.
According to the provided data, the product family is listed under the general reference:
Cat. No.: AMS 602.002
The range is available in 9 sizes, starting from 80 mm and extending to 240 mm, with a consistent increment of 20 mm between consecutive sizes.
This broad size range supports selection of the appropriate Half Ring according to Limb Anatomy, Anatomical Region, Required Frame Clearance, Fixation Site, and the planned External Fixator Construct.
Each size carries an individual Cat. No. and GTIN Number, facilitating Product Identification, Traceability, Surgical Set Preparation, Procurement, Inventory Management, and Stock Control.
Product Description
A Half Ring is a semi-circular Structural Component used within selected Circular / Modular External Fixation systems to form an external fixation frame around a limb or target bone region.
The Half Ring functions as a structural connection point for other fixation elements within the system. Its general role can be represented as follows:
Bone Fixation Element → Wire / Pin Interface → Connector / Rod → Half Ring → External Fixation Frame
The semi-circular design allows different Frame Configurations to be constructed according to anatomical and surgical requirements.
Product Components and Design
- Semi-Circular Ring Body
The main body of the product, designed in a Half-Circle / Semi-Circular Ring configuration to function as a structural element within the External Fixation Frame.
- Multiple Connection Holes
The Half Ring features multiple holes distributed along its perimeter, providing Multiple Connection Points for compatible components.
These connection points may be used within the system with:
- Connecting Rods
- Clamps
- Wire Interfaces
- Pin Fixation Components
- Other Modular Frame Elements
- Peripheral Structural Section
The circumferential portion of the Half Ring that forms the primary structural body of the component and carries the connection holes.
- Open Semi-Circular Geometry
The design is semi-circular and open compared with a Full Ring, providing a different Geometry during construction of the External Fixator Construct.
- Size-Specific Configuration
The product is available in a progressive range of sizes:
80 / 100 / 120 / 140 / 160 / 180 / 200 / 220 / 240 mm
Product Use
Half Rings are used within compatible External Skeletal Fixation systems to form part of the External Fixation Frame.
Depending on the system and its approved indications, they may be incorporated into applications such as:
- Circular External Fixation
- Modular External Fixation
- External Fracture Stabilization
- Bone Segment Stabilization
- Limb Reconstruction
- Orthopedic Reconstruction Procedures
- Frame Construction around different anatomical regions
- Selected Deformity Correction applications when included within the official system indications
Selection of the appropriate Half Ring Size depends on:
- Limb Anatomy
- Anatomical Region
- Required Ring Clearance
- Fixation Site
- Position of Wires / Pins
- Frame Geometry
- Surgical Planning
- Intraoperative Frame Assembly
The Final Frame Configuration should be determined by a Qualified Orthopedic Surgeon in accordance with the approved IFU and Surgical Technique.
