Pediatric Half Rings are structural components used within Pediatric Orthopedic External Fixation systems. They are designed with a Semi-Circular / Half-Ring Geometry to function as part of the External Fixator Frame used for bone fixation and reconstruction in pediatric orthopedic applications.
The design features multiple Connection / Fixation Holes distributed along the perimeter of the Half Ring, providing multiple attachment points for compatible components within the External Fixation system, such as Connecting Rods, Clamps, Wire Interfaces, or Pin Fixation Elements according to the system design and approved Surgical Technique.
According to the provided data, the product family is listed under the general reference:
Cat. No.: AMS 603.001
The range is available in two configurations listed as 90° and 120°. The availability of more than one Geometry Option allows the surgical team to select the appropriate Half Ring Configuration according to Pediatric Limb Anatomy, Fixation Site, Frame Geometry, and reconstruction requirements.
Each configuration carries an individual Cat. No. and GTIN Number, supporting Product Identification, Traceability, Surgical Set Preparation, Procurement, Inventory Management, and Stock Control.
Product Description
A Pediatric Half Ring is a semi-circular Structural External Fixation Component designed to function within External Skeletal Fixation systems intended for Pediatric Orthopedic applications.
It functions as part of the External Fixation Frame and is connected to fixation elements and other structural components within the system.
Its general role within the construct can be represented as follows:
Bone Fixation Element → Wire / Pin Interface → Connector / Rod → Pediatric Half Ring → External Fixation Frame
The semi-circular design provides an open geometry that allows different Frame Configurations compared with a Full Ring, according to clinical requirements and the fixation system being used.
Product Components and Design
- Semi-Circular Ring Body
The main structural body of the component, designed with a Half-Ring / Semi-Circular Geometry 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.
Depending on the system design, these connection points may be used with:
- Connecting Rods
- Clamps
- Wire Interfaces
- Pin Fixation Components
- Other Modular Frame Components
- Open Half-Ring Geometry
The design is open and semi-circular, providing a configuration distinct from a Complete Circular Ring.
- Pediatric-Specific Configuration
The product is classified within Pediatric External Fixation Components and is intended for construction of Frames used in pediatric orthopedic applications according to the fixation system instructions.
- Configuration Options
The product family is available in:
90° and 120°
However, the provided table does not definitively specify whether these values represent an Arc Angle, Opening Angle, or another geometric classification. Therefore, they should be retained as Configuration Values as listed until confirmed by the official Technical Datasheet.
Product Use
Pediatric Half Rings are used within compatible Pediatric External Fixation systems to form part of the Fixation Frame around the target anatomical region.
Depending on the approved indications of the fixation system, they may be incorporated into applications such as:
- Pediatric External Fracture Fixation
- Bone Segment Stabilization
- Pediatric Orthopedic Reconstruction
- Modular / Circular External Fixation Constructs
- Limb Reconstruction Procedures
- Selected Deformity Correction applications when included within the official indications
Selection of the appropriate configuration depends on:
- Pediatric Limb Anatomy
- Anatomical Region
- Fixation Site
- Required Frame Geometry
- Position of Wires / Pins
- Bone Segment
- Preoperative Planning
- Intraoperative Frame Assembly
The Final External Fixation Construct should be determined by a Qualified Orthopedic Surgeon in accordance with the approved IFU and Surgical Technique.
