Lengthening Rods are structural components used within Orthopedic External Fixation systems, functioning as Connecting / Adjustment Rod Components that integrate with other External Fixator components to help establish the required Frame Geometry according to the surgical plan and system design.
This product range offers multiple lengths, starting from 60 mm and extending to 200 mm, allowing selection of an appropriate Rod Length according to Anatomical Region, Distance Between Frame Components, Ring Position, Required Frame Geometry, and the characteristics of the External Fixation Construct.
According to the provided product data, the family is listed under the general reference:
Cat. No.: AMS 602.017
The range includes six length configurations: 60, 80, 100, 120, 150, and 200 mm, with an individual Cat. No. and GTIN Number assigned to each variant.
This range provides the surgical team with flexibility during Preoperative Frame Planning and Intraoperative Frame Assembly. Lengthening Rods should only be used with compatible system components and in accordance with the approved IFU and Surgical Technique.
Individual coding for each length also supports Product Identification, Procurement, Product Traceability, Inventory Management, and Stock Control.
Product Description
A Lengthening Rod is a Structural Connecting Component used within selected External Skeletal Fixation systems to provide additional extension or a specific Length Configuration between components of the Fixator Frame.
Its general position within the system can be represented as follows:
Ring / Arch → Connector / Clamp → Lengthening Rod → External Fixator Component
The Rod Length is selected according to the required distance between Frame Components and the External Fixation Construct determined by the surgeon.
Product Components and Design
- Rod Body
The main longitudinal body of the component, functioning as a structural connecting element within the External Fixator system.
- Connection Interface
The design features Connection Elements at the ends of the Rod for attachment to compatible components.
The specific Thread Type or Connector Dimensions are not specified in the provided table.
- Lengthening / Extension Section
The section responsible for providing the specified Length Configuration for each variant.
The range is available in:
60 / 80 / 100 / 120 / 150 / 200 mm
- External Fixator Integration
The Rod is designed to function with compatible External Fixation components such as:
- Rings
- Half Rings
- C-Rings
- Arches
- Clamps
- Connecting Elements
according to the fixation system design.
Product Use
Lengthening Rods are used within compatible Orthopedic External Fixation systems as Structural Connection / Extension Elements within the Fixator Frame.
Depending on the system design and approved indications, they may be incorporated into:
- Circular External Fixation
- Modular External Fixation
- External Fracture Stabilization
- Bone Segment Stabilization
- Limb Reconstruction Constructs
- Connection or extension of spacing between Frame Components
- Orthopedic Reconstruction Procedures utilizing External Fixation
Selection of the appropriate Rod Length depends on:
- External Fixator Geometry
- Distance Between Frame Components
- Ring / Arch Position
- Anatomical Region
- Required Frame Clearance
- Construct Configuration
- Preoperative Planning
- Intraoperative Frame Assembly
The Final Construct should be determined by a Qualified Orthopedic Surgeon in accordance with the approved IFU and Surgical Technique.
