Acetabular Ring [St. St.]

The Acetabular Ring [St. St.] is a component of Acetabular Reconstruction Systems used in Hip Arthroplasty procedures. It is designed as a Reinforcement Ring to support the Acetabular Construct and provide an additional component that may be used according to acetabular reconstruction requirements and the approved surgical technique of the system.

The product features a metallic Stainless Steel structure, according to the product name and supplied data, with a Ring-Shaped Acetabular Geometry incorporating multiple visible Fixation Apertures / Openings. These features allow the implant to be integrated into the compatible fixation construct in accordance with the approved Surgical Technique.

The range is available in 8 different sizes, starting at 44 mm and extending to 58 mm, with consistent 2 mm increments between consecutive sizes. This graduated range provides multiple options during Preoperative Planning and Intraoperative Sizing, allowing selection of the appropriate ring dimension according to bone anatomy and acetabular dimensions.

Each size carries an individual AMS Product Code, facilitating identification of the required implant during surgical preparation and supporting Procurement, Implant Inventory Management, Surgical Set Preparation, and Stock Control.

The Acetabular Ring should be selected and used only with compatible components and in accordance with the approved IFU and Surgical Technique of the system.

What Is an Acetabular Ring?

An Acetabular Ring, also known as an Acetabular Reinforcement Ring, is an orthopedic implant used as part of an Acetabular Reconstruction system in hip surgery.

The ring is positioned in the acetabular region to create a Reinforcement Construct according to the requirements of the case. It functions as a structural support component for compatible acetabular components within a Hip Reconstruction System.

This type of component may be used when the surgeon determines that Acetabular Reinforcement is required according to bone condition, the type of surgical procedure, and reconstruction requirements.

The exact Indications for Use should be determined according to the manufacturer’s official instructions.

Product Design and Components

1. Acetabular Reinforcement Ring Body

The main metallic body of the implant, designed with a geometry compatible with the acetabular region.

It functions as a Structural Reinforcement Component within the Acetabular Construct.

2. Stainless Steel Structure

The material specified for the product is:

Stainless Steel – St. St.

The exact Material Grade is not specified in the supplied product data.

3. Central Acetabular Opening

The design features a large Central Opening, which forms a major part of the ring geometry.

4. Fixation Apertures

The implant incorporates multiple Fixation Openings / Apertures of different sizes and positions within the ring body.

These features are used according to the fixation system and surgical technique compatible with the product.

The exact number, diameters, and types of Screw Holes or Fixation Points are not specified in the supplied product table and should therefore be confirmed using the approved Technical Datasheet.

5. Peripheral Ring Geometry

The peripheral portion of the implant is designed to conform to the Acetabular Reconstruction Area and forms the primary structural framework of the ring.

Product Application

The Acetabular Ring [St. St.] is used in Hip Arthroplasty and Acetabular Reconstruction applications when the surgical plan requires the addition of a reinforcement component to the acetabular side.

It may be incorporated into systems used for:

• Acetabular Reconstruction
• Hip Arthroplasty Procedures
• Revision Hip Reconstruction, when included within the approved indications
• Supporting the Acetabular Construct according to Bone Stock
• Cases requiring an additional Reinforcement Component, based on the surgeon’s assessment

The appropriate size is selected according to:

• Acetabular Anatomy
• Bone Stock
• Acetabular Dimensions
• Bone Defect Assessment
• Preoperative Imaging
• Preoperative Templating
• Intraoperative Sizing
• Compatibility with the Acetabular Reconstruction System

A Qualified Orthopedic Surgeon should determine the indication, implant size, and fixation method in accordance with the approved IFU and Surgical Technique.
