Intended Use

The AGILON® XO Shoulder Replacement System is indicated for use for total or hemi shoulder replacement in cases of:

  • · Non- inflammatory deqenerative joint disease including osteoarthritis and avascular necrosis,
  • · Post-traumatic osteoarthritis.
  • · Fractures,
  • · Rheumatoid arthritis.

The main indications for the implantation of an AGILON® hemi shoulder prosthesis are:

  • · Multi-fragmental comminuted fractures of the humeral head,
  • · 3- and 4-Fragment-fractures of the proximal humerus,
  • · Head-splitting fractures,
  • · Dislocated head-splitting fractures,
  • · Humeral head depression with more than 40% of joint surface depressed,
  • · Interlocking chronic dislocation with deep HILL-SACHS lesion,
  • · Fracture instability following internal fixation attempt in 3-fragment fractures (secondary dislocation, material loosening),
  • · Posttraumatic humeral head necrosis,
  • · Omarthrosis.

AGILON® CTA heads are destined for treatment of stable types of rotator cuff tear arthropathy. In order to achieve satisfactory results with the CTA heads the fornix humeri and the subscapularis tendon must be intact. A CTA cap is intended for the use as a hemi-arthroplasty, to treat a patient after an inverse shoulder has failed. It is not combined with a glenoid implant. It can be used in primary and revision cases.

The main indications for the implantation of an AGILON® inverse (reverse) shoulder prosthesis are:

  • · Rotator cuff tear arthropathy,
  • · Chronic trauma shoulder,
  • · Decentering of the humeral head after implantation of a humeral head prosthesis.

Please note, that the patient's joint must be anatomically and structurally suited to receive the selected implant(s), and a functional deltoid muscle is necessary.

In case of revision surgery the available bone stock has to be evaluated to allow for implantation of well-fixed stems. Conversion of the system can be performed in revision cases as follows:

  • · From Hemi Shoulder Arthroplasty to Anatomic Total Shoulder Arthroplasty
  • · From Hemi Shoulder Arthroplasty to Hemi CTA Shoulder Arthroplasty
  • · From Hemi Shoulder Arthroplasty to Inverse (Reverse) Total Shoulder Arthroplasty
  • · From Inverse (Reverse) Total Shoulder Arthroplasty to Hemi Shoulder Arthroplasty as salvage procedure
  • · From Inverse (Reverse) Total Shoulder Arthroplasty to Hemi CTA Shoulder Arthroplasty as salvage procedure
  • From Anatomic Total Shoulder Arthroplasty to Inverse (Reverse) Total Shoulder Arthroplasty
  • · From Anatomic Total Shoulder Arthroplasty to Hemi CTA Shoulder Arthroplasty
    The device is intended for adults.

AI/ML Overview

The provided text describes a 510(k) premarket notification for the AGILON® XO Shoulder Replacement System, focusing on new cancellous screws. However, it does not include detailed acceptance criteria or a comprehensive study report with the specific information requested in your prompt regarding AI/algorithm performance.

The document primarily focuses on demonstrating substantial equivalence to a predicate device through engineering analysis and limited performance testing of the new cancellous screws. Therefore, I cannot provide all the requested information.

Here's what I can extract and infer from the provided text, along with what is explicitly not available:


1. A table of acceptance criteria and the reported device performance

Acceptance Criteria (for cancellous screws)Reported Device Performance (type of testing)
Sufficient performance for intended use (specific numeric criteria not provided)- Torsional Properties (ASTM F543)- Driving Torque (ASTM F543)- Axial Pull-out Strength (ASTM F543)
Predetermined acceptance criteria met (specific numeric criteria not provided)Testing demonstrated sufficient performance and met predetermined acceptance criteria.
Biocompatibility (per ISO 10993-1)Evaluation completed per ISO 10993-1.
Cleaning, sterilization, packaging, shelf-life, and endotoxin standards metLeveraged from the predicate AGILON® XO Shoulder Replacement System (K231657).

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

  • Sample Size: Not specified for the cancellous screw testing (Torsional Properties, Driving Torque, Axial Pull-out Strength).
  • Data Provenance: Not specified. The manufacturer is implantcast, GmbH, located in Buxtehude, Germany, but the location where testing was performed is not mentioned. The study is part of a 510(k) submission, generally involving laboratory testing rather than clinical data provenance in this context.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

Not applicable. This device is a mechanical shoulder replacement system, and the testing described is mechanical performance (e.g., strength, torque) and biocompatibility, not an AI or diagnostic device that requires expert ground truth for interpretation of medical images or conditions.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. This device is a mechanical shoulder replacement system, not a diagnostic or AI device that requires adjudication of expert interpretations.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This is a medical device (shoulder replacement system), not an AI-assisted diagnostic tool. No AI component or human reader study is mentioned.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This is a medical device (shoulder replacement system), not a standalone algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

For the mechanical testing of the cancellous screws, the "ground truth" is established by adherence to recognized ASTM standards (ASTM F543) and engineering principles. For biocompatibility, the ground truth is adherence to ISO 10993-1. This is not related to clinical outcomes or expert consensus on pathologies for AI model training.

8. The sample size for the training set

Not applicable. This device is a mechanical shoulder replacement system, not an AI/machine learning device that requires a training set.

9. How the ground truth for the training set was established

Not applicable. This device is a mechanical shoulder replacement system, not an AI/machine learning device.


Summary of what is present:

The document describes the submission of a medical device (AGILON® XO Shoulder Replacement System) for regulatory clearance. The specific focus of this submission (K241944) is the addition of new cancellous screws to an existing system. The performance testing for these screws involved:

  • Engineering analysis.
  • Characterization per ASTM F543 for torsional properties, driving torque, and axial pull-out strength.
  • Biocompatibility evaluation per ISO 10993-1.
  • Leveraging existing data for cleaning, sterilization, packaging, shelf-life, and endotoxin from the predicate device (K231657).

The conclusion is that the testing demonstrated "sufficient performance for the intended use" and "met the predetermined acceptance criteria." However, the specific quantitative values for these criteria and the test results are not detailed in the provided text.
