Hemi or Total Arthroplasty Application of the Anatomical Shoulder Humeral Stems and Domelock System
The Anatomical Shoulder Humeral Stems and Domelock System are indicated for

• · Advanced wear and tear of the shoulder joint resulting from degenerative, posttraumatic or rheumatoid arthritis.
• · Avascular necrosis.
• · Conditions consequent to earlier operations.
• · Omarthrosis.
• · Rheumatoid arthritis.
• · Revision of shoulder prosthesis.

The Humeral Stems Cemented are intented for cemented use and the Humeral Stems Uncemented are intended for uncemented use. When used in a total shoulder application, the Anatomical Shoulder Pegged and Keeled Glenoids Cemented and the Biomet all-polyethylene Keeled Glenoid are intented use only. The Biomet Modular Hybrid Glenoid is intended to be implanted with bone cement. The optional porous titanium peg may be inserted without bone cement. The optional polyethylene peg should be inserted with bone cement.

Reverse Application of the Anatomical Shoulder System
· The Anatomical Shoulder Inverse/Reverse System is indicated for primary, fracture or revision total shoulder replacement for the relief of pain and significant disability due to gross rotator cuff deficiency.
· The patient's joint must be anatomically suited to receive the selected implants and a functional deltoid muscle is necessary to use the device.

The Humeral Stems Cemented are intended for cemented use and the Humeral Stems Uncemented are intended for uncemented use. When used with the Anatomical Shoulder Glenoid Fixation, it is intended for uncemented use and requires two screws for fixation.

Fracture Application of the Anatomical Shoulder Fracture System
The Anatomical Shoulder Fracture System is intended for use in prosthetic replacement of the glenoid articular surface of the scapula during total-, hemi and fracture shoulder arthroplasts in treatment of the following:

• · Complex 3- and 4-part fractures of the proximal humerus with subluxation of the head fragment
• · Complex 3- and 4-part fractures of the proximal humerus with loosening of the spongiosa in the head fragment
• · Complex 3- and 4-part fractures of the proximal humerus with additional cross split of the head fragment
• Fracture instability after osteosynthesis of 3- and 4-part fragments of the proximal humerus
• · Posttraumatic necrosis of the humeral head
• · Posttraumatic arthrosis after humeral head fracture

The Humeral Fracture Stems are intended for either cemented use. When used in a total shoulder application, the Anatomical Shoulder Pegged and Keeled Glenoids Cemented are intended for cemented use only.

The Anatomical Shoulder System is a modular shoulder prosthesis designed to be used in primary or revision, total or hemi shoulder arthroplasty.

Anatomical Shoulder Humeral Stems are available as either cemented or uncemented designs. Cemented stems are available in longer designs to support revision cases. The Anatomical Shoulder Fracture Stem is available as a slim and standard version, with longer stems available for revision surgery. They may be used with or without bone cement where appropriate fixation using cement or via a press-fit is achieved using the correct choice of rasp size. All Humeral Stems possess a female oval taper geometry, which is the basis for all modularity with compatible mating components. The stems can be combined with the Anatomical Shoulder Domelock Head or the Anatomical Shoulder Ball-taper Humeral Head. The assembled humeral component may be used alone for hemiarthroplasty or combined with the glenoid component of the Anatomical Shoulder System for total arthroplasty. Alternatively, the Legacy Biomet Bio-Modular Keeled all-polyethylene Glenoid or Modular Hybrid Glenoids are proposed as compatible glenoid components.

The Anatomical Shoulder System is intended for long-term implantation into the human shoulder joint in primary or revision, total or hemi shoulder arthroplasty. The system is intended to relieve pain and restore function in patients with adequate bone stock to support the prosthesis.

The provided document is a 510(k) premarket notification from Zimmer GmbH to the FDA for the Anatomical Shoulder™ System, Anatomical Shoulder Domelock® System, and Anatomical Shoulder™ Fracture System.

It describes the device and its intended use, but it does NOT describe an AI/ML-based medical device performance study, nor does it contain information about acceptance criteria or performance against such criteria for an AI/ML device.

The document states:
"The devices are not modified as compared to their predicates. Instead, the compatibility of the Anatomical Shoulder Humeral Heads is extended to allow articulation against the legally marketed Bio-Modular Keeled all-polyethylene Glenoid and the Modular Hybrid Glenoid. The indications for use/intended use are unchanged. The articulating materials remain the same with the new compatibility and therefore the fundamental technology is unchanged."

And for Performance Data:
"The results of non-clinical performance testing and analyses demonstrate that the devices are safe and effective and substantially equivalent to the predicate devices. Performance analyses included:

1. Range of Motion Analysis (ASTM F1378-12)
2. Radial Mismatch Analysis
   Clinical Performance and Conclusions: Clinical data and conclusions were not needed to demonstrate substantial equivalence."

Therefore, I cannot answer your specific questions regarding acceptance criteria for an AI/ML device and its study, as the provided text pertains to a traditional orthopedic implant (shoulder prosthesis) and not an AI/ML-based medical device.
