The hardware: The Aequalis Glenoid Guides are patient-specific drill guides. They have been specially designed to assist in the intraoperative positioning of glenoid components used with total anatomic shoulder arthroplasty procedures using anatomic landmarks that are identifiable on patient-specific preoperative CT-scans. Aequalis PerFORM Anatomic Glenoid Guide is used by surgeons to facilitate the placement of the Aequalis PerFORM glenoids and the Aequalis PerFORM + glenoids.

The software: The BLUEPRINT 3D planning software is a medical device for surgeon composed of one software component. It is intended to be used as a pre-surgical planner for shoulder orthopedic surgery. BLUEPRINT 3D planning software runs on standard personal and business computers running Microsoft Windows or Mac OS operating systems. The software supports DICOM standard to import the CT-Scan (Computed Tomography) images of the patient. Only CT-Scan modality can be loaded with BLUEPRINT3D planning software. BLUEPRINT 3D planning software allows surgeon to visualize, measure, reconstruct, and annotate anatomic data. It allows surgeon to design patient specific guides based on the presurgical plan. This device is intended for use provided anatomic reference points necessary for positioning of the guide are present on the CT scan. The software leads to the generation of a surgery report along with a 3D file of the patient-specific guide. BLUEPRINT 3D planning software does not include any system to manufacture the guide. BLUEPRINT 3D planning software is to be used for adult patients only and should not be used for Diagnostic purpose.

BLUEPRINT™ Patient Specific Instrumentation is composed of two components: Aequalis Glenoid Guides (hardware) and BLUEPRINT 3D planning software (software). BLUEPRINT™ Patient Specific Instrumentation which includes the Aequalis Glenoid Guides and BLUEPRINT 3D planning software is the responsibility of Tornier is the legal manufacturer for the hardware and the software.

The hardware: The Aequalis Glenoid Guides are patient-specific instruments specially designed to facilitate the implantation of the Aequalis PerFORM shoulder prostheses and the Aequalis PerFORM + shoulder prostheses. The Aequalis Glenoid Guides are designed and manufactured based on a pre-operative plan generated only by the software BLUEPRINT™ 3D planning software.

The software: BluePrint 3D Planning software is composed of one software component connected to an Online Management System (OMS). The software installed on a computer is intended to be used by orthopedic surgeons, as a preoperative planning software for shoulder arthroplasty surgery (= total anatomic shoulder replacement). It is intended to help -plan an operation by allowing surgeons to: - position and select the glenoid implant, - design a patient specific pin guide.

Here's a breakdown of the acceptance criteria and the study that proves the device meets them, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state the sample size used for the test set in the "Compare post-operative clinical data with pre-operative plans" study. It also does not specify the country of origin of the data or whether it was retrospective or prospective.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

The document does not specify the number of experts used or their qualifications for establishing ground truth.

4. Adjudication Method for the Test Set

The document does not describe the adjudication method used for the test set.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

The document does not indicate that a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was done. The studies mentioned focus on the device's compatibility and accuracy rather than comparing human reader performance with and without AI assistance.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

The document describes the "BLUEPRINT 3D planning software" as a "medical device for surgeon composed of one software component" intended to "assist in pre-operative surgical planning." This implies a human-in-the-loop scenario, where the software assists the surgeon. The study to "Perform tests of software features when the Aequalis PerFORM+ is selected" verifies the software's functionality and display, which seems to be a standalone test of the algorithm's output within the software environment. However, it's not a standalone performance study in the sense of the algorithm diagnosing or acting without human interpretation or intervention for clinical outcomes.

The "Compare post-operative clinical data with pre-operative plans" study indirectly assesses the software's effectiveness when used by surgeons, but it's still about the overall patient-specific solution, including the guide.

7. The Type of Ground Truth Used

For the study "Compare post-operative clinical data with pre-operative plans to verify the accuracy of the patient-specific solution in Aequalis PerFORM+ configuration", the ground truth is derived from post-operative clinical data, specifically assessing the "correct positioning of the main pin." This suggests an objective measurement from actual surgical outcomes.

For the other two validation methods, "technical, biological, and clinical equivalences" and "no dysfunction of the software features," the ground truth would be based on predefined technical specifications, biological assessments, and functional requirements of the software, as well as presumably expert review of the software's output.

8. The Sample Size for the Training Set

The document does not provide information on the sample size used for the training set for the BLUEPRINT 3D planning software.

9. How the Ground Truth for the Training Set Was Established

The document does not provide information on how the ground truth for the training set was established. Since it is pre-surgical planning software, it's possible that historical CT-scans and corresponding surgical outcomes or expert annotations were used, but this is not specified.
