## 2.4 Device Description @
The brAIn™ Shoulder Positioning software is a cloud-based application intended for shoulder surgeons. It is used to plan primary anatomic and reverse total shoulder replacement surgeries using FX Shoulder Solutions implants. The software is a webbased interface, where the user is prompted to upload their patient's shoulder CT-scan (DICOM series) accompanied with their information in a dedicated interface. The software automatically segments (using machine learning) and performs measurements on the scapula and humerus anatomy contained in the DICOM series. These segmentations are used for planning, which includes an interactive 3D viewer that allows for soft tissue visualization. Implants for the glenoid and humerus are positioned using this same 3D interface through a dedicated manipulation panel. The changes in shoulder anatomy resultant from the implants are relayed in a post-position interface that displays information related to distalization. The software outputs a planning multimodal summary that includes textual information (patient information, pre- and post-op measurements) and visual information (screen captures of the shoulder pre- and postimplantation).

The performance of brAln™ Shoulder Positioning was validated by nonclinical testing met the acceptance criteria (passed), demonstrating that the software fulfills its requirement specifications.
# 2.7 Predicate Device Comparison
The subject device and the primary device have similar indications for use in that they are both intended to use CT-scan imaging and the intended type of implants and duration of use are also similar.
The brAIn™ Shoulder Positioning has minor differences from the predicate device.
Internal verification and validation testing confications are met which are equivalent in design and technological characteristics as the predicate device. The testing results support that the Software validation of the acceptance of the device. brAIn™ Shoulder Positioning passed all testing and supports the claims of substantial equivalence to the predicate device.
Overall, these differences do not raise new questions of safety or effectiveness and therefore is substantially equivalent to the predicate device.
# 2.8 Performance Data ✆
Software Verification and Validation Tests:
{8}------------------------------------------------
Safety and performance of the brAIn™ Shoulder Positioning has been evaluated and verified in accordance with software specifications and applicable performance standards through software verification testing. The model was evaluated taking into account applicable requirements of the FD&C Act and 2081 implementing regulations.
Additionally, the software validation activities were performed in accordance with ANSI AAMI IEC 62304:2006/A1:2016 - Medical device software – Software life cycle processes, in addition to the FDA Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices" and "Content of Premarket Submission for Cybersecurity in Medical Devices."
#### Segmentation Performance Testing:
The brAIn™ system's automatic segmentation was validated against manual segmentation, meeting a mean Dice Similarity Coefficient (DSC) on the testing set greater than or equal to 0.95. All tests confirmed that the segmentation performance meets the acceptance criteria, ensuring compliance.
The automatic segmentation provided by brAIn™ Shoulder Positioning was validated against manual segmentation performed. The validation criterion was a Dice Similarity Coefficient of 0.95 or higher, demonstrating that the segmentation produced by the model after post-processing closely matches the ground truth.
The dataset is comprised of 508 pairs of 3D images (DICOM series) together with their segmentation labels. The 3D images have on average 467 (axial) slices of resolution 512x512 pixels.
The dataset is divided into two partitions:
- Training Set (65.9%, 335 samples)
- · Shoulder Side: 43.3% left (145), 56.7% right (190)
- o Gender: 57.9% female (84), 41.4% male (60), 0.7% unspecified (1) for left; 57.4% female (109), 42.1% male (80), 0.5% unspecified (1) for right
- Geographical Origin: 46.9% Europe (68), 56.4% USA (77) for left; 52.6% Europe (100), 47.4% USA (90) for right
- · Testing Set (34.1%. 173 samples)
- · Shoulder Side: 45.7% left (79), 54.4% right (94)
- · Gender: 55.7% female (44), 44.3% male (35) for left; 63.8% female (60), 36.2% male (34) for right
- · Geographical Origin: 58.2% Europe (46), 41.8% USA (33) for left; 56.4% Europe (53), 43.6% USA (41) for right
The data corresponds to patients that under arthroplasty with an FX Shoulder implant without any further specific selection, representing a diversity in shoulder, imaging equipment, institutions, study year and geographical provenance. The protocol used for image acquisition is standard for patient undergoing a total shoulder arthroplasty.
The labels were created manually by medical professionals.
To prevent any form of data leakage, we took the following precautions: first, the training and testing datasets were split at the patient level to ensure that no patient data was included in both sets. Second, to ensure both of the dataset, we performed a stratified split based on patient gender, shoulder side and geographical region of origin. With this approach, we ensure that both sets accurately reflect the intended patient population. Besided to boost the representation of study collected in 2024 in the testing dataset compared to the training dataset, enabling thus a better generalization on future images and increased independence between datasets.
#### Shoulder Side Detection performance testing:
Validation compared the correct shoulder side (right or left) in DICOM images to a manual assessment performed by a Clinical Solutions Specialist. All performance tests for Shoudler Side Detection validation were successfully completed with no deviations, confirming compliance with the required performance standards.
{9}------------------------------------------------
#### Measurement Accuracy_performance testing:
Validation compared the accuracy of the brAln™ Shoulder Positioning software measurement when editing the position of landmarks within the software to to the reported accuracy of the predicate. All performance tests for Measurement Accuracy Validation were successfully completed with no deviations, confirming compliance with the required performance standards.
#### Landmark Performance Testing:
Validation compared pre-positioning with final positions adjusted by experts, achieving accuracy similar to manual positioning with a 3 mm mean distance as the acceptance criterion. All performance tests for landmark validation were successfully completed with no deviations, confirming compliance with the required performance standards.
## 2.9 Statement of Substantial Equivalence &
The brAln™ Shoulder Positioning is as safe and effective as the predicate device. The brAln™ Shoulder Positioning has the same intended uses and similar indications, technological characteristics, and principles of operation as its predicate device.
The minor technological differences between the brAn™ Shoulder Positioning and its predicate device raise no new issues of safety or effectiveness. The performance data demonstrates that the brAIn™ Shoulder Positioning is as safe and effective as the predicate device.
By definition, a device is substantially equivalent to a predicate device has the same intended use and the same technological characteristics as the previously cleared predicate device has the same intended use and different technological characteristics that can be demonstrated that the device is substantially equivalent to the new device does not raise additional questions regarding its safety and effectiveness as compared to the predicate device.
brAIn™ Shoulder Positioning, as designed and manufactured, is determined to be substantially equivalent to the referenced predicate device.
