Intended Use

The MyHip Planner software is intended for image processing and preoperative planning of acetabular cup and femoral stem positioning for Total Hip Arthroplasty (THA). The user is assisted in producing a preoperative plan, making decisions based on the leg offsets, the patient's potential impingement and, optionally, the spino-pelvic interaction. Through the software, the user can request 3D Printed Patient Specific Bone Models not intended for diagnostic use, but only intended for a physical representation of the 3D anatomical models visualized in the software. The 3D Printed Patient Specific Bone Models are provided non-sterile.

Device Story

Advanced MyHip Planner is a software-based preoperative planning tool for Total Hip Arthroplasty (THA). It processes patient CT scans and X-ray images to generate 3D anatomical models. Surgeons use the software to plan acetabular cup and femoral stem positioning, evaluate leg length/offset, assess potential impingement, and analyze spino-pelvic mobility/deformities. The software provides an optional service to produce non-sterile 3D printed bone models as visual references. Operated by surgeons in a clinical setting, the software assists in optimizing implant orientation to improve THA stability. It runs on standard Windows or Mac OS PCs. The output informs surgical decision-making by providing a patient-specific plan and visual anatomical aids, potentially improving surgical outcomes by addressing patient-specific biomechanics.

Clinical Evidence

No clinical studies were conducted. Performance was established through non-clinical software verification and validation, including segmentation validation. Analysis of automatic segmentation and landmark picking performance showed no statistical divergence from manual segmentation using a two-sided student's t-distribution.

Technological Characteristics

Software-based medical image management and processing system. Compatible with Windows and Mac OS. Inputs: CT scans and X-rays. Features: Automatic segmentation (user-verified), 3D anatomical modeling, spino-pelvic evaluation, and optional 3D printing of bone models. Connectivity: Data transfer via hard disk (CD/USB) or wireless through MySolution website.

Indications for Use

Indicated for patients undergoing Total Hip Arthroplasty (THA) requiring preoperative planning of acetabular cup and femoral stem positioning, including assessment of leg offsets, potential impingement, and spino-pelvic interaction.

#### VI. Comparison of Technological Characteristics

{5}------------------------------------------------

| Parameters | Advanced MyHip Planner<br>(Subject device) | MyHip Planner<br>(Predicate device K200350) |
|---------------------------------------|-------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------|
| Input images<br>acquisition<br>method | X-rays Through hard disk (CD/USB) or wireless through MySolution website | Same |
| User interface | GUI | Same |
| Workflow | CT images upload Segmentation Planning including spino-pelvic evaluation Bone models production and shipping (optional) | CT images upload Segmentation Planning |
| Segmentation | Automatic but the user has to check, eventually modify, and confirm it | Same |
| Available<br>implants | Medacta hip implants cleared to FDA by Medacta | Same |
| Measurements<br>output | Cup positioning Stem positioning ROM evaluation Spino-pelvic evaluation | Cup positioning Stem positioning ROM evaluation |

The subject Advanced MyHip Planner and the predicate device are substantially equivalent with regards to the following characteristics:

- operative system compatibility;
- design concept/principle of operation;
- . user interface;
- images importation method;
- segmentation and landmark acquisition method; and
- . available implants.

The subject Advanced MyHip Planner differs from the predicate device with respect to:

- input images;
- workflow; and
- measurements output.

# Discussion

The slightly different input images and workflow of the subject device with respect to the predicate does not affect the safety and effectiveness of the Advanced MyHip Planner since it is only related to the addition of new input images (x-rays) and workflow steps strictly related to the newly developed feature allowing spino-pelvic evaluation and the manufacturing of bone models, both optional steps. Identically to the bone models included in the reference device clearance (K093806), the subject bone models are manufactured through the software starting from the patient's CT as an additional visual reference of the patients' specific anatomy, thus no new issue of safety and effectiveness arise.

{6}------------------------------------------------

Also measurements output differences are strictly related to the new spino-pelvic evaluation feature and does not raise any new issue of safety and effectiveness since the other output measurements are identical to the ones of the predicate device (K200350).

The comparison of technological characteristics and validation provided within this submission, supports the substantial equivalence of the subject devices respect to the predicate devices.

#### VII. Performance Data

Based on the risk analysis, verification activities were conducted to written protocols. The following software verification and validation are provided in support of the substantial equivalence determination:

# Non-Clinical Studies

- . Software verification and validation including segmentation validation. No statistical divergence between the algorithm and the manual segmentation has been revealed by an analysis of the automatic segmentation and landmark picking performance on a two-sided students t-distribution.
# Clinical Studies:

- No clinical studies were conducted. ●
#### Conclusion VIII.

The information provided above supports that the Advanced MyHip Planner is substantially equivalent to the predicate devices.
