Indications for Use

NextAR Hip is intended to support the surgeon during Total Hip Arthroplasty (THA) procedures by providing navigational information during bone preparation and positioning of acetabular cup components in skeletally mature individuals during supine or lateral approaches. NextAR Hip is indicated for use with Medacta hip prosthesis as described in the implants’ instruction for use. NextAR Hip provides stereotaxic guidance in reference to a patient’s rigid anatomy as registered in CT based or imageless workflows. As an optional display, the smart glasses can be used auxiliary to the NextAR Hip to view the same information as presented by the NextAR Hip. NextAR Smart Glasses should not be relied upon solely and should always be used in conjunction with the primary computer display.

Device Story

NextAR Hip Platform is a computer-assisted surgical navigation system for Total Hip Arthroplasty. It utilizes an infrared tracking system to monitor spatial locations of markers attached to patient anatomy and surgical instruments. The system processes this data to provide real-time stereotaxic guidance for bone preparation and acetabular cup positioning. It supports both CT-based and imageless workflows. The platform consists of a control unit, tracking system, and optional smart glasses for auxiliary visualization. Used in the operating room by surgeons, the system displays navigational information on a primary monitor to assist in executing the surgical plan. By providing precise, real-time feedback on instrument orientation and implant placement, the device aims to improve surgical accuracy and patient outcomes. The system is used in conjunction with Medacta hip prostheses.

Clinical Evidence

No clinical studies were conducted. Evidence consists of bench testing, including software verification and validation, cadaveric quantitative testing to confirm equivalence to conventional instrumentation, and in vitro accuracy testing for leg length and lateral offset assessment algorithms.

Technological Characteristics

Stereotaxic navigation platform; infrared tracking system; active/passive markers; control unit; smart glasses; CT-based or imageless workflow support. Software-based guidance for bone preparation and implant positioning. Sterile tracking sensors. Power source and user interface consistent with predicate navigation systems.

Indications for Use

Indicated for skeletally mature individuals undergoing Total Hip Arthroplasty (THA) via supine or lateral approaches, using Medacta hip prostheses.

Dear Christopher Lussier:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

## IV. Device Description

The NextAR Hip Platform is a computer-assisted surgical navigation platform used to support the surgeon during implantation in hip replacement procedures providing information on bone preparation, instrument guidance, and implant positioning.

The NextAR Hip Platform consists of three components:

- NextAR hardware (composed of NextAR Control Unit, NextAR Tracking System and NextAR Smart Glasses);
- NextAR Hip Software; and
- NextAR Hip stereotaxic instruments.

The system operates on the common principle of stereotaxic technology in which markers are mounted on the bones and an infrared camera is used to monitor the spatial location of the target. Tracking sensor attached to the pelvis and surgical instruments enable the surgeon to register the position and orientation of the patient’s anatomy and instrumentation relative to preoperative data in real-time while performing the surgical procedure. The tracking system is provided sterile.

NextAR Hip Platform aids the surgeon in executing the surgical plan by visualizing all the information in real time in a screen monitor.

## V. Indications for Use

NextAR Hip is intended to support the surgeon during Total Hip Arthroplasty (THA) procedures by providing navigational information during bone preparation and positioning of acetabular cup components in skeletally mature individuals during supine or lateral approaches.

NextAR Hip is indicated for use with Medacta hip prosthesis as described in the implants’ instruction for use. NextAR Hip provides stereotaxic guidance in reference to a patient’s rigid anatomy as registered in CT based or imageless workflows.

As an optional display, the smart glasses can be used auxiliary to the NextAR Hip to view the same information as presented by the NextAR Hip. NextAR Smart Glasses should not be relied upon solely and should always be used in conjunction with the primary computer display.

## VI. Comparison of Technological Characteristics

The subject NextAR Hip Platform and the predicate devices (K243751, K191507) are substantially equivalent with respect to the following characteristics:

- Power source;
- User interface;
- Imaging modalities;
- Surgical workflow; and
- Registration and planning features.

The subject NextAR Hip Platform and the predicate devices (K243751, K191507) differ with respect to the following characteristics.

- Tracking system;
- Use of smart glasses; and
- Surgical guidance features.

## Discussion

The subject and predicate (K243751, K191507) devices have different tracking technology (active vs. passive markers) as well as the availability of head mounted display/smart glasses does not introduce any new safety and effectiveness question since these features are the same of the reference device (K250477).

The additional surgical guidance features provided by the subject device with respect to the predicate devices (K243751, K191507) are substantially equivalent as demonstrated by software verification and validation as well as performance testing.

The comparison of technological characteristics and performance data provided within the submission supports the substantial equivalence of the subject device with respect to the predicate devices.

## VII. Performance Data

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

### Non-Clinical Studies

- Software verification and validation
- Cadaver quantitative testing to demonstrate that the subject platform is equivalent to the conventional instrumentation as well as the subject instruments are adequate for their intended use
- In vitro accuracy test to verify Leg Length and Lateral Offset assessment algorithms

### Clinical Studies:

- No clinical studies were conducted.

## VIII. Conclusion

The information provided above supports that the subject device is substantially equivalent to the predicate devices.
