No
The description focuses on stereotaxic technology, optical tracking, and real-time navigation based on preoperative CT data and instrument tracking. There is no mention of AI or ML algorithms for image analysis, planning, or guidance. The "registration algorithm" mentioned is a standard component of navigation systems and doesn't necessarily imply AI/ML.
No
The device is a computer-assisted surgical navigation platform and does not directly provide therapy. It assists the surgeon in performing glenoid implantation during shoulder replacement by providing real-time information and guidance.
No
The device is a computer-assisted surgical navigation platform that provides guidance and real-time information to the surgeon during a total shoulder arthroplasty, rather than providing a diagnosis of a patient's condition.
No
The device description explicitly lists multiple hardware components including a PC based hardware platform, optical tracking system, Augmented Reality glasses, and reusable surgical instruments, in addition to the navigation software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device "supports the surgeon during glenoid implantation in anatomic shoulder replacement procedures providing information on bone preparation, instrument guidance, and implant positioning." This describes a surgical navigation system used during a surgical procedure, not a test performed in vitro (outside the body) on biological samples to diagnose a condition.
- Device Description: The description details a "CT based computer-assisted surgical navigation platform" that uses optical tracking and software to guide surgical instruments in real-time. This aligns with surgical navigation technology, not IVD technology.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, tissue, etc.), detecting specific analytes, or providing diagnostic information about a patient's health status.
The device is a surgical navigation system designed to assist surgeons during a specific orthopedic procedure.

Intended Use / Indications for Use
The NextAR Shoulder™ Platform supports the surgeon during glenoid implantation in anatomic shoulder replacement procedures providing information on bone preparation, instrument guidance, and implant positioning.
The NextAR Shoulder™ Platform works in conjunction with NextAR™ stereotaxic instruments and general surgical instruments to implant the Medacta Shoulder System Anatomic (TSA - Total Shoulder Arthroplasty). As an optional display, the smart glasses can be used auxiliary to the NextAR Shoulder™ Platform to view the same 2D stereotaxic information as presented by the NextAR Shoulder™ Platform.
The NextAR Shoulder™ stereotaxic instruments are to support the surgeon during specific orthopedic surgical procedures by providing information on bone preparation, instrument guidance, and implant positioning. Once registered, the NextAR™ stereotaxic instruments provide reference to a patient's rigid anatomical structures on the surface of the glenoid that are identified relative to preoperative C.T. based planning.
The smart glasses should not be relied upon solely and should always be used in conjunction with the primary computer display.

Device Description
The Shoulder NextAR™ TSA Platform is a CT based computer-assisted surgical navigation platform used to perform a total shoulder arthroplasty on the glenoid and includes the following components:
- PC based hardware platform; (K210153)
- . optical tracking system: (K210153)
- . Augmented Reality glasses: (K210153)
- Platform (K210153) ●
- navigation software which displays information to the surgeon in real-time; ●
- Reusable surgical instruments to perform the surgical steps of a shoulder anatomic . arthroplasty on the glenoid.
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 markers. Tracking sensors attached to the scapula and surgical instruments enable the surgeon to register the position and orientation of scapula and instrumentation relative to preoperative data in real-time while performing the surgical procedure. The tracking sensors are provided sterile.
Shoulder NextAR™ TSA Platform aid the surgeon in executing the surgical plan by visualizing all the information in real time in a screen monitor.
The NextARTM TSA system is intended to assist the surgeon in executing a preoperative surgical planning. The navigation platform tracks the surgical instruments in real-time and displays intraoperative and planned surgical parameters on a screen, thus allowing the surgeon to match the intraoperative parameters with the planned ones.
Specifically, the navigation system utilizes established technologies of navigation and via an active infrared camera rigidly coupled with the scapula and an active infrared tracker that can be rigidly coupled to the surgical instruments. The registration of the patient's scapula on the preoperative scapula model is performed through the use of dedicated surgical instruments (pointers) and a dedicated registration algorithm.

For both NextAR™ RSA and NextAR™ TSA the registration algorithm has not changed but the glenoid registration is now completed with 6+20 points instead of 4+30 that was included in the previous version.
Discussion
There are minor differences between the subject and predicate devices;
Comparing the subject device to the main predicate NextAR™ RSA Platform K210153 the differences are the indication for use, software for navigation and dedicated instruments. They do not raise different questions of safety or effectiveness. Both navigation systems utilize stereotaxic technologies. Minor differences are addressed by performing cadaveric testing and rational.
VII. Performance Data
Testing was conducted according to written protocols with acceptance criteria that were based on standards. The following studies were performed in support of a substantial equivalence determination:
- software validation;
- cadaver study;
- rational on glenoid registration
The following studies were accepted during the submission of the predicates NextAR™ RSA K210153 and NextAR Spine K223769 and they are unchanged.
- biocompatibility per ISO 10993-1:2009;
- sterilization validation;
- shelf-life testing;
- electrical safety testing per IEC 60601-1:2005, COR1:2006, COR2:2007, Amd1:2012;
- electromagnetic compatibility testing per IEC 60601-1-2:2014;
- performance testing to evaluate mechanical and optical properties. ●

VIII. Conclusion
The information provided above supports that the Shoulder NextAR™ TSA Platform is substantially equivalent to the identified predicate devices. Substantial equivalence has been demonstrated through a comparison of intended use, design and technological characteristics, as well as performance evaluations. The Shoulder NextAR™ TSA Platform can be considered substantially equivalent to the identified predicate devices.
