Intended Use

The ROSA® Shoulder System, for use with the ROSA® RECON platform, is indicated as a stereotaxic instrumentation system for Total Shoulder Arthroplasty (TSA) surgery. It is used to assist the surgeon in providing software-defined spatial boundaries for orientation and reference to identifiable anatomical structures for the accurate placement of the shoulder implant components. The robotic arm placement is performed relative to anatomical landmarks and bony anatomy as recorded using the system intraoperatively, and based on a three-dimensional representation of the bone structures determined pre-operatively using compatible CT based imaging technology. It includes a robotic arm, an optical sensor navigation system and accessories, software system, surgical instruments and accessories.

Device Story

ROSA Shoulder System is a stereotaxic instrumentation system for Total Shoulder Arthroplasty (TSA). It utilizes the ROSA RECON platform, incorporating a robotic arm, optical sensor navigation, and software. Pre-operative CT-based 3D bone models are uploaded via the Zimmer Biomet Portal. Intraoperatively, the system registers patient anatomy; the surgeon uses the robotic arm to guide humeral resection and glenoid reaming. The system provides software-defined spatial boundaries for implant component placement relative to anatomical landmarks. Used in clinical settings by surgeons, the device assists in reproducing pre-operative plans, aiming for accurate implant positioning and improved surgical outcomes.

Clinical Evidence

No clinical data provided. Evidence consists of bench testing, engineering analysis, usability engineering, and a validation lab study using cadaveric specimens to simulate full surgical use. Biocompatibility testing followed ISO 10993. Electrical safety and EMC testing confirmed compliance with IEC 60601-1, IEC 60601-1-2, and IEC 60601-1-6.

Technological Characteristics

Stereotaxic instrumentation system comprising a robotic arm, optical navigation, and software. Connectivity via Zimmer Biomet Portal (MDDS). Complies with IEC 60601-1, IEC 60601-1-2, and IEC 60601-1-6. Software follows IEC 62304 standards. System uses optical tracking for real-time instrument guidance relative to CT-derived anatomical landmarks.

Indications for Use

Indicated for skeletally mature patients undergoing Total Shoulder Arthroplasty (TSA) using compatible humerus and glenoid implants. Contraindicated for patients with significant bone loss, severe range of motion limitations, active shoulder joint infections, or those requiring revision surgery. Also contraindicated if strong infrared sources/reflectors are present or if pre-existing radio-opaque elements interfere with imaging/registration.

| Purpose and Device Description: | The ROSA® Shoulder system (RSS) for use with ROSA® RECON Platform (cleared via K230243) is used to assist surgeons in performing Total Shoulder Arthroplasty (TSA) for both anatomic and reverse techniques. It features humeral resection and glenoid reaming capabilities to reproduce the preoperative plan intraoperatively with | | | | | | | | | | | | | | | |

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

| | The RSS uses a Non-Device Medical Device Data System (MDDS)<br>called the Zimmer Biomet Portal, which manages the creation and<br>tracking of surgical cases. The cases with the pre-operative planning<br>based on surgeon preferences reside on the portal until they are<br>uploaded to the ROSA RECON Platform before surgeries.<br><br>The intra-operative workflow and surgical concepts implemented in<br>the system remain close to the conventional TSA workflow. As such,<br>at the time of the surgery, the system mainly assists the surgeon in (1)<br>determining reference alignment axes in relation to anatomical<br>landmarks, (2) planning the orthopedic implants location intra-<br>operatively based on these reference alignment axes and orthopedic<br>implant geometry, and (3) precisely position the humeral cut guide and<br>glenoid reamer relative to the planned orthopedic implant location by<br>using a robotic arm. |

| Summary of<br>Technological<br>Characteristics: | The rationale for substantial equivalence is based on consideration of<br>the following characteristics:<br>• Indications for Use/Intended Use: The proposed device has the<br>same intended use and similar indications for use as the<br>predicates. The devices are intended to assist surgeons by<br>providing software-defined spatial boundaries for orientation, and<br>reference information to relative anatomical structures for<br>accurate implant component placement.<br>• The proposed and the predicates allow users for patient bone<br>registration within the software and use it to guide instruments<br>intra-operatively in real time using similar navigation system.<br>• The proposed and ROSA predicate device share the same<br>previously cleared ROSA RECON Platform with its major core<br>hardware and software components, tracking system, various<br>instrumentation including reusable and disposable. The proposed<br>and ROSA predicate use the robotic arm on the ROSA RECON<br>Platform to assist the guidance of instruments.<br>• The proposed and primary predicate assist surgeon using similar<br>intra-operative instruments guiding to perform the glenoid<br>reaming based on the surgeon's plan. |

The evaluation shows that<br>the ROSA Shoulder devices meets biocompatibility requirements.<br>Electromagnetic Compatibility (EMC) and Electrical Safety |
| Substantial Equivalence Conclusion: | Both the proposed device and predicate devices have the same intended use and similar indications for use and are used to guide instrumentation to assist with orthopedic surgery. The technological characteristics between the proposed device and the primary predicate are similar with bone registration and intra-operatively instrument guidance with live tracking. The proposed device does not perform any pre-operative surgical planning as is the case with primary predicate. The proposed ROSA Shoulder System and the secondary ROSA predicate utilize the same ROSA RECON Platform with its core hardware and software components. In addition, the proposed device and ROSA predicate use the robotic arm to assist the guidance of instruments. In summary, any differences between the devices do not raise new questions of safety and effectiveness and verification and validation |
