No
This device is a surgical assistance system that helps surgeons accurately place hip implant components during total hip arthroplasty. It does not directly treat a disease or condition.
No
Justification: The ROSA® Hip System is described as a surgical assistance system for total hip arthroplasty (THA), providing spatial boundaries, orientation, and reference information for accurate implant placement. It assists surgeons in performing procedures, but it does not make a diagnosis of a disease or condition itself. Its function is to facilitate the surgical process, not to identify a medical condition.
No
The device description explicitly states that the system utilizes the robotic arm of the ROSA® RECON platform (cleared in K182964) and uses fluoroscopic images acquired with a C-arm. It also mentions the ROSA® Tablet. These are hardware components integral to the device's function.
Based on the provided information, the ROSA® Hip System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- ROSA® Hip System Function: The ROSA® Hip System is a surgical guidance system used during surgery (in vivo) to assist the surgeon in placing hip implant components. It uses fluoroscopic images of the patient's anatomy and provides spatial guidance and measurements. It does not analyze biological specimens.
Therefore, the ROSA® Hip System falls under the category of a surgical guidance or navigation system, not an In Vitro Diagnostic device.

Device Description
The ROSA® Hip System (RHS) for use with the ROSA® RECON platform is used to assist surgeons in performing Total Hip Arthroplasty (THA) with features to assist in acetabular shell impaction for the direct anterior approach, as well as assessing the leg length discrepancy and the femoral offset.
The ROSA® Hip System uses a Non-Device Medical Device Data System (MDDS) called the Zimmer Biomet Drive Portal, which manages the creation and tracking of surgical cases. The cases reside on the portal until they are uploaded to the ROSA® RECON Platform before surgeries. The ROSA® Hip System utilizes the robotic arm of the ROSA® RECON platform cleared in K182964, but does not add new stereotaxic or robotic components
The system uses fluoroscopic images to determine the instruments' orientation in relation to the patient anatomy and as a guide for acetabular component orientation. The system allows the surgeon to input the case's surgical preoperative planning values and preview the acetabular component orientation intra-operatively. Throughout the surgical workflow, fluoroscopic images are acquired with a C-arm. Fluoroscopic images are then captured with the ROSA® Tablet and transferred onto ROSA®. The current instruments' orientation is computed from the image capture and is adjusted to match the surgeon's planning values using the ROSA® RECON robotic arm. The system provides pre, intra and post-operative measurements relative to patient anatomy and does not provide infrared-based stereotaxic navigation for implant placement. The robotic arm is maintained stationary to keep the instruments in a fixed orientation during acetabular component impaction. The system also provides component selection options based on leg length and offset discrepancies measurements.
The intra-operative workflow and surgical concepts implemented in the system remain close to the conventional THA direct anterior approach workflow. As such, at the time of the surgery, the system mainly assists the surgeon in (1) determining reference alignment axes and cup orientation using image-to-image and robotic registration, (2) precisely orienting the cup inserter relative to the desired orthopedic implant angle by using a robotic arm, and (3) providing leg length and offset discrepancies measurements based on fluoroscopic image references.
