RI.HIP MODELER is intended for preoperative planning for primary Total Hip Arthroplasty. RI.HIP MODELER is intended to be used as a tool to assist the surgeon in the selection and positioning of components in primary Total Hip Arthroplasty. RI.HIP MODELER is indicated for individuals undergoing primary Total Hip Arthroplasty.
The indication is substantially equivalent to the indications for use of the predicate, hipEOS (K173390), which is also indicated as a tool to assist healthcare professionals in preoperative planning for Total Hip Arthroplasty. The tools that are included in the predicate device's indications are substantially equivalent to the subject device and compared in the technological characteristic section of the substantial equivalence discussion.
²Image Format
DICOM images downloaded from Quentry are displayed as a PNG file. RI.HIP MODELER also allows the user to take a picture of an x-ray with the iPad which displays as a PNG file or pull a picture from the camera roll. The software was designed to autodetect and dewarp (if necessary) the specified x-ray. Images can be enhanced using contrast and brightness filters. Additionally, they can be cropped, reset, and retaken. Verification confirmed the camera functionality generated a clinically relevant image with minimal distortion even in worstcase scenario conditions. Training is provided to surgeons on the use of the camera in the application. Human Factors validation confirmed that users could successfully use the camera function to obtain a clinically acceptable image. Validation further showed that those images could be successfully landmarked. The use of the iPad camera to capture an x-ray image does not raise new questions of safety or effectiveness for RI.HIP MODELER.
3 Primary Device Function
RI.HIP MODELER is substantially equivalent to hipEOS in primary function. hipEOS provides a recommendation for both stem and cup placement in the hip. RI.HIP MODELER provides a baseline cup orientation recommendation. The cup recommendation is a subset of the functionality and does not raise new questions of safety or effectiveness for RI.HIP MODELER. Like hipEOS, RI.HIP MODELER uses spinopelvic mobility of the patient to recommend cup inclination/anteversion. hipEOS derives stem torsion based on the 3D model of the patient's anatomy. RI.HIP MODELER allows the user to input stem anteversion based on clinical judgment. Both applications allow the user to adjust stem anteversion. The difference does not raise new questions of safety or effectiveness as the stem torsion is ultimately identified by the qualified healthcare professional.
4Principles of Operation
RI.HIP MODELER is substantially equivalent to hipEOS in principles of operation. Both devices use standing and sitting x-rays to ascertain the spinopelvic mobility of the patient.
6
hipEOS reconstructs the patient's anatomy in 3D using frontal and lateral 2D x-rays. The 3D model shows torsion and rotation parameters based on the patient's anatomy. The software provides a baseline stem and cup orientation based on the spinopelvic mobility classification derived from the 3D model and implant specifications.
RI.HIP MODELER employs an algorithm using the determined spinopelvic mobility classification and hip kinematics for typical patient activities of daily living (accessed through a simulation database). Implant kinematics and distance to impingement are calculated for each activity, given a set of implant specifications. The software provides a baseline cup orientation recommendation based on the spinopelvic mobility classification and implant specifications.
The computational models used in the design of RI.HIP MODELER comply with ASME V&V 40: 2018, Assessing Credibility of Computational Modeling through Verification and Validation; Application to Medical Devices and support the algorithm that provides the baseline cup orientation. There are no new questions of safety or effectiveness in using the RI.HIP MODELER to provide a baseline cup orientation as the computational models that support the design have been verified and validated.
§Technological Characteristics
There are no new concerns for safety or effectiveness associated with the technological characteristics of RI.HIP MODELER.
- . RI.HIP MODELER and hipEOS are both standalone software applications with an interactive design that allows the user to overlay 2D x-rays with virtual measuring tools to derive a spinopelvic mobility classification of the patient.
- hipEOS uses a frontal and lateral x-ray to develop a 3D model of the patient's hip. RI. HIP MODELER displays a simulated 3D model of the hip based on the spinopelvic mobility classification. The simulated model is derived from validated computational models that effectively display the range of implant motion in the model.
- The 3D models in both RI.HIP MODELER and hipEOS allow the user to select and overlay implants and view a simulated range of motion.
- . RI.HIP MODELER and hipEOS both provide a range of implant motion simulation that allows the surgeon to see how the implant moves in the hip.
- RI.HIP MODELER recommends an acetabular cup placement based on spinopelvic mobility classification. The surgeon selects and compares implants from an application database. hipEOS automatically selects and positions the stem and cup based on 3D reconstruction of the patient anatomy. The surgeon can select and compare the stem and cup from an online database.
- . The user can change the inclination/anteversion and stem torsion within the app and visualize the effect of those changes on the 3D model.
- RI.HIP MODELER uses computational modeling in its design that allows a surgeon to view distance to implant impingement through a variety of daily activities of the patient, including, but not limited to, sitting, standing, and walking. hipEOS uses a 3D reconstruction that allows a surgeon to plan implant placement for sitting, standing, and theoretical sitting positions.
7
- . RI.HIP MODELER is an iPad application and hipEOS is a web application. Both devices are standalone software.
There are no new concerns for safety or effectiveness due to the difference in technological characteristics because RI.HIP MODELER was designed to meet its intended use with the technological characteristics within the app. Verification and Validation from Performance Testing confirms that the RI.HIP MODELER is safe and effective and meets its intended use. Performance Testing confirms that representative users of the software application were able to successfully follow the workflow and use the software application in a safe and effective way in the intended use environment.
َ User Interface
RI.HIP MODELER is standalone software that is intended to be installed on an iPad. The predicate device is standalone software that can be installed on any computer. The subject software was verified and validated to ensure specifications were met. User validation showedsurgeons can use the RI.HIP MODELER application safely and effectively on an iPad to plan for total hip arthroplasty procedures. There are no new questions of safety or effectiveness due tothe different interface as the design of RI.HIP MODELER was specific to the intended interface and allows the device to perform its intended use.
Non-Clinical Testing (Bench)
Design verification and validation testing was performed to demonstrate that RI.HIP MODELER meets all design requirements and is as safe and effective as its predicate device. Comprehensive performance testing demonstrated that the subject devices meets the required design inputs. Performance data consisted of physical performance test for all the software application. Additionally, the following test data was provided:
- . Software Verification Testing, including software integration and workflow testing, was completed. Software was developed in accordance with IEC 62304 Medical Device Software -Software Life Cycle Processes, and this submission contains documentation per the requirements of FDA's Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices.
- Image Capture Verification Testing was completed to ensure worst case image capture would not produce distorted images that would affect clinical measurements. Testing demonstrated that even in worst-case conditions accuracy of landmarking measurements was within 2 degrees.
- Usability Engineering Validation Testing was completed demonstrating that representative users were able to safely and effectively use RI.HIP MODELER in a simulated use environment.
No human clinical testing was required to determine the safety and effectiveness of RI.HIP MODELER.

Conclusion
The subject device, RI.HIP MODELER, described in this submission has a similar intended use and primary device function as the predicate device, hipEOS (K173390). The primary difference between the two devices is that RI.HIP MODELER uses 2D x-rays and an algorithm based on computational modeling to determine a baseline acetabular cup placement while hipEOS uses a 3D model of the patient derived from a compilation of x-rays to determine stem and cup placement. The differences do not raise any new questions of safety or effectiveness.
The key determining factor in establishing substantial equivalence is whether RI.HIP MODELER can provide a baseline cup orientation that increases distance to implant impingement during activities of daily living, thereby reducing the risk of implant impingement. The results of verification and validation indicate that there are no safety or performance concerns and that RI.HIP MODELER meets its intended use. The usability testing results for Human Factors demonstrate that representative users are able to use the subject device safely and effectively to meet the desired intended use. The information presented in this 510(k) premarket notification demonstrates that RI.HIP MODELER is as safe and effective as the predicate hipEOS system (K173380). Blue Belt Technologies believes that RI.HIP MODELER is substantially equivalent to the predicate device.
