Intended Use

Bonelogic software is intended to be used by specialized medical practitioners to assist in the characterization of human anatomy with 3D visualization and specific measurements. The medical image modalities intended to be used in the software are computed tomography (CT) images, cone beam computed tomography (CBCT) images and weight-bearing cone beam CT (WBCT) images. The intended patient population is adults over 16 years of age. Bonelogic software contains the measurement template with a set of distance and angular measurements can be used for diagnostic purposes. The three dimensional (3D) models are displayed and can be manipulated in the software. Together, the information from the measurements and the 3D visualization can be used for treatment planning in the field of orthopedics (foot and ankle, and hand wrist). The 3D models can be outputted from the software for traditional or additive manufacturing. The physical models generated based on the 3D digital models are not intended for diagnostic use.

Device Story

Bonelogic is a software tool for specialized medical practitioners to process CT, CBCT, and WBCT images. It imports DICOM data; segments anatomy using semi-automatic or fully automatic algorithms; generates 3D models; and performs distance/angular measurements. Used in clinical settings for orthopedic treatment planning (foot, ankle, hand, wrist). Output includes 3D models for traditional or additive manufacturing and measurement data. Clinicians use visualizations and measurements to assist in diagnosis and surgical planning. Benefits include improved anatomical characterization and pre-surgical planning capabilities.

Clinical Evidence

### Comparison of Technological Characteristics with the Predicate Device

The subject device Bonelogic employs similar fundamental technologies as the predicate device.

Technological similarities include:

- Device functionality:
- Image segmentation: The subject and predicate device share the same image segmentation functionalities.
- Processing to output file: The subject and predicate device both generate an output file.
- Measuring and planning: The subject and predicate device both have functionalities to perform measurements and pre-surgical planning.

The following technological differences exist between the subject device and the predicate device:

- . lmaging information:
- Whereas the predicate device is more generally intended to import imaging information of a medical scanner, allowing both DICOM compatible images and standard imaging formats (such as RAW, TIFF, BMP and JPEG), the subject device is intended to import only DICOM compliant types.
- Device functionalities: ●
- Whereas the predicate device is creating Python scripts to automate workflows, the subject device is not supporting Python scripts.
- Device design:
- The design of the predicate device is organized in a toolbox fashion with manual steps in tissue segmentation and manual measurement tools, whereas the interface of the subject device specifically guides the user through a few predefined steps for obtaining a 3D output file and defined measurements.

### Performance data

Software verification and validation were performed, and documentation was provided following the "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices". This includes:

- | Subject device comparison with predicate device by comparing the geometric accuracy of outputted 3D models
- । Subject device comparison with predicate device by comparing repeatability of manual measurements and measurements created with subject device on radiographical parameters
- । Verification for the subject device against defined requirements via performance testing and clinical validation
- Validation for the subject device against user needs via clinical validation on usability of 3D models in clinical setting

End-user validation, clinical validation, and performance testing were performed.

The geometric accuracy of 3D virtual models created in the subject device Bonelogic software was assessed against similar virtual models created with predicate device. The comparison was made with DICOM images containing foot and ankle anatomy.

The measurement accuracy in the subject device Bonelogic software was assessed by comparing manual measurements of radiographical parameters against same measurements created in subject device. The manual measurements were performed by clinicians. The data set in the study included DICOM images containing hand and wrist anatomy.

The verification and validation of the subject device against defined requirements and against user need, was done via performance testing on measurements repeatability and with clinical validation for the accuracy of the 3D virtual models against original DICOM imaging data.

In conclusion, all performance testing conducted demonstrated device performance and substantial equivalence to the predicate device.

#### Summary

A comparison of intended use and technological characteristics combined with performance data demonstrates that Bonelogic software is substantially equivalent to the predicate device Mimics Medical (K183105). Minor differences in intended use and technological characteristics exist, but performance data demonstrates that Bonelogic software is as safe and effective and performs as well as the predicate device.
