Yes
The document explicitly states "The device uses machine learning derived outputs" and "The AI algorithm for bone identification was developed using...". It also mentions "AI/ML Testing" and describes the training and test sets used for the AI algorithm.
No
The device is described as a software tool for diagnosis and surgical planning, not for directly providing therapy or treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states that "The visualization report containing the measurements can be used for the diagnosis of orthopaedic healthcare conditions."
Yes
The device description explicitly states it is a "software tool" and the intended use and device description focus solely on software functionalities like visualization, measurement templates, and surgical planning based on input images. There is no mention of accompanying hardware components or hardware-specific verification/validation.
Based on the provided information, the SMART Bun-Yo-Matic X-Ray software is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body. The SMART Bun-Yo-Matic X-Ray software's input is X-ray images, which are generated by imaging the human body directly, not by analyzing a biological sample taken from the body (like blood, urine, tissue, etc.).
- The intended use is for diagnosis and surgical planning based on medical imaging. While the software aids in diagnosis by providing measurements and visualizations, this is done through the analysis of medical images, not through the analysis of in vitro specimens.
- The device description focuses on image processing and surgical planning. The core function is to process X-ray images, create 3D models, provide measurements, and facilitate surgical planning. This aligns with medical imaging software, not IVD devices.
In summary, the SMART Bun-Yo-Matic X-Ray software falls under the category of medical imaging software used for diagnosis and surgical planning, which is distinct from In Vitro Diagnostic devices.

The letter does not mention that the FDA has reviewed and approved or cleared a Predetermined Change Control Plan (PCCP) for this specific device. The provided text for "Control Plan Authorized (PCCP) and relevant text" explicitly states "Not Found".
Intended Use / Indications for Use
SMART Bun-Yo-Matic X-Ray software is to be used by orthopaedic healthcare professionals for diagnosis and surgical planning in a hospital or clinic environment. The medical imaging type intended to be used as the input of the software is X-ray.
The SMART Bun-Yo-Matic X-Ray software provides:
· Visualization report of the three-dimensional mathematical models of the anatomical structures of the foot and ankle and three-dimensional models of orthopaedic fixation devices.

Intended User / Care Setting
orthopaedic healthcare professionals in a hospital or clinic environment.
Description of the training set, sample size, data source, and annotation protocol
The AI algorithm for bone identification was developed using 1,5776 x-ray and CBCT DRR and metal identification was developed using 15 x-ray and CBCT DRR. The x-ray and CBCT DRR were collected from various sites across USA, Germany, UK, Finland, and Korea. The x-ray and CBCT DRR were collected from patients with different ages and racial groups, with minimum of 5% male/female within each dataset, with mean age approximately 35 years, and representatives from White (Non-)Hispanic, Hispanic, and Native American racial groups. Each dataset was balanced in terms of subjects with different foot alignment, demographics, imaging devices and with subjects from clinical subgroups ranging from control/normal feet to pre-/post-operative clinical conditions such as Hallux Valgus, and undefined indications.
Description of the test set, sample size, data source, and annotation protocol
Testing was carried out using 97 x-ray and DRR. Out of 97 image studies, 42 were from individual patients with some studies from same patient with different foot alignment or laterality. The 97-image x-ray and DRR test set was collected from five (5) different systems from five (5) different manufacturers. This set of five (5) imaging systems contained three (3) x-ray and two CBCT DRR machines. From the total test data 31% of the images were collected from a Siemens - Aristos and Ysio X-Pree X-ray system, 13% were collected from an iRAy Gamma X-ray system 1% were collected from a Swissray Medical AG ddR Element System X-ray system, 53% were collected from a Carestream OnSight 3D Extremity Scanner CBCT DRR, and 2% were collected from a CurveBeam PedCAT CBCT DRR.
The ground truth for the testing data was established by 2 (2) clinicians with over five (5) years of experience practicing medicine. Each clinician was given the same image data to review dorsoplantar and lateral x-ray images. Each clinician then marks on a spreadsheet the presence of the bone in the image.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance testing was conducted. Testing included the following:
AI/ML Testing.
Comparison of the 2D-3D construction to manual measurements as well as ground truth.
Comparison of the clinical acceptability of axes placement.
Comparison of the planned surgical correction to the actual surgical correction.
Results showed the subject device performed as intended.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
For image analytics, the subject device meets the predicates established acceptance criteria of 95% model conformance within 1.0mm distance to reference model and 2.0 degrees standard deviation for angular measurements. Surgery planning executes mathematical operations for estimated correction +/- 1 degree for angular measurements and +/- 1.0 mm for distance measurements.

Substantial Equivalence:
Bonelogic (K223757)
The Indications for Use of the subject device and the predicate device are similar. Both devices are intended to take medical imaging as an input and provide measurements from 3D structures to assist in surgical planning. The predicate device does this through the 3D model, and the subject device shows axes of patient anatomy in the context of a generic bone model through a series of images.
The subject and predicate devices have similar technological characteristics. The primary differences are the images needed as the input, the output of the software, the user interface and the items provided in the presurgical planning capabilities. In support of the claim of substantial equivalence the comparison between the subject and predicate systems, performance testing has been done to demonstrate that the differences do not introduce new questions of safety and effectiveness.

levels to determine substantial equivalence to the predicate device.
For image analytics, the subject device meets the predicates
established acceptance criteria of 95% model conformance within
1.0mm distance to reference model and 2.0 degrees standard
deviation for angular measurements. Surgery planning executes
mathematical operations for estimated correction $\pm$ 1 degree for
