AI/ML Overview

The provided text describes a medical device, the "Fixone Biocomposite Anchor," and its 510(k) premarket notification. This document focuses on demonstrating substantial equivalence to a predicate device through bench testing and biocompatibility assessments, rather than presenting a study of AI/algorithm performance. Therefore, many of the requested criteria related to AI studies (e.g., sample size for test/training sets, ground truth establishment, expert adjudication, MRMC studies) are not applicable to this document.

However, I can extract information related to the acceptance criteria and the studies performed for this medical device.

2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)

The document does not specify exact sample sizes for each particular bench test. It indicates that "Bench test were performed" and "The tests demonstrated that the device performs in a substantially equivalent manner to the predicate device." These tests are typically conducted in a laboratory setting.

  • Sample Size: Not explicitly stated as a number of individual anchors or sutures. Each test would have involved a specific number of samples as per the relevant ASTM or ISO standard.
  • Data Provenance: The document states "AJU Pharm Co.,Ltd. / Korea" as the manufacturer. The testing was likely conducted in a laboratory setting, presumably in Korea or by a certified testing facility contracted by the manufacturer. This is prospective data generation through controlled laboratory experiments.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. This is not an AI/algorithm study involving expert review of medical images or patient data. The "ground truth" for this device's performance is established by adhering to widely accepted engineering, biocompatibility, and material testing standards (ASTM, ISO, USP).

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

Not applicable. This is not an AI/algorithm study involving expert adjudication. The "adjudication" is inherent in the pass/fail criteria defined by the standardized testing methods.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This is a medical device for orthopedic fixation, not an AI diagnostic or assistance tool.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done

Not applicable. This is a medical device, not an AI algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The "ground truth" is defined by the technical specifications and performance requirements established by recognized standards organizations (ASTM, ISO, USP) for medical devices of this type. For example:

  • Bench Tests: Mechanical properties (e.g., insertion torque, pull-out strength, fatigue) are measured against predefined engineering limits or compared directly to a predicate device's performance.
  • Biocompatibility Tests: Biological response (e.g., cytotoxicity, systemic toxicity, irritation, implantation response) is assessed against criteria specified in ISO 10993 series for acceptable biological safety.
  • Shelf-life Tests: Stability over time is assessed against physical, chemical, and functional criteria at accelerated and real-time aging conditions according to AAMI TIR17 and ASTM F 1980-02.

8. The sample size for the training set

Not applicable. There is no training set as this is not an AI/machine learning device.

9. How the ground truth for the training set was established

Not applicable. There is no training set as this is not an AI/machine learning device.

§ 888.3030 Single/multiple component metallic bone fixation appliances and accessories.

(a)
Identification. Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
