(89 days)
The 3.5mm, 4.0mm and 4.5mm Bone Bolt System is indicated for fixation of fractures, fusions, osteotomies, non-unions, and malunions of small bone fragments, long bones, and long bone fragments of clavicle, scapula, olecranon, humerus, radius, ulna, pelvis, tibia, calcaneus, femur, and fibula, and the bones of the hand and in both children (2-12 years) and adolescents (12-21 years) in which growth plates have fused or in which growth plates will not be crossed by Bone Bolt fixation.
The 5.0mm, 6.0mm and 7.0mm Bone Bolt System is indicated for fixation of fractures, fusions, osteotomies, non-unions, and malunions of long bones and long bone fragments of humerus, radius, ulna, tibia, femur and fibula, pelvis, sacrum, and the bones of the foot in adults and in both children (2-12 years) and adolescents (12-21 years) in which growth plates have fused or in which growth plates will not be crossed by Bone Bolt fixation.
The Bone Bolt System consists of various sizes and lengths of bolts and nut-sleeves, which are implanted from opposing bone surfaces to provide stabilization of bones and bone fragments for the fixation of fractures, arthrodeses, and osteotomies. The bolts and nut-sleeves are cannulated for use with guidewires for precise placement in bone. The Bone Bolt System includes optional washers of various sizes.
The provided text describes the 510(k) premarket notification for the "Bone Bolt System." It outlines the device's indications for use, description, predicate devices, materials, and performance data. However, the document does not contain information about a study proving the device meets acceptance criteria related to an AI/machine learning model.
The performance data section explicitly states: "No clinical or animal testing was conducted." The performance characterization was based on in vitro mechanical testing (Torsional Strength Testing, Driving Torque Testing, Axial Pull-out Strength Testing, Static and Dynamic Bending Testing) according to ASTM standards.
Therefore, I cannot fulfill the request to provide the detailed information about an AI/ML study, including:
- A table of acceptance criteria and reported device performance (for an AI/ML model)
- Sample size used for the test set and data provenance
- Number of experts used to establish ground truth and qualifications
- Adjudication method for the test set
- Multi-Reader Multi-Case (MRMC) comparative effectiveness study details
- Standalone (algorithm-only) performance
- Type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- Sample size for the training set
- How ground truth for the training set was established
The document describes a traditional medical device (metallic bone fixation fastener) and its clearance based on substantial equivalence to predicate devices, supported by in vitro physical performance data. The questions posed are highly relevant to the evaluation of AI/ML-based medical devices, but this document does not pertain to such a device.

Dear Hollace Rhodes:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal
{1}------------------------------------------------
statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

Image /page/4/Picture/0 description: The image shows the logo for The University of Utah. On the left is a large red block U. To the right of the U is the text "THE UNIVERSITY OF UTAH" in a serif font.
Additional Predicate Synthes 3.5mm Cortex Screws (K043185)
Reference Device Acumed Frag-Loc® System (K130986)
Materials:
The Bone Bolt implants are made from Ti-6Al-4V per ASTM F136. The Bone Bolt accessories are made from stainless steel per ASTM F899, polypropylene and silicone.
Performance Data:
The Bone Bolt System performance was characterized through the following tests, in accordance with ASTM F543-17 and ASTM F1264-16 Annex A4:
- Torsional Strength Testing
- Driving Torque Testing
- Axial Pull-out Strength Testing
- Static and Dynamic Bending Testing
No clinical or animal testing was conducted.
Substantial Equivalence:
The Bone Bolt System has the same intended use and uses the same design, materials, principles of operations, and similar range of sizes as the predicate devices, the DePuy Synthes Cortex and Cannulated Screws (K1616), and Synthes 3.5mm Cortex Screws (K043185). Side-by-side performance testing demonstrates that the Bone Bolt System has equivalent or statistically significantly better performance than its predicates. The Bone Bolt System's similarities in technological characteristics to its predicates and the reference device, the Acumed Frag-Loc® System (K130986), further support its substantial equivalence. Thus, the Bone Bolt System is substantially equivalent to the DePuy Synthes Cortex and Cannulated Screws (K161616), Synthes 3.5mm Cortex Screws (K043185).
§ 888.3040 Smooth or threaded metallic bone fixation fastener.
(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
