ALLY™ Bone Screws are indicated for use in bone reconstruction, osteotomy, arthrodesis, joint fusion, fracture repair, and fracture fixation, appropriate for the size of the device.
The ALL Y™ Bone Screws are fully threaded cortical screws offered in various diameters and lengths. All screws are manufactured from titanium alloy. The implants are single use only.
The provided text describes the 510(k) submission for the ALLY™ Bone Screws, a Class II medical device. It focuses on demonstrating substantial equivalence to a predicate device rather than presenting a study of its performance in a clinical setting against specific acceptance criteria in the way an AI/ML device would.
Therefore, many of the requested categories are not applicable to this submission. This device is a bone screw, not an AI/ML algorithm or software device.
Here's a breakdown of the available information based on your request:
1. A table of acceptance criteria and the reported device performance
For a traditional medical device like a bone screw, acceptance criteria typically refer to engineering specifications and performance testing results against established industry standards.
| Acceptance Criteria (ASTM F543 Standard) | Reported Device Performance (ALLY™ Bone Screws) |
|---|---|
| Static Torsion | Evaluated and met standards (specific values not provided in this summary) |
| Static Pull-out | Evaluated and met standards (specific values not provided in this summary) |
| Driving Torque | Evaluated and met standards (specific values not provided in this summary) |
| Screw Bending Strength | Engineering analysis completed and met standards (specific values not provided in this summary) |
| Bacterial Endotoxin (LAL) | Completed and shown to meet device limits |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
This information is not provided in the document. For engineering tests of a medical device, the sample size would typically refer to the number of screws tested for each mechanical property. The data provenance would be that the tests were conducted in a lab setting, not from clinical data.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
Not applicable. For a bone screw, "ground truth" is established through standardized mechanical testing and engineering analysis rather than expert consensus on clinical data.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. Adjudication methods are relevant for studies involving human interpretation (e.g., image reading) to establish ground truth, not for mechanical testing of a device.
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 device is a bone screw, not an AI/ML diagnostic tool requiring MRMC studies.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This device is a bone screw, not an AI/ML algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" for this device's performance is established by objective mechanical testing against ASTM F543 standards and engineering analysis. It is not based on expert consensus, pathology, or outcomes data in the traditional sense.
8. The sample size for the training set
Not applicable. This device is a bone screw, not an AI/ML algorithm that requires a training set.
9. How the ground truth for the training set was established
Not applicable. This device is a bone screw, not an AI/ML algorithm.

Dear Mr. Liou:
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. 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 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

§ 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.
