The Modular PLUS Revision Stem is intended for cementless use in fractures of the femur where a long section of the bone is damaged and the stem must anchor into the distal half of the femur.
The Modular PLUS Revision Stem is a cementless two part modular stem that consists of distal anchorage module and proximal revision module, connected by a multi-stage tapered coupling, secured by a cylindrical screw. The proximal module has a standard 12/14 taper to accept modular heads. The Modular PLUS stem is manufactured from Ti-6Al-4V alloy that conforms to ASTM F136. The surface is grit blasted with corundum to produce a surface roughness of 4-6um. This submission adds three additional proximal modules, designated as size AX, BX and CX, have the same circumferential dimensions as the previously cleared AS/AL, BS/BL and CS/CL proximal modules. The differences lie in the overall length of the components. The AX module increases by 15.4mm, the BX module by 18.7mm and the CX module by 22.7mm.
This document is a 510(k) summary for the Modular PLUS Revision Stem, a medical device. It describes the device, its intended use, and claims substantial equivalence to a previously cleared device (K030971).
No acceptance criteria or study details proving a device meets acceptance criteria are provided in the given text.
The document discusses "Summary Nonclinical Tests" and states: "Engineering analysis shows that the bending stresses in the taper connection are less for the modified, longer modules." This is the only mention of any testing, but it does not specify acceptance criteria, test methodology, sample sizes, ground truth, or expert involvement, as this is a mechanical engineering analysis of a physical implant, not a study of an AI/ML device.
Therefore, I cannot provide the requested table or information regarding acceptance criteria and studies for an AI/ML device based on the provided text. The document is for a traditional medical device (hip stem) and does not involve AI/ML.

The differences lie in the overall length of the components. The AX module increases by 15.4mm, the BX module by 18.7mm and the CX module by 22.7mm.
Intended Use
The Modular PLUS Revision Stem is intended for cementless use in fractures of the femur where a long section of the bone is damaged and the stem must anchor into the distal half of the femur.
Summary of Technological Characteristics Compared to Predicate Device
The modifications to this device continue to be equivalent in design, fundamental scientific technology, indications and material to the Modular PLUS stem cleared on K030971.
Summary Nonclinical Tests
Engineering analysis shows that the bending stresses in the taper connection are less for the modified, longer modules.

Dear Mr. Webb:
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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (301) 594-4659. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address http://www.fda.gov/cdrh/dsma/dsmamain.html

§ 888.3360 Hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis.
(a)
Identification. A hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis is a device intended to be implanted to replace a portion of the hip joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum. This generic type of device includes designs which are intended to be fixed to the bone with bone cement (§ 888.3027) as well as designs which have large window-like holes in the stem of the device and which are intended for use without bone cement. However, in these latter designs, fixation of the device is not achieved by means of bone ingrowth.(b)
Classification. Class II.
