Device Description

The Portland Portland Ceramic (Biolox-Forte) Femoral Head is provided as a single component. The device is manufactured from an Alumina Oxide (Biolox-Forte) and is available in various sizes. The internal bore of the femoral head is designed to taper look (12/14) with the external male taper on a femoral hip stem providing articulation with a suitable acetabular module.

AI/ML Overview

The provided document pertains to a 510(k) premarket notification for the Portland Ceramic (Biolox-Forte) Femoral Head, a ceramic femoral head prosthesis. It describes the device, its indications for use, and a summary of testing performed to demonstrate substantial equivalence to predicate devices.

However, the document does not contain information typically associated with acceptance criteria and studies for AI/ML-driven medical devices.
Instead, it details the regulatory submission for a physical medical implant. Therefore, the questions about AI/ML device performance, ground truth, expert adjudication, and training/test set sizes are not applicable to this document.

The "SUMMARY of TESTING" section states that "Portland Orthopaedics, Ltd. has provided analytical and mechanical testing to demonstrate the substantial equivalence of and compliance to standards for the Ceramic (Biolox-Forte) Femoral Head." This suggests that the acceptance criteria for this medical device relate to its material properties, mechanical performance, and compliance with established standards for ceramic femoral heads, rather than diagnostic accuracy or algorithmic performance.

Without further information on the specific analytical and mechanical testing conducted, it is not possible to provide a table of acceptance criteria and reported device performance in the format requested for AI/ML devices.

SUBSTANTIAL EQUIVALENCE INFORMATION

The Portland Portland Ceramic (Biolox-Forte) Femoral Head described in this submission is substantially equivalent to ceramic femoral heads manufactured by DePuy, Exactech and Plus, based on similarities of design, intended use, material and manufacturing methods. As demonstrated by the test results and material and the differences in the Portland Ceramic (Biolox-Forte) Femoral Head do not raise any new issues of safety and effectiveness.

SUMMARY of TESTING:

Portland Orthopaedics, Ltd. has provided analytical and mechanical testing to demonstrate the substantial equivalence of and compliance to standards for the Ceramic (Biolox-Forte) Femoral Head.

Dear Ms. Duncan:

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.

Regulation Number and Section

§ 888.3353 Hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis.

(a)
Identification. A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.(b)
Classification. Class II.
