Intended Use
The Trident® II Acetabular Shells described in this 510(k) submission are single-use sterile devices intended for cementless fixation within the prepared acetabulum. They are compatible with Trident® II X3® Polyethylene bearing inserts, which are also the subject of this submission. If additional fixation is desired, the dome screw holes, if present, have . been designed to accept Howmedica Osteonics 6.5mm or 5.5mm bone screws. The Trident® II Acetabular Shells described in this 510(k) submission are single-use sterile devices intended for cementless fixation with the mating Trident® II X36 Polyethylene Inserts. Indications for Use: - · Painful, disabling joint disease of the hip resulting from: degenerative arthritis, rheumatoid arthritis, post-traumatic arthritis or late stage avascular necrosis. - · Revision of previous unsuccessful femoral head replacement, cup arthroplasty or other procedure. - · Clinical management problems where arthrodesis or alternative reconstructive techniques are less likely to achieve satisfactory results. - Where bone stock is of poor quality or inadequate for other reconstructive techniques as indicated by deficiencies of the acetabulum.
Device Description
This Special 510(k) submission is intended to add the Trident® II Acetabular System. This system is a minor modification to the locking mechanism of the predicate Trident Acetabular System.

No
The 510(k) summary describes a mechanical implant (acetabular shells) and focuses on its intended use, indications, device description (a minor modification to a predicate device), and mechanical performance testing. There is no mention of AI, ML, image processing, or any software-driven analytical capabilities.

Yes.
Explanation: The device is an acetabular shell intended for hip arthroplasty, which is a therapeutic procedure to alleviate painful and disabling joint disease of the hip.

No

The device is an acetabular shell, which is an orthopedic implant for joint replacement, not a diagnostic tool. Its purpose is to fix joint disease, not to identify or monitor conditions.

No

The device description clearly states it is an acetabular shell system, which is a physical implant, not software.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states the device is for "cementless fixation within the prepared acetabulum" and for treating painful, disabling joint disease of the hip. This describes a surgical implant used in vivo (within the body), not a device used in vitro (outside the body) to examine specimens like blood or tissue.
  • Device Description: The description refers to an "Acetabular System," which is a component of a hip replacement.
  • Anatomical Site: The anatomical site is the "Hip," further confirming its use within the body.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples, detecting markers, or any other activities typically associated with IVD devices.

Therefore, this device is a surgical implant, not an IVD.

§ 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.

Dear Mr. Morcos:

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.
