The document describes a hip implant component (femoral head and polyethylene insert) made of ceramic and UHMWPE. There is no mention of software, algorithms, or any computational processing that would suggest the use of AI or ML. The description focuses on material, design, and compatibility with existing components.
Yes
This device is a prosthetic implant (hip replacement components) used to treat painful, disabling joint diseases of the hip; therefore, it is a therapeutic device.
No
The device is described as an alumina ceramic femoral bearing used in hip arthroplasty, which is a reconstructive surgical procedure, not a diagnostic one.
No
The device description clearly indicates that the device is a physical component (alumina ceramic femoral bearings and polyethylene inserts) intended for surgical implantation, not a software application.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- Device Description: The provided text describes a hip implant (femoral heads and polyethylene inserts) used in surgical procedures to replace damaged hip joints. These are implanted directly into the body.
- Intended Use/Indications: The intended use and indications clearly describe the treatment of painful and disabling joint disease of the hip, revision of previous procedures, and addressing bone stock issues. These are all related to surgical intervention and not the analysis of in vitro specimens.
The device is a surgical implant, not a diagnostic tool used outside the body.

Intended Use / Indications for Use
The Osteonics® Alumina C-Taper Heads are single-use devices and may be used with all appropriately selected, legally marketed Osteonics Ti6A14V alloy femoral stems that incorporate a C-Taper trunnion. Additionally, the Osteonics® 36mm Alumina C-Taper Head is intended for use with any appropriately selected Osteonics® Trident™ Polyethylene Inserts and associated Trident™ Acetabular Shell.
Indications
- Painful, disabling joint disease of the hip resulting from: degenerative arthritis, rheumatoid arthritis, post-traumatic arthritis or late stage avascular necrosis.
- Revision of previous 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 is inadequate for other reconstructive techniques as indicated by deficiencies in the acetabulum.

Device Description
Osteonics® Alumina C-Taper Heads are alumina ceramic femoral bearings that have been designed for assembly, through a taper lock mechanism, to Ti6A14V alloy stems with the Osteonics® C-Taper trunnion design. This line extension to The Osteonics® Alumina C-Taper Heads adds the 36mm diameter size, with neck extensions of +0mm and +5mm. The subject heads are identical in material and design to the predicate heads.
Osteonics® Trident™ Polyethylene Inserts are manufactured from UHMWPE. They are compatible with Trident™ design Acetabular Shells. The subject inserts have an inner diameter of 36mm in order to mate with the subject 36mm alumina head.

§ 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.

Predicate Device Identification
The Osteonics® 36mm Alumina C-Taper Head and mating Osteonics® Trident™ Polyethylene Insert is substantially equivalent to the following Howmedica Osteonics devices, which have previously been determined substantially equivalent by FDA:
- Osteonics® Alumina C-Taper Heads ●

- Osteonics® Trident Polyethylene Inserts (Osteonics® Generation II Cup Inserts) ●
Device Description
Osteonics® Alumina C-Taper Heads are alumina ceramic femoral bearings that have been designed for assembly, through a taper lock mechanism, to Ti6A14V alloy stems with the Osteonics® C-Taper trunnion design. This line extension to The Osteonics® Alumina C-Taper Heads adds the 36mm diameter size, with neck extensions of +0mm and +5mm. The subject heads are identical in material and design to the predicate heads.
Osteonics® Trident™ Polyethylene Inserts are manufactured from UHMWPE. They are compatible with Trident™ design Acetabular Shells. The subject inserts have an inner diameter of 36mm in order to mate with the subject 36mm alumina head.
Intended Use:
The Osteonics® Alumina C-Taper Heads are single-use devices and may be used with all appropriately selected, legally marketed Osteonics Ti6A14V alloy femoral stems that incorporate a C-Taper trunnion. Additionally, the Osteonics® 36mm Alumina C-Taper Head is intended for use with any appropriately selected Osteonics® Trident™ Polyethylene Inserts and associated Trident™ Acetabular Shell.

- Clinical management problems where arthrodesis or alternative reconstructive techniques are less likely to achieve satisfactory results.
- Where bone stock is of poor quality or is inadequate for other reconstructive techniques as indicated by deficiencies in the acetabulum.
Statement of Technological Comparison:
The substantial equivalence of the line extension for Osteonics® Alumina C-Taper Heads and the Osteonics® Trident™ Polyethylene Inserts to the predicate devices identified above-is based on equivalence in intended use, materials, design, indications and contraindications to the Osteonics® Alumina C-Taper Heads (K971409) and the Osteonics® Trident™ Polyethylene Inserts (Osteonics® Generation II Cup Inserts; K983382, K983502).

Dear Ms. Staub:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note:
