Intended Use
Total hip arthroplasty is intended to provide increased patient mobility and reduce pain by replacing the damaged hip joint articulation in patients where is evidence of sufficient sound bone to seat and support the components. Total hip replacement is indicated in the following conditions: - A severely painful and/or disabled joint from osteoarthritis, traumatic arthritis, rheumatoid arthritis, or congenital hip dysplasia. - Avascular necrosis of the femoral head. - Acute traumatic fracture of the femoral head or neck. - Failed previous hip surgery including joint reconstruction, internal fixation, arthrodesis, hemiarthroplasty, surface replacement arthroplasty, or total hip replacement. - Certain cases of ankylosis. The DePuy® C-Stem AMT Hip Stem is indicated for cemented use only.
Device Description
The C-Stem AMT hip is a collarless, tapered, press-fit femoral stem. It is manufactured from wrought stainless steel (Ortron 90° conforming to ISO 5832-9) and is polished overall. The stem is offered in 7 sizes, with each body size having either a standard or high offset. It may be used with commercially available modular femoral heads, either metal or ceramic, to form the femoral component of a total hip prosthesis. Accessory items include previously cleared cement restrictors and centralizers.
More Information

No
The document describes a mechanical hip stem and does not mention any software, algorithms, or AI/ML capabilities.

Yes
The device is described as a "Total hip arthroplasty" system intended to replace a damaged hip joint, which is a therapeutic intervention aimed at treating a medical condition and improving patient mobility and reducing pain.

No

The device description indicates it is a "collarless, tapered, press-fit femoral stem" for total hip arthroplasty, and its intended use is to replace a damaged hip joint. This classifies it as a therapeutic or prosthetic device, not one used for diagnosis.

No

The device description clearly states it is a physical femoral stem made of wrought stainless steel, which is a hardware component.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside of the body.
  • Device Description and Intended Use: The provided information clearly describes a surgical implant (a hip stem) intended to be surgically placed inside the patient's body to replace a damaged hip joint. It is a physical component of a total hip prosthesis.
  • Lack of IVD Characteristics: There is no mention of testing samples, analyzing biological markers, or providing diagnostic information based on laboratory analysis.

This device falls under the category of a surgical implant or prosthetic device, not an In Vitro Diagnostic.

§ 888.3350 Hip joint metal/polymer semi-constrained cemented prosthesis.

(a)
Identification. A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.

SUBSTANTIAL EQUIVALENCE:

Neither the intended use nor the fundamental scientific technologies of the DePuy" C-Stem AMT have changed from the legally marketed predicate devices, the DePuy Titan Porocoat® Hip Prosthesis (K001991) and the DePuy C-Stem System (K982918). They have the same material, intended use, indication method, packaging and method of manufacture. The design, while not identical to the predicates, does not raise of safety or effectiveness. DePuy believes that the DePuy C-Stem AMT is substantially equivalent to these two previously cleared devices.

Dear Ms. Weissman:

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.
