Intended Use
Total hip components are indicated for Uncemented use in individuals undergoing primary and revision surgery where other treatments or devices have failed in rehabilitating hips damaged as a result of trauma, inflammatory joint disease such as rheumatoid arthritis, or noninflammatory degenerative joint disease (NIDJD) or any of its composite diagnoses such as osteoarthritis; avascular necrosis; traumatic arthritis; slipped capital epiphysis; fused hip; fracture of the pelvis; diastrophic variant; old, remote osteomyelitits with an extended drainage-free period; nonunion, femoral neck fracture and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques; femoral osteotomy; or Girdlestone resection; fracture dislocation of the hip; and correction of deformity. Smith & Nephew MIS Hip Stem components are intended for single use only and are to be implanted without bone cement.
Device Description
The Smith & Nephew MIS Stem is a straight, tapered, proximally loading stem designed to match the geometry of the femur. The stems are proportionally sized and shaped in sizes 1 through 9 and have modular neck options to address patient anatomy. The stems are manufactured from titanium alloy (Ti-6Al-4VI and the necks are manufactured from Cobalt Chrome. Each femoral stem is proximally coated with Smith & Nephew's Stiktite porous coating.

No
The document describes a mechanical implant and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.

Yes

The device is a total hip component, which is used in primary and revision surgery to rehabilitate damaged hips. This is a form of treatment, making it a therapeutic device.

No

The device description indicates it is a total hip component (an implant) used for surgical repair, not for diagnosing conditions.

No

The device description clearly describes a physical implantable device (femoral stem and neck components) made of titanium alloy and cobalt chrome, intended for surgical implantation. This is not a software-only device.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices intended to be used in vitro (outside the body) for the examination of specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes.
  • Device Description and Intended Use: The provided text describes a total hip component, which is an implantable medical device used in surgery to replace a damaged hip joint. It is used in vivo (inside the body) to restore function and alleviate pain.
  • Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing biological samples (blood, urine, tissue, etc.)
    • Using reagents or assays
    • Providing diagnostic information based on laboratory tests

This device is a surgical implant, not an IVD.

§ 888.3358 Hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis.

(a)
Identification. A hip joint metal/polymer/metal semi-constrained porous-coated uncemented 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 has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.(b)
Classification. Class II.

Dear Mr. Sinha:

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.
