Intended Use
The Foundation® Press-Fit Hip Stem is intended for treatment of patients who are candidates for total hip arthroplasty because the natural femoral head and neck have been affected by osteoarthritis, inflammatory arthritis, traumatic arthritis, rheumatoid arthritis, avascular necrosis or femoral neck fracture, and revision arthroplasty where bone loss is minimal. It is intended to be used press-fit.
Device Description
The proximal body is trapezoidal in cross-sectional geometry. The distal stem portion is conical in shape and has flutes to provide rotational stability. A coronal slot in the larger stems decreases implant stiffness. The stem is available with and without a calcar collar and has a Morse type taper to receive modular heads. The neck/stem angle is 132°. The Foundation® Press-Fit Hip Stem is fabricated from wrought/forged Ti-6AI-4V. The proximal body of the stem has a plasma sprayed surface to enhance press-fit fixation.

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

Yes
The device is a hip stem intended for total hip arthroplasty to treat conditions like osteoarthritis and avascular necrosis, which directly addresses and treats a medical condition.

No
The device is a hip stem intended for surgical implantation in patients undergoing total hip arthroplasty, not for diagnosing medical conditions.

No

The device description clearly details a physical implant (hip stem) made of Ti-6AI-4V with specific geometric features and surface treatments, indicating it is a hardware medical device.

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

Here's why:

  • Intended Use: The intended use clearly states that the device is for the treatment of patients undergoing total hip arthroplasty due to various conditions affecting the femoral head and neck. This is a surgical implant used in vivo (within the body).
  • Device Description: The description details the physical characteristics and materials of a hip stem, which is a prosthetic implant.
  • Lack of IVD Characteristics: An IVD is a medical device used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not perform any such tests.

Therefore, based on the provided information, the Foundation® Press-Fit Hip Stem is a surgical implant, not an In Vitro Diagnostic device.

§ 888.3360 Hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis.

(a)
Identification. A hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis is a device intended to be implanted to replace a portion of the hip joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum. This generic type of device includes designs which are intended to be fixed to the bone with bone cement (§ 888.3027) as well as designs which have large window-like holes in the stem of the device and which are intended for use without bone cement. However, in these latter designs, fixation of the device is not achieved by means of bone ingrowth.(b)
Classification. Class II.

Trade Name: Foundation® Press-Fit Hip Stem

Common Name: Press-fit hip stem

Classification Name: Hip joint metal/polymer semi-constrained prosthesis

Description: The proximal body is trapezoidal in cross-sectional geometry. The distal stem portion is conical in shape and has flutes to provide rotational stability. A coronal slot in the larger stems decreases implant stiffness.

The stem is available with and without a calcar collar and has a Morse type taper to receive modular heads. The neck/stem angle is 132°.

The Foundation® Press-Fit Hip Stem is fabricated from wrought/forged Ti-6AI-4V. The proximal body of the stem has a plasma sprayed surface to enhance press-fit fixation.

Intended Use: The Foundation® Press-Fit Hip Stem is intended for treatment of patients who are candidates for total hip arthroplasty because the natural femoral head and neck have been affected by osteoarthritis, inflammatory arthritis, traumatic arthritis, rheumatoid arthritis, avascular necrosis or femoral neck fracture, and revision arthroplasty where bone loss is minimal. It is intended to be used press-fit.
