Intended Use
The Reliance® PF stem is a femoral component of a Total Hip System. It is intended to be used for primary or secondary reconstruction of the proximal femur damaged as a result of inflammatory, non-inflammatory, or traumatic joint disease. The Reliance® PF stem is intended to be used in conjunction with Howmedica's V40 femoral heads, Acetabular components, and unipolar and bipolar components. The stem can be press-fit into the proximal femur for fixation by mechanical interlock, or affixed with bone cement.
Device Description
The Reliance® PF stem is a femoral component of a Total Hip System. It is manufactured from forged cobalt-chromium-molybdenum (Vitallium®) alloy.

No
The summary describes a mechanical implant (femoral stem) and its material properties and intended use, with no mention of software, algorithms, or AI/ML capabilities.

Yes
Explanation: The device is a component of a total hip system intended for the reconstruction of the proximal femur damaged by disease or trauma, which directly addresses a health condition.

No
The device is described as a femoral component of a Total Hip System, intended for reconstruction of the proximal femur. Its function is to replace or reconstruct a damaged anatomical part, not to diagnose a condition.

No

The device description clearly states it is a "femoral component of a Total Hip System" manufactured from "forged cobalt-chromium-molybdenum (Vitallium®) alloy," indicating it is a physical implant, not software.

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

Here's why:

  • Intended Use: The intended use clearly states that the Reliance® PF stem is a femoral component of a Total Hip System used for surgical reconstruction of the proximal femur. This is a device implanted in vivo (within the body) for structural support and joint function.
  • Device Description: The description confirms it's a physical implant made of metal alloy.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or treatment.

IVD devices are used in vitro (outside the body) to analyze biological samples. This device is a surgical implant used in vivo.

§ 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.

The Reliance® PF stem is a femoral component of a Total Hip System. It is intended to be used for primary or secondary reconstruction of the proximal femur damaged as a result of inflammatory, non-inflammatory, or traumatic joint disease. The Reliance® PF stem is intended to be used in conjunction with Howmedica's V40 femoral heads, Acetabular components, and unipolar and bipolar components. The stem can be press-fit into the proximal femur for fixation by mechanical interlock, or affixed with bone cement.

The Reliance® PF stem is manufactured from forged cobalt-chromium-molybdenum (Vitallium®) alloy.

The substantial equivalence of the Reliance® PF stem is based on an equivalence in intended use, materials, design, operational principles, and relative indications and contraindications to Howmedica's HNR Hip System (K903563), DRG Femoral component (K936126), Premium Femoral Component (K936127), and Dow Corning Wright's McCutchen Hip System.

Testing has demonstrated that the endurance load exceeds the Semlitsch minimum of 630 lbs.
