Intended Use
Revision Femoral Stem is indicated for patients whose bone stock is of poor quality or inadequate for other reconstruction techniques as indicated by deficiencies of the femoral head, neck or portions of the proximal femur. It is intended for cementless revision hip arthroplasty on both uncemented and cemented femoral implants.
Device Description
The Revision Femoral Stem consists of a femoral stem and a modular neck, assembled together through a taper coupling stabilized by means of a safety screw. When used in total hip arthroplasty, the Revision Femoral Stem prosthesis is intended for use with modular femoral heads and compatible acetabular cups. When used in partial hip arthroplasty, the Revision Femoral Stem prosthesis is intended for use with a Lock Bipolar Head. The stem is made of Ti6Al4V (ASTM F1472 – ISO 5832-3). The stem is straight, with a tapered profile, round finned section and a rounded tip to facilitate insertion. The external surface of the stem features a macro-roughened finishing obtained by sandblasting. Diameters ranging from 14 to 26 mm, with increases of 1 mm, for a total of 13 diameters are available. Two lengths (140 or 200 mm) for each diameter of the stem are available. The neck is made of Ti6A14V (ASTM F1472 – ISO 5832-3). The same material is also used for the safety screw, which also has a small pin made of UHMWPE (ISO 5834-2, ASTM F648) to help prevent loosening of the safety screw. Two (2) versions of the neck are available , one with a CCD angle of 131° and another with a CCD angle of 135°. Both the neck versions are available in 7 different heights. Distally, the external surface of the neck component features a macro-roughened finishing obtained by sandblasting; proximally, the surface of the neck component is polished to reduce the chance of polyethylene wear particles if the neck accidentally rubs against the polyethylene of the acetabular component.

No
The description focuses on the mechanical design, materials, and physical characteristics of a femoral stem and modular neck for hip arthroplasty. There is no mention of any software, algorithms, or data processing that would indicate the use of AI or ML.

Yes
The device is a Revision Femoral Stem intended for hip arthroplasty, which is a medical procedure used to treat a condition and restore function, hence it is a therapeutic device.

No
The document describes a Revision Femoral Stem, which is a surgical implant used in hip replacement and revision procedures. It is not a diagnostic device.

No

The device description clearly details a physical implant (femoral stem and modular neck) made of materials like Ti6Al4V and UHMWPE, intended for surgical implantation. This is a hardware medical device, not software.

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.
  • Device Description: The provided text describes a Revision Femoral Stem, which is a surgical implant used in hip replacement surgery. It is a physical device inserted into the body to replace a damaged part of the femur.
  • Intended Use: The intended use clearly states it's for "cementless revision hip arthroplasty," which is a surgical procedure.
  • Lack of IVD Characteristics: The description does not mention any testing of biological samples, analysis of bodily fluids, or any diagnostic purpose.

Therefore, based on the provided information, the Revision Femoral Stem is a surgical implant, not an In Vitro Diagnostic device.

  • Fatigue testing (ISO 7206-6);
  • Fretting evaluation:
  • Analysis of disassembly torque of safety screw;
  • Range of motion (ISO 21535).
    LAL testing has been performed to establish that the subject device meet the specified 20EU/device limit.

Clinical Testing: Clinical testing was not necessary to demonstrate substantial equivalence of Revision Femoral Stem to the predicate device.

§ 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.
