No
The description focuses solely on the mechanical design, materials, and physical characteristics of a revision femoral stem 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 cementless revision hip arthroplasty, which is a medical procedure to treat a condition (poor bone stock, deficiencies of the femoral head, neck or portions of the proximal femur) by replacing or restoring a body part.
No
Explanation: The device is a Revision Femoral Stem, an orthopedic implant used for hip arthroplasty, which is a treatment rather than a diagnostic procedure. Its intended use and description clearly indicate it is a prosthetic device for reconstruction.
No
The device description clearly details a physical implant made of Ti6Al4V and UHMWPE, intended for surgical implantation in the femur. It describes physical dimensions, materials, and mechanical testing, indicating it is a hardware device, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is a "Revision Femoral Stem" for "cementless revision hip arthroplasty." This is a surgical implant used in vivo (inside the body) to replace a portion of the femur.
- Device Description: The description details the materials and design of a physical implant (stem, neck, screw) intended for surgical implantation.
- IVD Definition: In Vitro Diagnostics (IVDs) are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This device does not perform such testing.
The information provided describes a surgical implant, not a diagnostic test performed on samples outside the body.
N/A
Intended Use / Indications for 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 24 mm, with increases of 2 mm, for a total of 6 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.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Mechanical testing had demonstrated the device's ability to perform substantially equivalent to the predicate devices in:

- -Fatigue testing (ISO 7206-6);
- Fretting evaluation:
- Analysis of disassembly torque of safety screw;
- Range of motion (ISO 21535). -
Clinical testing was not necessary to demonstrate substantial equivalence of Revision Femoral Stem to the predicate devices.

§ 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.
