The device description and performance studies focus on the material properties and mechanical performance of a ceramic femoral head, with no mention of AI or ML technology.
No This device is a component of a total hip arthroplasty, which is a surgical procedure to replace a damaged hip joint. While the overall procedure aims to alleviate pain and restore function, the device itself is a prosthetic implant, not a therapeutic device in the sense of delivering therapy.
No
Explanation: The device is a Zirconia Ceramic Femoral Head, an implantable component for total hip arthroplasty, which is a treatment for severe hip pain and disability. It is a prosthetic device, not a diagnostic one.
No
The device description clearly states it is a physical component (femoral head) made of ceramic material, intended for surgical implantation. It is a hardware device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
- Device Description: The Zirconia Ceramic Femoral Head is an implantable medical device designed to replace a part of the human hip joint. It is a physical component used in surgery.
- Intended Use: The intended use clearly states that it is designed to be "implanted into the human hip as a component in total hip arthroplasty." This is a surgical procedure, not an in vitro test.
The device is a surgical implant, not a diagnostic test performed on samples outside the body.
N/A
Intended Use / Indications for Use
The Zirconia Ceramic Femoral Head is designed to be implanted into the human hip as a component in total hip arthroplasty and is indicated for the following:
Patients suffering from severe hip pain and disability due to rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis, collagen disorders, avascular necrosis of the femoral head, and nonunion of previous fractures of the femur, patients with congenital hip dysplasia, protrusio acetabuli, or slipped capital femoral epiphysis; patients suffering from disability due to previous fusion; patients with previously failed endoprostheses and/or total hip components in the operative extremity; and patients with acute neck fractures.

Device Description
The Zirconia Ceramic Femoral Head (12/14 taper) is made from yttria stabilized zirconium oxide (ZrO2) ceramic and provides an alternative to cobalt-chrome alloy femoral heads. The Zirconia Ceramic Femoral Head is intended for mating with either a Tivanium® Ti-6Al-4V Alloy or Zimaloy® Cobalt-Chrome-Molybdenum Alloy modular femoral stem equipped with a tapered neck of identical dimensions. The Zirconia Ceramic Femoral Head is designed to articulate upon the UHMWPE-bearing surface of an acetabular component. The prosthesis is supplied in 26, 28, and 32 mm diameters and a variety of neck lengths.

§ 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.

Device Description: .
The Zirconia Ceramic Femoral Head (12/14 taper) is made from yttria stabilized zirconium oxide (ZrO2) ceramic and provides an alternative to cobalt-chrome alloy femoral heads. The Zirconia Ceramic Femoral Head is intended for mating with either a Tivanium® Ti-6Al-4V Alloy or Zimaloy® Cobalt-Chrome-Molybdenum Alloy modular femoral stem equipped with a tapered neck of identical dimensions. The Zirconia Ceramic Femoral Head is designed to articulate upon the UHMWPE-bearing surface of an acetabular component. The prosthesis is supplied in 26, 28, and 32 mm diameters and a variety of neck lengths.
Intended Use: .
The Zirconia Ceramic Femoral Head is designed to be implanted into the human hip as a component in total hip arthroplasty and is indicated for the following:
Patients suffering from severe hip pain and disability due to rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis, collagen disorders, avascular necrosis of the femoral head, and nonunion of previous fractures of the femur, patients with congenital hip dysplasia, protrusio acetabuli, or slipped capital femoral epiphysis; patients suffering from disability due to previous fusion; patients with previously failed endoprostheses and/or total hip components in the operative extremity; and patients with acute neck fractures.
Comparison to Predicate Devices: .
The Zirconia Ceramic Femoral Head (12/14 taper) is substantially equivalent to the femoral heads listed above as predicate devices. Each is designed to function as the modular femoral head component of a total hip prosthesis, is impacted onto the proximal taper of a femoral stem at the time of surgery, and articulates upon the UHMWPE-bearing surface of an acetabular component.
Both the Zirconia Ceramic Femoral Head (12/14 taper) and the Zimmer Zirconia Ceramic Femoral Head are made from zirconium oxide ceramic. The size range for the Zirconia Ceramic Femoral Head (12/14 taper) includes 26, 28, and 32 mm

diameters. The Zimmer Zirconia Ceramic Femoral Head is provided in 22, 26, and 28 mm diameters and supports a different taper for impaction upon the femoral stem component.
Clinical and Nonclinical Data .
Ceramic materials have been successfully used in orthopaedic applications for approximately 20 years. These materials exhibit excellent resistance to corrosion and wear and are highly biocompatible. The yttria stabilized zirconium oxide from which the Zirconia Ceramic Femoral Head is made has a limited clinical history. Although mechanical testing demonstrates that when used with polyethylene acetabular cups, the zirconia ceramic femoral head produces a relatively low amount of particulates, the total amount of particulate produced remains undetermined. Because of limited clinical and preclinical experience, the long-term biological effects of these particulates are unknown. Clinical investigation of the zirconium oxide ceramic prosthesis is ongoing.
