The femoral head component, also known as the femoral ball head, is a critical part of a total hip prosthesis. It replaces the natural femoral head, which is the rounded end of femur that fits into the hip acetabulum. The femoral head component is designed to mimic the anatomy and function of the natural hip joint, allowing for smooth and stable movement.

Here is information of the femoral head component:

Material: Femoral head components are made from various materials, including metals, ceramics, and metal-ceramic composites. The most commonly used materials are:

Metal: Cobalt-Chromium-Molybdenum alloy (Cocrmo) and Titanium alloy. These metals provide excellent strength, durability, and biocompatibility.
Ceramic: Materials like zirconia-toughened alumina (ZTA) or ceramic composites offer superior wear resistance and low friction, reducing the risk of implant debris and long-term complications.

Design and Geometry: The femoral head component is typically spherical or ball-shaped, resembling the natural femoral head. It comes in various diameters to match the size of the patient's anatomy. The choice of head size is crucial as it affects the range of motion, stability, and wear characteristics of the artificial hip joint.

Head-Neck Ratio: The relationship between the diameter of the femoral head and the length of the femoral neck is essential for the stability and range of motion of the hip joint. Different head-neck ratios are available to accommodate varying patient anatomies and surgical approaches.

Bearing Surface Options: The femoral head component can be used in conjunction with different bearing surfaces in the acetabular cup. Common combinations include:

Metal-on-Polyethylene (MoP): The femoral head articulates against a polyethylene liner in the acetabular cup. This is one of the most widely used combinations.
Ceramic-on-Ceramic (CoC): Both the femoral head and the acetabular cup are made of ceramic materials, providing low friction and excellent wear characteristics.
Metal-on-Metal (MoM): Both the femoral head and the acetabular cup are made of metal, which may be used in select cases. However, MoM bearings have been associated with concerns about metal debris and are used less frequently nowadays.
Lubrication: The femoral head component articulates against the bearing surface in the acetabular cup, and the joint is lubricated by synovial fluid, reducing friction and wear. The design and materials of the femoral head aim to minimize wear debris and improve the longevity of the prosthesis.

Product features

• The CoCrMo forging alloy is very fine-grained and has a very high hardness. This makes this alloy ideally suited for both load-bearing and tribological components.
• excellent wear properties and high robustness
