Rectangular Femoral Stem - Ti6Al4V with Dual Coating by China Suppliers and Factory for Optimal Stability

Introducing our advanced implant solution crafted from Ti6Al4V material, featuring a dual coating of titanium and hydroxyapatite. Each side is coated with 225 micrometers of pure titanium and 70 micrometers of hydroxyapatite, promoting long-term bone ingrowth for enhanced integration. Designed by leading manufacturers in China, our implants exhibit a proximal rectangular cross-section that effectively resists both axial and rotational stress, ensuring maximum initial stability during the healing process. The unique lateral shoulder cutting design facilitates smoother implantation, minimizing surgical complications. Our proximal stepped design is engineered to optimize stress distribution, efficiently converting ring shear stress into axial compressive stress, which significantly improves axial stability. Additionally, the distal vertical and horizontal grooves enhance both rotational and axial stability, making our implants a reliable choice for medical professionals. As a trusted factory and supplier, we are committed to delivering high-quality products that meet the demands of modern orthopedic surgery, ensuring patient safety and satisfaction. Experience the innovation and reliability of our implants today.

    Frequently Asked Questions (FAQ)
    1. Which patients is this hip implant suitable for?

    It is suitable for Osteoarthritis, Femoral head necrosis, Femoral neck fracture, Rheumatoid arthritis, Ankylosing spondylitis, and Dorr types A, B, and C medullary canal morphology.

    It is also designed for standard primary hip replacement.

    2. Can patients undergo MRI scans after implantation?

    Yes, the implant is made from non-magnetic materials like titanium, titanium alloys, and cobalt-chromium-molybdenum alloys, ensuring MRI safety. JUST MEDICAL's products meet these standards, but always inform your radiologist before scanning.

    3. Does this product support cemented or cementless fixation?

    Designed exclusively for cementless fixation.

    Promotes excellent long-term bone growth for stable and durable fixation.

    Eliminates the need for bone cement.

    4. What are the key advantages of the Ti + HA double layered coating?

    The vacuum plasma sprayed Ti+HA double coating (225 µm Ti coating plus 70 µm HA coating) provides optimal surface roughness for mechanical interlocking and bioactivity, accelerating long-term biological fixation and osseointegration.

    5. How does the proximal stepped design prevent intra-operative fractures?

    The proximal steps convert hoop (circumferential) stresses into axial compressive loads, reducing peak hoop strain in the proximal femur, mitigating fracture risks and providing consistent seating height.

    6. What design features ensure rotational and axial stability?

    Initial stability is secured through the rectangular cross-section resisting torsional forces, complemented by the distal vertical and horizontal grooves that effectively anchor against axial and rotational migration.
