    Special Description

    SANTIM Anti-dislocation Dual Mobility

    Interface 1: Dual Mobility PE Liner-Femoral Head

    Normal range of motion (80%)

    Interface 2: Dual Mobility Metal Liner-Dual Mobility PE Liner

    Additional Range of Motion (20%)

    SANTIM Anti-dislocation Dual Mobility (6)

    Flexion / Extension

    SANTIM Anti-dislocation Dual Mobility (5)

    Abduction / Adduction

    SANTIM Anti-dislocation Dual Mobility (4)

    Internal / External

    ROM can be increased to over 200°, significantly surpassing industry standards.

    Compared to traditional prostheses, the dual mobility can increase flexion by 30°, adduction by 15°, and external rotation by 22°.

    SANTIM Anti-dislocation Dual Mobility (2)

    Excellent Compatibility

    The metal liner can match the conventional acetabular cup, realizing the flexible matching of multiple liners in one acetabular cup.

    Reduced Risk Of Dislocation

    Large diameter liner can effectively enhance the stability of joints and basically achieve "zero" dislocation rate.

    Guaranteed Initial Stability

    Screw fixation can be selected during the operation to avoid early loosening.

    Increased Range of Motion

    Dual Mobility structure design, which can provide a maximum range of motion of more than 200 degrees.

    Guide Peg Design

    Provide better guidance for the installation of the metal liner, ensure that the insertion direction of the metal liner is align with the axis of the acetabular cup, and is convenient for operation.

    Ultra Low Wear Rate

    Mirror polishing on the inside of metal liner can be compatible with movable polyethylene liner and ceramic head to form a safe and effective low friction interface.

    FAQ
    1. Indications and Contraindications
    A. Indications: Patients Suitable for This Hip Implant
    (1) Primary and Complex Primary Total Hip Arthroplasty (THA):
    • Primary or secondary osteoarthritis
    • Hip dysplasia (Developmental Dysplasia of the Hip, DDH)
    • Avascular necrosis of the femoral head
    • Displaced femoral neck fractures
    • Post-traumatic osteoarthritis
    (2) Patients at High Risk of Dislocation:
    • Cognitive impairment (e.g., dementia)
    • Insufficient lower limb muscle strength (e.g., cerebral palsy, Parkinson's disease)
    (3) Lumbar and Spinal Disorders Involving the Hip Joint:
    • Ankylosing spondylitis
    • Lumbar fusion surgery
    • Spinal fusion surgery
    (4) Special Activities (High Mobility):
    • Yoga, dance, and martial arts enthusiasts
    (5) Revision Patients:
    • Abductor muscle function impairment
    B. Contraindications: Patients Not Suitable for This Hip Implant
    (1) Active infections in the hip or other parts of the body
    (2) Significant organ diseases that are not effectively controlled
    (3) Severe vascular disease in the lower limbs
    (4) Frail individuals or those unable to tolerate surgery due to systemic diseases
    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 is the maximum Range of Motion (ROM) of the Dual Mobility system?

    The Dual Mobility structure design provides a maximum range of motion of more than 200 degrees, significantly surpassing industry standards. Compared to traditional prostheses, it increases flexion by 30°, adduction by 15°, and external rotation by 22°.

    5. How does the system reduce the risk of dislocation?

    It utilizes a large diameter liner that effectively enhances the stability of joints. This design fundamentally reduces stability risks and basically achieves a "zero" dislocation rate.

    6. What design features ensure the initial stability and low wear rate of the implant?

    Initial stability is guaranteed as screw fixation can be selected during the operation to avoid early loosening. For wear performance, mirror polishing on the inside of the metal liner matches the movable polyethylene liner and ceramic head to form a safe, effective, and ultra-low wear friction interface.
