SANTIM Anti-dislocation Dual Mobility Metal and PE Liners - China Suppliers and Factory Solutions
Special Description
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%)
Superior Range of Motion (ROM)
Flexion / Extension
Abduction / Adduction
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°.
Clinical Advantages
- 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, providing a maximum range of motion of more than 200 degrees.
- Guide Peg Design Better guidance for installation ensures the metal liner aligns with the acetabular cup axis, simplifying operation.
- Ultra Low Wear Rate Mirror polishing on the inside of metal liner forms a safe, low-friction interface with PE liners and ceramic heads.

Frequently Asked Questions
1. What are the primary indications for this hip implant?
Indications: Primary/Complex THA, Osteoarthritis, Hip Dysplasia (DDH), Avascular Necrosis, and patients at high risk of dislocation (e.g., dementia, Parkinson's). It is also ideal for high-activity patients (yoga, dance) and revision surgeries.
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. Always inform your radiologist before scanning.
3. Does this product support cemented or cementless fixation?
This system is designed exclusively for cementless fixation. It promotes excellent long-term bone growth for stable and durable fixation, eliminating the need for bone cement.
4. How does Dual Mobility reduce the risk of dislocation?
The dual-interface design increases the effective head-to-neck ratio. By using a large diameter liner, the jump distance required for the joint to dislocate is significantly increased, achieving a near "zero" dislocation rate.
5. What materials are used for the wear interfaces?
The system utilizes a mirror-polished metal liner combined with a high-grade polyethylene (PE) liner and can be paired with either a ceramic or metal femoral head to ensure an ultra-low wear rate.
6. Is this system suitable for patients with spinal disorders?
Yes, it is specifically indicated for patients with lumbar and spinal disorders involving the hip joint, such as ankylosing spondylitis or those who have undergone lumbar/spinal fusion surgery, where ROM is critical.
