FAQ
1. Which patients is this hip implant suitable for? +
Osteoarthritis, Femoral head necrosis, Femoral neck fracture, Rheumatoid arthritis, Ankylosing spondylitis, 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 coating options are available for the DELTA™ Stem? +
The DELTA™ Stem provides three distinct coating choices to accommodate different surgical needs:
1. Ti (Air Plasma Sprayed)
2. Ti (Vacuum Plasma Sprayed)
3. Ti+HA (Vacuum Plasma Sprayed)
5. What are the thickness and porosity specifications of the coatings? +
The coatings are designed with a porosity of 70% to enhance integration. The Ti (Titanium) coating has a thickness of 325 µm, while the HA (Hydroxyapatite) coating layer has a thickness of 50 µm.
6. How does the stem design contribute to stability and bone conservation? +
The rectangular dimension of the stem is engineered to conserve bone mass while delivering exceptional torsional stability. Additionally, the distal flutes provide a dedicated channel for blood and debris during insertion, reducing pressure and promoting reliable stability.
