Product Details
Rectangular Femoral Stem - Ti6Al4V Dual Coating for Bone Ingrowth | China Suppliers & Factory
Special Description
- The reduced lateral shoulder eases stem insertion.
- Rectangular cross section design resists axial/torsional stresses for initial stability.
- The proximal steps designed to convert hoop stresses to compression loads to avoid intra-operative fracture, and provide consistent implant seating height and initial stability.
- Distal vertical/horizontal grooves provide rotational and axial stability.
- Optimal offset aiming to restore hip biomechanics Ti6Al4V material and Ti+HA double layered coating (225 micron Ti coating plus 70 micron HA coating) ensure long-term bone ingrowth.
- Proximal stem stepped design Optimizes stress distribution by converting circumferential shear stress to axial compressive stress, enhancing axial stability.
- Distal stem vertical / horizontal groove design Provide rotational and axial stability.
- Side shoulder cutting design Easy implantation process.
- Base material: TC4, Ti + HA double coating
- Ti coating thickness: 225 µm HA coating thickness: 70 µm
- Excellent long-term bone ingrowth.

Frequently Asked Questions
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, eliminating the need for bone cement.
4. What is the composition and thickness of the coating? +
The implant features a Ti+HA double layered coating applied via vacuum plasma spraying. This includes a 225-micron Titanium (Ti) coating followed by a 70-micron Hydroxyapatite (HA) coating to optimize long-term bone ingrowth.
5. How does the proximal step design help prevent intra-operative fractures? +
The proximal steps are engineered to convert circumferential hoop stresses into axial compression loads. This biomechanical conversion reduces the risk of intra-operative fractures and ensures consistent seating height and initial stability.
6. What material is the DELTA™ Classic Stem made of? +
The base material of the DELTA™ Classic Stem is Ti6Al4V (TC4) titanium alloy, which offers excellent biocompatibility, high strength, and corrosion resistance for orthopedic applications.
