Material Options

• Ti-6Al-4V / Ti-6Al-4V ELI
• Elastic modulus ~110 GPa, close to natural bone to reduce stress shielding. Ideal for cementless fixation in young, active patients.
• Co-Cr-Mo Alloy (ISO 5832-12)
  High strength and excellent wear resistance, suitable for cemented stems, revision surgeries and high-load cases.
• 316L Stainless Steel (ISO 5832-1)
  Cost-effective with stable biocompatibility for economical implant designs.

Size Specifications

• Length: Extra-short (<90mm), short (90–110mm), standard (110–150mm), long (150–200mm) and extra-long (>200mm) for primary and revision procedures.
• Diameter: 4–20mm with graded sizing to fit different femoral canals.
• Key Geometry: CCD angle 125–135°, offset 38–45mm, tapered/anatomical profiles, with collared or collarless designs for different surgical approaches.

Surface & Coating Technologies

• HA Coating: 50–200μm bioactive coating that accelerates bone cell adhesion and osseointegration.
• Porous Coating: 200–500μm for bone ingrowth and strong mechanical interlock.
• Plasma-Sprayed Titanium Coating: Improves surface roughness for stable bone-implant contact.
• Sandblasting: Ra 3–10μm surface finish for mechanical engagement without additional coating.

• Polished Surface: Ra <0.2μm to minimize cement abrasion.
• Micro-textured & Phosphatized Finishes: Enhance bonding strength between the stem and bone cement.

Product Classification

• By fixation: Cemented, cementless, and hybrid fixation stems.
• Special types: Revision stems, modular stems, and unicompartmental stems for complex clinical needs.
