China Suppliers DELTA CLASSIC Rectangular Femoral Stem - Advanced Titanium Design for Enhanced Stability from 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

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 is the coating composition and thickness of the DELTA® Classic Stem?

  The implant features a Ti+HA double-layered coating on a TC4 base. The titanium (Ti) coating thickness is 225 µm, and the hydroxyapatite (HA) coating thickness is 70 µm, which facilitates excellent long-term bone ingrowth.

• 5. How does the stem design enhance initial and rotational stability?

  The rectangular cross-section design resists axial and torsional stresses. Additionally, the distal vertical and horizontal grooves provide rotational and axial stability, while the proximal steps convert hoop stresses to compression loads.

• 6. What sizes and neck angles are available for the DELTA® Classic Stem?

  The stem is available in specifications from 6# to 16#, with stem lengths ranging from 115mm to 170mm, offsets from 36mm to 46mm, and a standard neck angle of 132°.
