Primary femoral head prosthesis BIOLOX Delta

<b>Overview</b><br>Available in three material options: 4th‑generation ceramic (BIOLOX Delta), zirconium‑niobium (Zr‑Nb) alloy and Co‑Cr‑Mo. 4th‑generation ceramic delivers outstanding wear resistance, improved fracture toughness and high biocompatibility; large‑diameter options increase range of motion (ROM) and reduce dislocation risk. Zr‑Nb alloy employs in‑situ ceramic oxidation to achieve high hardness, improved fatigue resistance and low MRI artifact; it is nickel‑free. High‑polished Co‑Cr‑Mo offers reliable wear performance with multiple offset options for both primary and revision hip arthroplasty.<br><br><b>Materials and key features</b><br><ul><li>BIOLOX Delta 4th‑generation ceramic: very high wear resistance and enhanced fracture toughness.</li><li>Zirconium‑niobium (Zr‑Nb) alloy: in‑situ ceramic oxidation, high hardness, improved fatigue resistance and reduced MRI artifacts; nickel‑free.</li><li>High‑polished Co‑Cr‑Mo: dependable wear performance and multiple offset options.</li><li>Large‑diameter ceramic‑on‑ceramic options (e.g., 40 mm): increased ROM and reduced dislocation risk.</li><li>Excellent biocompatibility: ceramics reduce osteolysis incidence and may improve implant survivorship.</li><li>Applicable to primary and revision hip arthroplasty procedures.</li></ul><br><b>Additional product highlights</b><br><ul><li>Extremely low linear wear rates reported for 4th‑gen ceramic (example: as low as 0.005 mm/year).</li><li>Wear resistance improvement vs. traditional materials (reported ranges: 50–200×).</li><li>Design and material choices balance wear performance, fracture toughness and imaging compatibility.</li></ul><br><b>Technical specifications</b><br><ul><li>Trade name: BIOLOX Delta (4th‑generation ceramic option available).</li><li>Material options: BIOLOX Delta ceramic; zirconium‑niobium (Zr‑Nb) alloy with in‑situ ceramic oxidation; cobalt‑chromium‑molybdenum (Co‑Cr‑Mo) high‑polish.</li><li>Reported linear wear rate (ceramic): ~0.005 mm/year (example figure provided on product page).</li><li>Relative wear resistance: reported 50–200× higher vs. traditional materials.</li><li>Large‑diameter option available (example: 40 mm) to enhance ROM and reduce dislocation risk.</li><li>Zr‑Nb alloy: low MRI artifact, nickel‑allergy free.</li><li>Indications: primary and revision hip arthroplasty; intended to reduce osteolysis and extend implant survivorship.</li></ul>
