The PLASTALLIUM™ system holds benefits for CEMENTED and CEMENTLESS fixation applications and is employed regularly in both approaches.

The surface topography of PLASTALLIUM™ 212 is ideal for mechanical interlocking of cement or bone. In the latter case, an additional coating layer of bio-conductive material (e.g. CAPTAL™ Hydroxyapatite) is employed to promote apposition of good quality bone to the implant.

Characteristics of Plastallium™

  • Static tensile strength 45-51 MPa
  • Static shear strength 40 MPa
  • Shear fatigue exceeding 130 MPa at 107 cycles
  • Cohesive strength greater than 45 MPa
  • Surface roughness (topography) Ra: 20-25 microns
  • High surface area
