Primary or Revision indications, Cemented or Cementless, Standard or Varus CCD

The design rationale of the HACTIV implant is based on the self-blocking concept. The cementless versions are made of titanium alloy and coated hydroxyapatite. The cemented versions are made of high nitrogen content stainless steel and are fully polished.

The cementless self-blocking concept has been validated by over 25 years of clinical use. The main characteristics are an immediate primary stability and a long term biological secondary fixation.

HACTIV is designed and manufactured in France, and includes the complete EVOLUTIS know-how in the industrial fileds of conception and manufacture of cementless femoral implants: more than 30.000 stems implanted since 2001 in France, Europe et in the world, with outstanding clinical results.
