Cemented Hip Joint Stem – type Poldi

Cemented Hip Joint Stem – type Poldi

Most frequently used type of endoprosthesis in the Czech Republic. The third most widely used cemented stem in Europe.


The former manufacturer, POLDI Kladno, launched this stem’s production  as far back as 1972.  Since then, the model has become the most frequently used hip joint endoprosthesis in the country’s orthopedic clinics – over 165,000 of them have been successfully implanted to date.


  • Material: nitrogen steel (ISO 5832-9) 
    In comparison with implants made of stainless steel, this material is more durable and has a 3 times greater slippage ratio.
  • Conical neck 12/14 (Euro cone) with embossed surface 
    Optional choice of ceramic head.
  • 5th generation – over 150,000 implantations
    Unambiguous declaration of the implant’s quality and reliability.
  • Relatively small stem 
    Suitable also for mini-invasive operations.
  • CD angle 140°
  • Innovated instruments – 8 rasps (for each size of stem) with quick-grip handle
  • For optimal results we recommend combining with cemented cups by BEZNOSKA
