Uncemented Korus 

The KORUS uncemented stem was created with the aim to provide the surgeon complete and reliable solution for an increasingly personalized surgery.

Two UNCEMENTED MODELS with CCD 135° and 125° angles

Straight Uncemented stem

  • 135° and 125° CCD angle neck, mirror polished finishing and tapered geometry for increased ROM and decreased risk of impingement.
  • Threaded extraction hole.
  • Low trochanteric invasivity, easier insertion and reduced incision, especially with an anterior approach.
  • Proximal trapezoid section resists axial torsional stresses and facilitates osseointegration.
  • Vertical and horizontal grooves to increase the contact surface area and provide axial and rotational stability.
  • Square section distal design provides rotational stability with no contact with the cortical.
  • Step geometry converts torsional stresses into compressive loads.
  • Available in collared* or non-collared designs.
  • The stem is in compliance with European standards, having 12/14 morse taper (5°42’30’’).

Materials

  • Titanium alloy Ti 6Al 4V (ISO 5832-3).
  • Finishing: HA coating.

Straight Cemented stem

  • Available with or without distal centralizer;
  • Same instrumentation as uncemented KORUS;
  • The stem is in compliance with European standards, having approved 12/14 morse taper (5°42’30’’);
  • Proximal trapezoid section resists axial torsional stresses and facilitates osseointegration;
  • Threaded extraction hole.
  • Low trochanteric invasivity, easier insertion and reduced incision, especially with an anterior approach;
  • Skinny neck:
    • Better joint flexibility.
    • Increased ROM.
    • Reduced neck length
    • Shorter taper (- 2 mm).
