Korus System

The KORUS system was created with the aim to provide the surgeon with complete and reliable solutions for an increasingly personalized surgery.

The system includes: KORUS, two UNCEMENTED MODELS with CCD 135° and 125° angles, CEMENTED KORUS, also available with a DISTAL CENTRALIZER and MODULAR KORUS, provided with 14 interchangeable necks.- Available with or without distal centralizer.

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).

Materials 

High nitrogen content stainless steel (ISO 5832-9).

Finishing: mirror finishing.

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.
  • Step geometry converts torsional stresses into compressive loads.
  • Available in collared* or non-collared designs.

Materials

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

Modular Stem

  • 14 interchangeable necks to meet the patient’s real needs.
  • Two modular neck lengths available.
  • Standard version, 8° or 15° varus-valgus, 8° or 14° anteverted/retroverted, and four combined models.
  • Reduced neck geometry.

Materials 

Necks: cobalt chrome alloy (ISO 5832-12).

Stem: titanium alloy Ti 6Al 4V (ISO 5832-3).

Finishing: HA coating.

Collared Korus

  • Collar increases rotational stability.
  • Collar provides additional axial support and assist in achieving proximal loading.
  • The size of the collar increases with the size of the stem.

Materials 

Stem: titanium alloy Ti 6Al 4V (ISO 5832-3).

Finishing: HA coating.

Korus Titan 

Materials 

Proximal coating made of Titanium Y 367 APS (Air plasma Spray)

Distal section glass bead blasted
