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.
