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).
